Friends of the Arboretum Annual Plant Distribution
October 4, 2003 (Saturday) - 9:00 AM
Thousands of plants are being given away and they will disappear in a matter of minutes. Take a look at the list to see the plants we are giving away for yourself. Only the plants that are being given away in large numbers make this list. Many more do not make the list and will be a surprise on Saturday. The number before each plant represents the stake number that the plants will be behind. If you would like a copy of this list at this year's Annual Plant Distribution, please print the list now since we will only have a limited number of copies on Saturday morning. This list is accurate as of Saturday, October 2, 2004. This list will be modified several times prior to Saturday.

Abelia parvifolia - Schumann abelia Schumann abelia is a poorly known evergreen shrub, producing masses of pink flowers throughout much of the growing season. Known best as the abelia that was used in the hybridization of Abelia 'Edward Goucher', Abelia parvifolia (formerly known as A. schumannii) exhibits the upright growth habit common to 'Edward Goucher'. These plants are cutting grown from our plant growing in the Mixed Border. 20 Abelia parvifolia are available. |

Acer truncatum - Shantung maple Shantung maple is a small- to medium-sized deciduous tree, currently being hailed for its tolerance to a wide range of environmental stresses. Reputedly tolerant of climates across much of Texas, growing well both in Houston and El Paso. Our specimen has formed a nice, round-headed, small tree, about 15' tall, with superb, glossy, star-shaped leaves. Fall color ranges from yellow to vivid oranges and reds. This maple is also sometimes called purple-blow maple due to the vivid purple to copper-tinted new growth. 40 Acer truncatum are available. |

|
Aesculus parviflora - bottlebrush buckeye Bottlebrush buckeye is a deciduous shrub with a spreading growth habit and upright panicles of white flowers in summer. Although it is widely promoted, it is still not the most easily found shrub. For many years, our specimen has prospered in the Southall Garden under the shade of the old white oak. Specimens seen at other arboreta in the southeastern U.S. grow happily in full sun. Resistant to the leaf scorch that plagues most Aesculus, bottlebrush buckeye, since it does not lose its leaves to scorch, rewards you in the autumn with yellow fall color. 25 Aesculus parviflora are available. |

|
Agave celsii - agave Although not cold hardy in Raleigh, this is one of the most spectacular of the agaves. Agave celsii forms a large-sized plant (in areas where it is cold-hardy) with rich, bright green (not at all blue tinted) leaves and small, albeit sharp, teeth on the margins of the leaves. In some ways, this species more closely resembles the aloes than it does the agaves. Zone 8b and warmer. Protect in a cool greenhouse in colder climates, or else you'll be left with agave jello at the end of the winter. Our plants are seed grown from seed collected in Mexico. 110 Agave celsii are available. |

|
Agave gentryi × montana - hybrid hardy agave This naturally occurring hybrid agave was found growing in the mountains of northeastern Mexico. Both Agave montana and A. gentryi are fairly new species agaves that occur in pine forests in the Sierra Madre Orientale, where they form an understory layer along with other plants. Grow these in full sun to part sun conditions. Remember to protect the plants in the first year or 2 of establishment from cold winter temperatures, and also to prevent water from freezing inside the crown of the plant. In the southeastern U.S., agaves benefit from good drainage, so that in the autumn months plants shut down and harden off for the coming winter. 26 Agave gentryi × montana are available. |
| 6 |
|
Agave macroculmis - bigtooth agave This hardy, large-sized agave was grown by us from seed sent by Peckerwood Garden Foundation (Hempstead, Texas). Rarely seen offered in cultivation, bigtooth agave forms a striking specimen in any landscape. Observations here in Zone 7b have proven that this species is fully hardy here, provided that essential winter drainage concerns are met. Enjoy this fast-growing agave with bluish-green to gray-green foliage. 67 Agave macroculmis are available. |
| 7 |
|
Agave montana - mountain agave A newly described species of Agave collected from mountains in northeastern Mexico. Previously unknown to science. Since this plant occurs in montane environments (hence, "montana"), it should be quite cold hardy, likely through Zone 7b. Leaves are dark-green and smooth, growing to 3' by 5' in partial sun. Eventually, plants will produce flower spikes that rise to 15' or more. 60 Agave montana are available. |
| 8 |
|
Agave obscura - red-flowered hardy agave This hardy agave is about as obscure as its scientific name suggests. Agave obscura is a species native to mountains of northeastern and north-central Mexico. It is distinguished from other agaves by its dark red colored (instead of the normal bright yellow) flowers. Our plants also show the interesting orange-brown tinged leaf margins and marginal spines, contrasting with the rich green interiors of the foliage. As with other hardy agaves, sharp drainage is essential such that plants acclimate and do not keep growing in advance of the winter months. 27 Agave obscura are available. |
| 9 |
|
Agave striata var. falcata - sickle-leaf needle agave This agave looks like no other. The narrow, nearly tubular leaves (in cross-section) are curved on this naturally occurring variety of Agave striata, appearing sickle-shaped. The overall effect is that the rosette of highly prickly leaves looks curled, almost as if the plant has been given a coif before planted in the garden. Leaves are gray-green, sometimes tinged purplish. 23 Agave striata var. falcata are available. |
| 10 |
|
Agave striata var. striata - needle agave Needle agave is a unique among the agaves for its round, cylindrical leaves. Plants form dense rosettes crowded with these long, very sharply pointed leaves, the rosette reaching 24-36" across. A specimen growing in our Southwest Garden for over 10 years here at the JCRA readily offsets and has flowered several times. Flower spikes reach about 10' tall and are crowded with bright yellow, quasi-tubular flowers that attract insects and hummingbirds alike. Sharp drainage is essential for acclimation to cold winter conditions in all hardy agaves. 19 Agave striata var. striata are available. |
| 11 |
|
Arisaema heterophyllum - dancing crane cobra-lily This Asian species of Jack-in-the-pulpit has prospered for us here in our Lath House. Forming an erect plant, reaching up to 4' tall for us, Arisaema heterophyllum is not too dissimilar from our native green dragon -- Arisaema dracontium. Grow this plant for its unusual leaves, dissected and shaped roughly like deer antlers, and also for its lurid, green aroid flowers with a long drip-tip-like extended spathe. The fruits mature and turn bright orange-red in the autumn months. 50 Arisaema heterophyllum are available. |
| 12 |
|
Aucuba japonica 'Fructu Albo' - variegated dwarf Japanese aucuba Widely confused in the nursery trade with Aucuba japonica 'Variegata' is this plant. 'Fructu Albo' differs from other variegated Japanese aucubas by its dwarf stature and white fruits that are sometimes peach-pink in color as they mature. Plants we have grown here at the Arboretum mature at about 4' tall, while 'Variegata' can easily exceed 6' tall. A superb evergreen shrub for shaded sites. 25 Aucuba japonica 'Fructu Albo' are available. |
| 13 |
|
Berberis ×frikartii 'Telstar' - compact Frikart barberry This evergreen barberry is among one of several newly introduced taxa from Europe that we are trialing at the JCRA. Despite the abudance of species of Berberis, few to date have been grown in the southeastern U.S. Berberis ×frikartii represents hybrids between Berberis candidula (shimmering barberry) and Berberis verruculosa (warty barberry), both evergreen species with bright yellow flowers and dark, glossy green leaves, bright white-blue underneath. 'Telstar' forms a dense evergreen shrub to 4' tall, with dark evergreen, prickly leaves and pale yellow flowers. 20 Berberis ×frikartii 'Telstar' are available. |
| 14 |
|
Buxus sempervirens 'Pyramidalis' - upright common boxwood Boxwoods are commonly grown evergreen shrubs throughout much of the eastern U.S. In the Mid-Atlantic states, they are especially prominent. 'Pyramidalis' is an old cultivar, rarely seen or offered in U.S. commerce, that forms tight, narrow pyramidal specimens in time. Our 2 specimens growing where the old white oak (Quercus alba) once stood in the Southhall Garden show the beautiful upright form of this cultivar. Why this isn't more widely grown is beyond us! Native from southern Europe to the Black Sea and Caspian Sea regions, Buxus sempervirens is one of the toughest evergreens available to us as gardeners. Avoid poorly drained sites. 60 Buxus sempervirens 'Pyramidalis' are available. |
| 15 |
|
Buxus sempervirens 'Salicifolia Elata' - common boxwood Yet another superb cultivar of Buxus sempervirens that showcases an atypical growth habit. 'Salicifolia Elata' grows as a dense rounded evergreen shrub, but with side branches that gently cascade downward. Leaves are longer than most commonly seen Buxus sempervirens cultivars, too. These plants were propagated from the extensive Buxus collection house at the JCRA in the Southhall Garden. Native from southern Europe to the Black Sea and Caspian Sea regions, Buxus sempervirens is one of the toughest evergreens available to us as gardeners. Avoid poorly drained sites. 64 Buxus sempervirens 'Salicifolia Elata' are available. |
| 16 |
|
Callistemon 'Woodlander's Red' - hardy bottlebrush Introduced many years ago from the famous Woodlanders Nursery (Aiken, SC), 'Woodlanders Red' bottlebrush has continually impressed us with its cold hardiness and outstanding flowering display in the summer months. Whereas most bottlebrushes, including the most commonly seen one -- Callistemon citrinus -- are not cold hardy in Zone 7, 'Woodlanders Red' tolerates temperatures into the single digits, with only moderate burn of the foliage occurring below 5 degrees Fahrenheit. Plants are spreading in growth form (wider than tall) and produce red flowers clustered midway along the stems, in bottlebrush fashion (hence, the common name) in summer. Winter foliage color is usually red to purple. 49 Callistemon 'Woodlander's Red' are available. |
| 17 |
|
Camellia oleifera - tea-oil camellia This large shrub or small-sized evergreen tree is best known as the camellia used in hybridization programs in the U.S. to develop cold-hardy camellias for the Zone 6 climate. At the JCRA, we have long grown this species, with the excellent specimen at the entrance to the Klein-Pringle White Garden standing in testament to the species utility and beauty. Besides the excellent dark green foliage, the species also produces small (2" wide) white flowers in autumn (October to November). However, don't underestimate this plant for its beautiful, smooth bark -- golden-tan in color. In China, Camellia oleifera is valued for the oil obtained from its seeds. 29 Camellia oleifera are available. |
| 18 |
|
Camellia ×williamsii 'Mary Christian' - This camellia has been with us for many years at the JCRA, and it has consistently been a strong performer in the late winter months. 'Mary Christian' produces masses of dark pink flowers, semi-double, usually in February to March. Leaves are smaller than on the more familiar Japanese camellia cultivars. Camellia ×williamsii represents a group of man-made hybrids between the familiar Camellia japonica (Japanese camellia) and Camellia saluenensis (the Salween River camellia, native to western China). The name "williamsii" commemorates a great plant collector and patron of Victorian Era plant expeditions, J. C. Williams, in whose magnificent southwestern English garden (Caerhays Castle Gardens) the original cross first arose spontaneously between the two parental plants that had been planted adjacently. How fitting that a plant named for another "J. C." should grace the grounds of the JC Raulston Arboretum and your garden. 28 Camellia ×williamsii 'Mary Christian' are available. |
| 19 |
|
Canna - canna-lily Cannas are hugely popular herbaceous perennials, grown nowadays for their spectacular flowers -- yellow, orange, red, pink, and almost white -- and, in some cases, variegated foliage. Being a must-have plant of the 1970s and before, cannas subsided in popularity in the 1980s but re-emerged in the 1990s as garden plants par excellence. Cannas are perfectly cold-hardy in Zone 7, such that there is no need to undertake lifting the plants and storing them indoors over the winter months, as has to be done in colder climates. 6 Canna are available. |
| 20 |
|
Cephalotaxus fortunei - Chinese plum-yew Chinese plum-yew is a shade tolerant large evergreen shrub to small tree (ultimately reaching 15-20' in height). Our plants are derived from cuttings taken from the research plots at University of Georgia assembled by Dr. Donglin Zhang for his Ph.D. work while enrolled there. Chinese plum-yew differs strongly from the commonly grown Japanese plum-yew (Cephalotaxus harringtonia) by its much longer leaves, reaching up to 2 - 3.5 inches long. Leaves are soft to the touch. All Cephalotaxus are considered deer-resistant plants. 29 Cephalotaxus fortunei are available. |
| 21 |
|
Cephalotaxus harringtonia - Japanese plum-yew Now accordingly considered an evergreen shrub of the first rank, as it deserves, Japanese plum-yew is a fairly familiar plant of southern U.S. landscapes. Most plants seen are the shrubby forms or cultivars, including these plants which are derived from cuttings derived from the germplasm collection assembled by Drs. Michael Dirr and Donglin Zhang at the University of Georgia (Athens, GA). Cephalotaxus harringtonia is an excellent evergreen shrub, tolerating most environmental stresses, including heat, drought, shade, and sun. Deer will not bother these plants. Just make certain not to site plants on sites with exceptionally poor drainage. 36 Cephalotaxus harringtonia are available. |
| 22 |
|
Cephalotaxus harringtonia var. drupacea - shrubby Japanese plum-yew A superb needled evergreen shrub, Cephalotaxus harringtonia var. drupacea forms low, spreading plants tolerant of heavy shade to full sun conditions, as well as drought. The "drupacea" types are usually distinguished by their leaves that are arranged spirally around the stems -- versus in 2 planes along the stem as occurs in some cultivars of C. harringtonia. An excellent, bullet-proof shrub for a wide range of landscape situations. 30 Cephalotaxus harringtonia var. drupacea are available. |
| 23 |
|
Cercis canadensis subsp. mexicana - Mexican redbud Here, we offer hybrid-origin seedlings from our specimen of Mexican redbud growing at the east end of the Mixed Border. These plants are derived from open-pollinated seed collected off of our Mexican redbud specimen, thereby genetically representing 1/2 Cercis canadensis subsp. mexicana and 1/2 of unknown parentage. The only nearby other Cercis plants are 2 specimens of Cercis chuniana (Chun's redbud). As a result of this, expect a range of characteristics to occur among the plants offered. 60 Cercis canadensis subsp. mexicana are available. |
| 24 |
|
Cercis chinensis - Chinese redbud Small multi-trunked tree with densely crowded stems all arising from a basal crown. Bright pinkish-purple flowers open along stem in early spring before the heart-shaped leaves emerge. Unlike our native eastern redbud (Cercis canadensis), which is usually a single trunked tree, Chinese redbud bears flowers all along its many stems, creating wand-like columns of bloom. 10 Cercis chinensis are available. |
| 25 |
|
Chamaecyparis obtusa 'Ivan's Column' - upright Hinoki falsecypress This cultivar originated as a branch sport off of Chamaecyparis obtusa 'Blue Feather'. Like the plant from which is originated, 'Ivan's Column' has wonderful blue, soft foliage -- maintaining this trait even as a mature plant (unlike other falsecypresses). 'Ivan's Column' grows slowly, forming a narrow upright column with time. It is rarely offered by southeastern U.S. nurseries. Hardy to Zone 5. 53 Chamaecyparis obtusa 'Ivan's Column' are available. |
| 26 |
|
Chamaecyparis pisifera 'Gekko' - Sawara falsecypress 'Gekko', as an unfamiliar cultivar of Sawara falsecypress, grew for many years here at the JCRA, largely unnoticed as it prospered underneath several of the dwarf loblolly pines (Pinus taeda 'Nana'). Deciding that we needed to remove it to make way for other newer conifers, we propagated cuttings from our tree, prior to its removal, and offer it here for you. Similar in appearance to the familiar 'Boulevard' falsecypress for much of the growing season, 'Gekko' also boasts white-tipped (frosted) new growth in spring, showy from late winter through the spring and early summer months. Our plant, after about 15 years, measured 18' tall by 10' wide. Hardy to Zone 4. 32 Chamaecyparis pisifera 'Gekko' are available. |
| 27 |
|
Chamaecyparis pisifera 'Hakko' - Sawara falsecypress This obscure cultivar of Sawara falsecypress -- Chamaecyparis pisifera -- is not well known in the nursery trade. Our plant has grown since at least 1988 at the Arboretum, reaching from 6' tall then to nearly 15' tall now. We originally received this plant from Brookside Gardens (Wheaton, MD). 'Hakko' forms an upright, yet compact, tree, with feathery, juvenile foliage -- soft to the touch -- blue-green in color. Unlike 'Gekko', to which it is closely related, 'Hakko' does not produce white-tipped new growth in spring. Cutting grown from our plant in the Japanese Garden. 90 Chamaecyparis pisifera 'Hakko' are available. |
| 28 |
|
Chamaecyparis pisifera 'Lemon Thread' - gold-thread Sawara falsecypress The thread-leaf falsecypresses are well-known in southern gardens, mostly for their bright, yellow-leaf cultivars. 'Lemon Thread' originated as an adult-foliage sport off of 'Squarrosa Aurea', a juvenile-foliage cultivar. Our plant growing at the Arboretum was 3.5 feet tall in 1996, and had reached 8' by 2000. This cultivar is likely more slow-growing than the commonly seen 'Filifera Aurea', but is also larger growing than 'Mops' ('Filifera Aurea Nana'). We received our plant from the superb Buchholz and Buchholz Nursery (Gaston, OR). 30 Chamaecyparis pisifera 'Lemon Thread' are available. |
| 29 |
|
Chamaecyparis pisifera 'Plumosa Cristata' - plume Sawara falsecypress Nearly adjacent to our specimen of Chamaecyparis pisifera 'Gekko' stood an equally tall tree of 'Plumosa Cristata' in bed E46. Deciding that it, too, needed to be removed to make way for other conifers, we likewise propagated cuttings to make them available to you. 'Plumosa Cristata' Sawara falsecypress forms a tightly pyramidal, upright tree. Foliage is gray-blue-green and soft to the touch (as with all of the "Plumosa" group falsecypresses). At 15 years, our plant measured 20' tall by 8-10' wide. Hardy to Zone 4. 35 Chamaecyparis pisifera 'Plumosa Cristata' are available. |
| 30 |
|
Colocasia esculenta 'Black Magic' - purple elephant ear Reliably perennial in Z7 and warmer, this herbaceous plant has large, deep purple leaves attached to long petioles. Forms a dense clump and shows its colors best in full sun. Thrives in garden soils as well as in a container in a water garden. Deciduous. Striking. 51 Colocasia esculenta 'Black Magic' are available. |
| 31 |
|
Crinum bulbispermum 'Sacramento' - milk-and-wine lily This old cultivar of the familiar Crinum bulbispermum came to us from our friend Jenks Farmer (Columbia, SC). As Jenks is a Crinum grower and expert, we were happy to receive this unusual cultivar from him. Besides its blue-green, channeled, long leaves, plants of 'Sacramento' produce long fleshy scapes topped with several large, lily-like flowers, white with the centers colored a dark maroon-red. As for the species, this cultivar produces the curious, large, fleshy seeds -- which can litter the ground around the mature clumps. 'Sacramento' originated in South Africa and is regarded as one of the darker-colored cultivars of this fully, zone 7 hardy species. 97 Crinum bulbispermum 'Sacramento' are available. |
| 32 |
|
Cunninghamia unicanaliculata - China-fir China-fir (Cunninghamia lanceolata) has long been grown in the southern U.S. as an evergreen tree. In 1996, we were sent this new species by British plantsman Roy Lancaster. Although no longer recognized botanically, Cunninghamia unicanaliculata is distinct from other species mainly for its shrubby form and softer (to the touch) needles than other Cunninghamias. One of our older plants grew to 4' tall by 4' wide, and never appeared to be ready to assert a central leader. Try this unusual conifer out. At the least, enjoy it for its blue-tinged foliage, which blushes purple in the winter months. 14 Cunninghamia unicanaliculata are available. |
| 33 |
|
× Cuprocyparis notabilis - noble cypress Practically everyone is familiar with Leyland cypress (×Cuprocyparis leylandii), the ubiquitous columnar evergreen tree widely grown as a large-sized screening hedge in the southeastern U.S. Much less well known, however, is noble cypress (×Cuprocyparis notabilis), a hybrid between Arizona cypress (Cupressus arizonica) and Nootka falsecypress (Xanthocyparis nootkatensis). Plants grow rapidly, forming upright evergreen trees within a short period of time. Noble cypress is similar in many respects to Leyland cypress, but bears blue-green tinted foliage, instead of the dark sombre green of Leyland. 103 × Cuprocyparis notabilis are available. |
| 34 |
|
Dasylirion berlandieri - blue sotol As one of several cold-hardy sotols native to Mexico, Dasylirion berlandieri makes an architectural statement in the garden. It is valued chiefly for its twisted, steel-blue leaves, armed on their margins with sharp, spine-tipped teeth. As with the hardy agaves, the sotols should be sited in areas where they receive sharp drainage and lots of sunlight. Mature plants will reach 4' across or larger and will produce inflorescences measuring 15' tall or more. 43 Dasylirion berlandieri are available. |
| 35 |
|
Dryopteris filix-mas 'Cristata' - crested bear paw fern Grows up to 2' tall, highly fringed pale green fronds growing from short, thick, reddish rhizomes. Best in shade and moist soils. 14 Dryopteris filix-mas 'Cristata' are available. |
| 36 |
|
Erica ×darleyensis 'Mediterranean Pink' - Darley heath Although conventional widsom holds that heaths cannot be grown in the Southern states, Dirr describes the Erica ×darleyensis cultivars as a ìcredible starting point for finding heaths that are adapted to our climate. Among the literally hundreds of cultivars of heaths in existence, only a few can handle our heat and humidity. 'Mediterranean Pink' is a bright pink flowered winter-blooming heath, which for us flowers in profusion from March through early April. Plants are densely branched. Grows only 24" tall, forming a dense mound. Zone 6. Needs well drained soil. 12 Erica ×darleyensis 'Mediterranean Pink' are available. |
| 37 |
|
Euonymus alatus f. subtriflorus - wingless burning bush This botanical forma of Euonymus alatus has been growing at the Arboretum for 15 years, reaching only 4' tall by 6' wide. In many respects, it closely resembles burning bush (Euonymus alatus 'Compactus'), but does not bear the corky ridges or "wings" along the twigs. Leaves are small, dark green, turning fiery red to orange-red in autumn. 40 Euonymus alatus f. subtriflorus are available. |
| 38 |
|
Euonymus fortunei 'Wolong Ghost' - silvervein wintercreeper euonymus This great new groundcover, introduced by Hersonwood Nursery (Kingston, WA) has proven itself to be a winner for part-sun to part-shade garden spots. It is distinct among the wintercreeper euonymus in that its leaves display silver veins, while the rest of the leaf is a lustrous dark green color. Not as vigorous a grower as other euonymus, and will not take over your garden. Our plants have not shown any signs of euonymus scale at the JCRA. 18 Euonymus fortunei 'Wolong Ghost' are available. |
| 39 |
|
Fokienia hodginsii - Hodgins' cypress This eastern Chinese conifer, long overlooked in southern U.S. gardens, has attracted our attentions now for several years. A specimen growing in the Lath House bears attractive sea green leaves, broadly splashed with white marks underneath. Plants grown in full sun will remain dense, whereas those in shade tend to thin out, as has ours in the Lath House. Matures as a columnar evergreen, with a moderate to fast growth rate. These plants are seed-grown from our specimen. 12 Fokienia hodginsii are available. |
| 40 |
|
Gardenia augusta 'Daruma' - Cape jessamine One of several dwarf Cape jessamine cultivars introduced to us in recent years, Gardenia augusta 'Daruma' has been a standout in the Mixed Border at the JCRA. Reaching only 3' tall after 6 years in the ground, and producing single, white, exceedingly fragrant flowers, this is a gardenia that deserves wider recognition. Produces relatively few orange-red fruits. 20 Gardenia augusta 'Daruma' are available. |
| 41 |
|
Gomphrena 'Grapes' - gomphrena This herbaceous perennial produces tiny purple flowers on wiry, silvery stems. Gray-green foliage turns orange red in fall. Zone 8. 39 Gomphrena 'Grapes' are available. |
| 42 |
|
Habranthus robustus - rain-lily Bulbous herbaceous perennial grows to 9 in., linear, recurved spreading leaves appear after rose-red flowers, Argentina. 15 Habranthus robustus are available. |
| 43 |
|
Habranthus robustus 'Russell Manning' - rain-lily This outstanding cultivar of Habranthus robustus is one of the best performers of all the rain-lilies we grow here at the JCRA. With a rosette of flat, gray-green leaves serving as a contrasting base, groups of 7 or more, 3" large clear pink flowers (resembling amaryllis) rise up above the foliage on 12" scapes. Bulbs will produce flowers several times during the summer months, especially after dry periods that punctuate our Southern summers. 30 Habranthus robustus 'Russell Manning' are available. |
| 44 |
|
Hedera colchica (adult form) - Colchis ivy Colchis or Persian ivy (Hedera colchica) is a less commonly grown, but worthy, ivy in the eastern U.S. In its "juvenile" form, it grows as a vining evergreen groundcover, much like Hedera helix, except for its larger, darker-green leaves. At the entrance to our White Garden grew an adult ivy that was long labeled as Hedera helix (adult form). Thanks, however, to our friends at The Ivy Farm (Locustville, VA), we now know that this plant is correctly an adult (or shrubby) version of Colchis ivy. As one of the toughest plants around, adult ivies are perfectly suited as evergreen shrubs happy both in sunny and shady conditions. Our plant was readily propagated by semi-hardwood cuttings. Look for the interesting black fruits in autumn. Hardy to Zone 6. 93 Hedera colchica (adult form) are available. |
| 45 |
|
Helleborus ×hybridus - Lenten rose An outstanding group of evergreen herbaceous perennials, best known from the Lenten rose -- Helleborus ×hybridus. Most hellebores are valued for their pale green to white or pink flowers that are produced in the winter months. These seedlings are from our hybrids in the Winter Garden and so should produce some interesting colors. The female parent of these plants was the Ashwood Garden strain of Helleborus ×hybridus, which bears exceptionally strong-colored flowers. 40 Helleborus ×hybridus are available. |
| 46 |
|
Hemerocallis - daylily A well-known herbaceous perennial, valued chiefly for its outstanding display of large, lily-like flowers in summer. Flowers are typically colored golden-yellow, although shades of pink, purple, and lighter colors are now available. These plants are grown from seeds collected by former JCRA student worker, Jason Burris, from plants around the Arboretum. Due to the mixed parentage of these seedlings, flower color will be variable. 35 Hemerocallis are available. |
| 47 |
|
Hibiscus moscheutos - swamp rose-mallow Tall herbaceous perennial that can reach over 6'; large flowers in mid-summer in shades of red, pink and white; stiff stems may last through mild winters but the entire plant often dies back completely, emerging in warm spring weather. Full sun; moist soils best but adapts to garden soils; easily grown from collected seeds. 60 Hibiscus moscheutos are available. |
| 48 |
|
Hippeastrum - garden amaryllis An exceedingly popular genus of flowering bulbs, the amaryllis are commonly grown as forced bulbs in containers. However, we have known for many years here at the JCRA that practically all of the cultivars are perfectly hardy in Zone 7b -- thanks, in large part, to the work of NCSU Professor Emeritus, Dr. August DeHertogh. This assortment of amaryllis represents cultivars of which we've lost the identities on over the years. They are sure to please and reward you in your gardens for years to come. 60 Hippeastrum are available. |
| 49 |
|
Hydrangea lobbii - evergreen hydrangea This evergreen (yes, evergreen) hydrangea doesn't even look like a hydrangea with it's elongated fleshy leaves. It forms an upright shrub, our plant growing happily in the shade of our Lath House, and flowers in winter with lace-cap flowers bearing exceptionally large, white outer florets. Although it appears that this plant is not fully hardy in Zone 7b (our plant has burnt to the ground for the past 2 winters), this should be an exceptional plant in warmer zones. 29 Hydrangea lobbii are available. |
| 50 |
|
Hydrangea macrophylla 'Ayesha' - French hydrangea Hydrangea macrophylla, available now in multitudes of cultivars, remains an always popular deciduous flowering shrub. 'Ayesha' is a lesser known cultivar of Japanese origin, distinguished by its cupped and thickened sepals. (Yes, it's the sepals that give you the color you see in hydrangeas, not the petals!) The cupped sepals of 'Ayesha' (a mophead/hortensia cultivar) give the infloresence a slightly different look than "typical" cultivars with their flattened flowers. 'Ayesha' is most often seen in the pink, but will darken up in high pH soils. 20 Hydrangea macrophylla 'Ayesha' are available. |
| 51 |
|
Hypericum 'Brodie' - shrubby St. Johnswort This superb hypericum is listed either as a cultivar of Hypericum galioides or as a hybrid. Under either name, however, it is a superb landscape plant. The glossy, dark green, elongated leaves, mostly evergreen, combined with a spreading growth form, contributed to make this an excellent overall evergreen shrub. However, add to this mix stunning golden-yellow flowers with puffball-like stamens, and you have a real winner. In 6 years, our plant went from 6" tall to 3' tall with a 6' spread. 49 Hypericum 'Brodie' are available. |
| 52 |
|
Ilex ×attenuata 'Tinga' - Topal holly 'Tinga' is a superb, fast-growing evergreen holly, a female clone that sets abundant berry crops. Resembling the more familiar, and closely related 'Savannah' holly -- another Ilex ×attenuata cultivar, 'Tinga' bears darker green leaves that do not bleach out during the winter months. For a screening hedge, with the added bonus of large crops of bright red berries, this is a top-notch evergreen holly. 24 Ilex ×attenuata 'Tinga' are available. |

Ilex cornuta 'D'Or' - yellow-berry Chinese holly Although surprisingly poorly known, this cultivar arose as a sport of the indestructible Burford holly (Ilex cornuta 'Burfordii') with yellow berries instead of red. Our plant measured 12 feet tall in 1996, after which it was cut back to half its height, but now has already reached 15 feet in height. Grow it as a large evergreen shrub or a small-sized tree. Excellent for cut branches indoors in the winter for its large, showy yellow fruits. 42 Ilex cornuta 'D'Or' are available. |
| 54 |
|
Ilex crenata 'Golden Helleri' - golden Japanese holly This sport (originating at Centerton Nursery, NJ) of the commonly grown 'Helleri' holly has bright yellow foliage. Just as with 'Helleri', 'Golden Helleri' exists as a low spreading shrub, reaching 3' in height by 5' wide. Reports indicate that full sun and winter wind protection maintain the intensity of the foliage color. Our specimen prospered under part-sun/part-shade conditions, and at 14 years-old was only 5 feet tall, and slightly wider. We removed it to make way for other shrubs, and are offering you these newly propagated plants for your garden. 26 Ilex crenata 'Golden Helleri' are available. |
| 55 |
|
Ilex crenata 'Variegata' - Japanese holly This rarely seen variegted cultivar of the familiar Japanese holly will certainly not win any awards in the "best variegated plant of show" category, but it is an interesting plant. Ilex crenata 'Variegata' sports mostly green leaves, with an odd scattering of branches throughout the plant that bear gold-spotted or streaked leaves. This is one of those "where are you hiding the variegation" or "What you talking about, Willis?" variegated plants that is sure to fool and confound your neighbors. 21 Ilex crenata 'Variegata' are available. |
| 56 |
|
Ilex 'Patricia Varner' - Dodd hybrid evergreen holly This evergreen holly, virtually unknown in the nursery trade, has amazed us for several years now with its consistently heavy fruit set, outstanding foliage qualities, dense growth habit, and tight, conical form. 'Patricia Varner' holly was developed by famed Alabama plantsman and holly enthusiast Tom Dodd, Jr. (Semmes, AL). Parentage is uncertain, although Ilex pernyi (Perny holly) certainly must play some role in the hybridization of this plants. Hybrids with Perny holly usually have small leaves and large fruits, of which 'Patricia Varner' has both. Plants are grown from cuttings collected off of our tree growing behind the Finley-Nottingham Rose Garden. 37 Ilex 'Patricia Varner' are available. |
| 57 |
|
Ilex vomitoria 'Gray's Little Leaf' - littleleaf yaupon holly As one of several small-leaf cultivars of yaupon holly (Ilex vomitoria), 'Gray's Little Leaf' has grown for us for several years at the Arboretum, where it has formed a shrub reaching nearly 8' tall by 4' wide. Although this cultivar is a male, its outstanding foliar qualities (red-tinged new growth; dark green leaves through the growing season; and winter purplish color), combined with the overall dense form, make this an plant worthy of widespread use in gardens. 16 Ilex vomitoria 'Gray's Little Leaf' are available. |
| 58 |
|
Iris monnieri - iris of Rhodes This herbaceous perennial, beardless iris has long been grown and appreciated in the southern U.S. Scott Ogden regards this species as "among the most adaptable irises for all warm climates." Iris monnieri can reach up to 4' tall or smaller and bears bright pure yellow, fragrant flowers in May. A rhizomatous iris forming tight clumps, our plant has prospered in the Mixed Border to the point that we decided to divide it and offer some plants this year. 6 Iris monnieri are available. |
| 59 |
|
Iris prismatica - slender blue flag This eastern U.S. native iris is always a sight to see in spring, with its 2-toned lavender-purple and white flowers. Our specimen thrives in the shady conditions of our Lath House, such to the point that we decided to chop out half of the plant and make it available to you this year. Iris prismatica resembles Iris versicolor (northern blue flag), but can be told apart by its narrower leaves (usually less than 1/2 inch wide). Iris prismatica prefers moist soils and is native to eastern U.S. wetlands. Our form of this variable iris has blue to blue violet flowers with erect, linear leaves to 2 feet tall. Zone 5 or colder. 10 Iris prismatica are available. |
| 60 |
|
Iris sibirica (tall form) - Siberian iris Simply a taller version of the more familiar species; look for heights ranging over and above 4 feet; perfect for back border areas. Blue flowers; spring flowering. very hardy. 18 Iris sibirica (tall form) are available. |
| 61 |
|
Itea virginica 'Longspire' - Virginia sweetspire Not too often seen in cultivation is this cultivar of Virginia sweetspire, discovered and named by Woodlanders Nursery (Aiken, SC) owners Robert and Julia Mackintosh while canoeing the Augusta Canal near Augusta, GA. Of all the Itea virginica cultivars, 'Longspire' produces the, you guessed it, longest flowering racemes of all -- 8" long. A truly superb plant with year-round interest -- spring flowers, good summer foliage, excellent fall color, and winter twigs (reddish-purple), who can ask for more? 45 Itea virginica 'Longspire' are available. |
| 62 |
|
Jasminum floridum - showy jasmine This evergreen true jasmine bears trifoliate leaves with dark green, glossy leaflets. Forming a mounding shrub in time, due to its arching cane-like stems, older specimens are striking plants in the landscape. In mid- to late-spring, plants produce bright yellow flowers, never all at once, but certainly over a long period of time. These flowers do not bear the strong fragrance associated with the jessamines and other true jasmines. Cutting grown from our plants in the Mixed Border. Definitely hardy throughout Zone 7b, despite what the books say. 48 Jasminum floridum are available. |
| 63 |
|
Juniperus chinensis 'Blue Alps' - blue Chinese juniper This upright cultivar of Chinese juniper is valued chiefly for its brilliant silver blue foliage. Although the main branches are strongly ascending, the tips weeping ever so slightly, giving the plant interesting form. Specimens we have grown have prospered, reaching up to 9' tall in nearly 10 years. It's time for everyone to put aside the notion that Chinese juniper is only good for the Pfitzer and other related types. Cutting grown from our specimen in the Conifer Collection. 23 Juniperus chinensis 'Blue Alps' are available. |
| 64 |
|
Juniperus chinensis 'Variegated Kaizuka' - variegated Hollywood juniper This superb variegated juniper is a sport off of the popular Hollywood juniper (Juniperus chinensis 'Kaizuka', also known as 'Torulosa'). Although neither as fast-growing, nor as large-sized as 'Kaizuka', plants are very attractive for the interspersed patterns of variegated, green, and albino shoots throughout the plant canopy. Specimens of 'Variegated Kaizuka' do not display the degree of spiralling branches that 'Kaizuka' does, but still showcase this wonderful architectural feature. Cutting grown from our plant in the Conifer Collection. 25 Juniperus chinensis 'Variegated Kaizuka' are available. |
| 65 |
|
Juniperus rigida 'Hikari' - goldtip temple juniper This poorly known cultivar of temple juniper came to us from our friends at Yadkin Valley Nursery (Yadkinville, NC). It differs from typical Juniperus rigida in its new growth that emerges creamy-white to a pale gold color, contrasting nicely with the older dark green foliage from the previous growing season. Perhaps a bit slower in growth rate than the species. An upright juniper, likely to form a small tree to 20' tall in time. 22 Juniperus rigida 'Hikari' are available. |
| 66 |
|
Juniperus virginiana 'Silver Spreader' - eastern redcedar This odd variant of the ubiquitous eastern redcedar (Juniperus virginiana) differs from the norm of this species by its spreading growth habit and silver-tinged leaves. Originating from Monrovia Nursery (Azusa, CA) in the 1950s, plants have also been called 'Mona' and 'Dammii'). Our lone specimen, now growing on the back side of the Southwest Garden, was planted as a 1 gallon shrub in 1988, and has now reached 6' tall by at least 12' wide. 74 Juniperus virginiana 'Silver Spreader' are available. |
| 67 |
|
Ligustrum 'Carolina Gold' - gold-edge ligustrum This superb evergreen ligustrum seems to have no origin, except that a plant appeared here in 1996. Unfortunately, J. C. left us with no notes on where it came from. Growing in similar fashion to the golden Vicary privet (Ligustrum 'Vicaryi'), but with gold-margin variegation, instead of all-gold leaves, our specimen had grown to 12' tall in only 4 years. These rooted cuttings were generously supplied by the December 5, 2002 ice storm, which broke out several significant branches. Origin unknown for this one. Please contact us if you have any information you can contribute. 120 Ligustrum 'Carolina Gold' are available. |
| 68 |
|
Manfreda virginica - deciduous agave Possesses fleshy, dark green leaves up to 16" long and all originating from a basal rosette habit. Southeast North American native species, including North Carolina. Fragrant white flowers appear in June through August on tall spikes reaching up to 6 feet. 75 Manfreda virginica are available. |
| 69 |
|
Michelia figo 'Port Wine' - banana shrub The scent of the flowers from this evergreen shrub make it a must have for the garden. Although Michelia figo is somewhat common in Southern gardens as an evergreen, the cultivar 'Port Wine' is rarely seen or offered. Differing from the typical form by its much deeper purple-rimmed flowers (rich maroon-purple on the inside, too), 'Port Wine' is equally sweetly scented. Mature plants form shrubs (or small trees, if limbed up) 15 feet tall (or more) with a dense habit. Grows in partial shade to part sun. Zone 7b. 20 Michelia figo 'Port Wine' are available. |
| 70 |
|
Miscanthus sinensis 'Silberfeder' - silver feather grass One of the earliest of the miscanthus grasses to flower, often in early to mid-summer. Grows from 5' - 7' tall and flowers are silvery in color. Clump forming but will self sow. Full sun. 24 Miscanthus sinensis 'Silberfeder' are available. |
| 71 |
|
Myrcianthes fragrans - twinberry This evergreen shrub to small tree, native to north-central to central Florida, is completely new to us, having arrived via procurement from Woodlanders Nursery in South Carolina. Related to the "common myrtle" (Myrtus communis) of the Mediterranean region, "twinberry" displays numerous fragrant, white flowers (1" wide) with puffballs of stamens from April through June. The dark black-green, glossy foliage, emerging a coppery-orange color in spring, contrasts beautifully with the smooth, reddish-brown exfoliating bark. Now, some of you will balk at the notion of us growing (and recommending) plants native to central Florida in North Carolina, but the commonly grown evergreen shrub Illicium parviflorum ("yellow anise-shrub") is also native only to this region, and has proven hardy up to the mountains of NC. Present-day nativity isn't always a good predictor of cold hardiness. "Twinberry" can be, I feel confident, a phenomenal landscape plant for eastern NC. It might be one for an even larger region. Zone 7b, possibly colder. Sun. 68 Myrcianthes fragrans are available. |
| 72 |
|
Myrica heterophylla 'Robbie Green' - Southern bayberry This semi-evergreen relative of wax myrtle (Myrica cerifera) was received by us from Rushing Nursery (Semmes, AL) in 1999. 'Robbie Green' is a dwarf form of a poorly known native shrub called Southern bayberry. The leaves on this plant are larger and more olive green than other wax myrtles. Our plant, measuring 2 1/2 feet tall in 1999, is only about 3 1/2 feet now, a testament to the ability of 'Robbie Green' to stay dwarf. Myrica heterophylla is hardy to Zone 6, an entire zone more than the familiar wax myrtle. Grow it in full sun to partial shade. Myrica heterophylla grows wild on the Outer Banks of North Carolina and is very salt tolerant. 9 Myrica heterophylla 'Robbie Green' are available. |
| 73 |
|
Neillia uekii - Korean neillia Korean neillia is a poorly known species in a genus of suckering shrubs related to the more-familiar spireas. Acquired by us from Heronswood Nursery (Kingston, WA) in 1996, our plant now measures 5' tall by 7' wide. The arching stems bear attractive, lobed foliage, bright green, aging to a rich, dark green. In spring, clusters of small, white flowers adorn the branch tips, bedecking the entire plant in flowers. The neillias are a neglected group of cold-hardy, tough deciduous landscape shrubs suited to mass plantings due to their suckering growth habits. 30 Neillia uekii are available. |
| 74 |
|
Osmanthus fragrans f. aurantiacus 'Butter Yellow' - yellow sweet-olive Acquired by us from the famous Louisiana Nursery (Opelousas, LA) is this rarely grown cultivar of sweet-olive, Osmanthus fragrans. 'Butter Yellow' produces oodles of small, but highly sweetly scented, flowers that are -- you guessed it -- butter yellow in color. (Typical Osmanthus fragrans produces off-white colored flowers.) The many color-form cultivars of Osmanthus have unjustifiably remained obscure in commerce. Hopefully, we will soon see the start of wider cultivation and acceptance of this yellow-flowered cultivar among Southern nurseries and gardens. 11 Osmanthus fragrans f. aurantiacus 'Butter Yellow' are available. |
| 75 |
|
Pieris japonica 'Bisbee Dwarf' - dwarf Japanese andromeda This cultivar of Pieris japonica is valued chiefly for its small, twisted leaves -- these being only about 1/2 the size of typical leaves of P. japonica. During demolition of the old staff building near the Lath House, all of our Pieris collection was carefully assessed and cuttings rooted, so that we could preserve this important germplasm collection. Plants of 'Bisbee Dwarf' derive from these efforts. 24 Pieris japonica 'Bisbee Dwarf' are available. |
| 77 |
|
Pittosporum heterophyllum - Chinese pittosporum This fast-growing evergreen shrub ranks as a highly promising screening evergreen hedging plant for southeastern U.S. landscapes. Our lone specimen, growing at the northeast corner of the Lath House since 1988, was originally received by us from Brookside Gardens. It had reached 8' tall but was stubbed back in 1996, and now stands at 4-5' in height. A superb plant for its glossy green foliage and bright yellow, sweetly-scented flowers hidden amidst the foliage. Perfectly suited for shearing. 66 Pittosporum heterophyllum are available. |
| 78 |
|
Pittosporum tobira - Japanese pittosporum In the garden, Pittosporum tobira is valued as a durable evergreen shrub with pleasing foliage -- dark green older leaves that contrast with chartreuse newly emerging foliage. Flowers (only produced on older plants) are delightfully, sweetly scented, perfuming the air well away from the plant itself. Zone 7(a? or b?), possibly colder. Sun to part-shade. (Korean germplasm) - Despite the common name of this plant familiar to coastal North Carolina and Deep South gardens, plants distributed herein derive from germplasm collected in Korea in 1985. Although this germplasm has not seen much evaluative work done yet, we feel that it will prove to be more cold hardy than the Japanese germplasm that has been in cultivation for over 100 years. Join us in evaluating this new germplasm to see just how hardy and tough it really is. 65 Pittosporum tobira are available. |
| 79 |
|
Pittosporum tobira 'Turner's Dwarf Variegated' - dwarf variegated Japanese pittosporum This dwarf-sized Japanese pittosporum cultivar came originally to us before 1994 from sources unknown. Now listed from Monrovia Nursery (Azusa, CA), and likely other sources, this appears to be a cultivar that has been established in the nursery trade for some time, although it is not often seen in the southeastern U.S. 8+ year-old plants mature at about 2 to 2-1/2' tall by 3-1/2' wide, and bear medium-green leaves, edged with a prominent golden rim. Our original plant was lost, but we thank Juniper Level Botanical Gardens for restocking our collections with this wonderful dwarf pittosporum. 63 Pittosporum tobira 'Turner's Dwarf Variegated' are available. |
| 76 |
|
Pittosporum aff. truncatum - A number of hardy Pittosporum species have been introduced to our collections at the JCRA over the past 10+ years. Among the newer ones is this one that initially came in identified as Pittosporum truncatum -- an identity that we are treating as tentative. However, no matter the correct name, we have been impressed with the toughness and cold-hardiness of this species (as with other Pittosporum), surviving now for over 7 years in the ground. Expect a medium-sized mounding shrub, bearing glossy, somewhat thickened, evergreen leaves, and small, tubular, but sweetly scented pale yellow flowers in spring. 109 Pittosporum aff. truncatum are available. |
| 80 |
|
Platanus orientalis f. digitata - cutleaf Oriental planetree Unusual, cutleaf form of a large-sized, deciduous tree, reaching 100' in the wild (southeastern Europe to Transcaucasia). Our tree grew from 8 feet tall in 1988 to 39 feet in 2000, when it unfortunately had to be removed for the construction of the McSwain Center. Platanus orientalis f. digitata bears deeply lobed leaves, much more maple-like than any other planetree/sycamore, but still displays the typical white flaking bark, especially notable in winter. Zone 6. These plants are derived from rooted cuttings off of our original tree. 16 Platanus orientalis f. digitata are available. |
| 81 |
|
Podocarpus macrophyllus var. maki 'Edgefield' - Japanese yew-pine An old standby plant of the Coastal and Deep South, Podocarpus macrophyllus and its botanical variety maki have long graced Southern cities, homes, and campuses. 'Edgefield' is reputed to be more cold hardy, by at least 5 degrees Fahrenheit. We have not tested this yet, but are offering cutting-grown plants for your own gardens. 'Edgefield' derives from a plant growing in Edgefield County, SC. 8 Podocarpus macrophyllus var. maki 'Edgefield' are available. |
| 82 |
|
Prunus laurocerasus 'Forest Green' - common cherrylaurel This cultivar arose as a chance seedling at Bear Garden Nurseries (Silver Spring, MD). Touted as being more cold hardy than other cultivar of common cherrylaurel, 'Forest Green' is distinguished for its dark, glossy green leaves (appearing almost black-green) and strong growth. Our original specimen had reached 11' tall after 10 years in the ground. A functional landscape plant, useful for screening. Hardy throughout Zone 7. 12 Prunus laurocerasus 'Forest Green' are available. |
| 83 |
|
Prunus mume - Japanese flowering apricot 2003 saw some of the best fruiting we've ever seen on our Japanese flowering apricots -- Prunus mume -- in the Arboretum. Here, we offer you seeds collected off of our old specimen of Prunus mume 'Kobai' that once grew in the Winter Garden. Sadly, the mother plant was destroyed by the December 5, 2002 ice storm. Since these are open-pollinated seedlings, flower color will range from white to rose-pink to nearly red. 150 Prunus mume are available. |
| 84 |
|
Pseudocydonia sinensis - Chinese quince Occasionally grown for its fruits that can be used in jellies and preserves, we value Chinese quince (even our old leaning specimen in the Mixed Border) for its outstanding smooth, exfoliating bark. A small-sized flowering tree, Chinese quince produces medium-pink flowers in spring and then settles down as a small shade tree for the rest of the year. Old specimens have exquisite mottled bark, the flakes falling off in jigsaw-puzzle shapes -- orange-brown, tan, and gray. An incredible plant in winter. 12 Pseudocydonia sinensis are available. |
| 85 |
|
Quercus - Here's a little interesting fact. Mexico is the center of diversity for Quercus, the oaks. That means that there are more oaks native in Mexico than anywhere else in the world. The JCRA has had a long history of trialing Mexican plants for their adaptability to the climate of North Carolina, and largely, we have been continually surprised with the cold hardiness and adaptability of these plants to our climate. This oak (not identified to species) is a Mexican collection (acorns collected at 4600' elevation in the Mexican state of Tamaulipas) from a species growing in dry scrub vegetation. Plants should form small, multi-trunked specimens with narrow evergreen to semi-evergreen leaves. JCRA accession #011737. 17 Quercus are available. |
| 86 |
|
Quercus - These plants were grown from acorns collected from the old Mexican oaks growing in our field nursery. With at least 8 different species growing there, and knowing of the propensity of Quercus to hybridize, you're likely to get a Mexico oak medley out of this batch. Not that that's all bad, since so many of the Mexican species oaks have outstanding ornamental qualities, including glossy, semi-evergreen leaves, pink-tinged when flushing in spring. 13 Quercus are available. |
| 87 |
|
Quercus dentata - Japanese emperor oak This rarely grown oak hails from Japan, Korea and China, where it forms large trees reaching as high as 80 feet tall. We value this tree primarily for its spectacular stout shoots and huge broadly lobed leaves, covered in felted pubescence, especially on the new growth. It is a member of the white oak group, easily noted by the rounded (versus pointed) lobes on the margins of the leaves. Leaves can reach dinner plate proportions, up to 20" long by 12" wide. These seedlings are derived as second-generation plants from trees originally donated to us by Taylor's Nursery (Raleigh, NC). The plants donated by Taylor's Nursery were 5 inches tall in 1995, and grew to 15-20 feet tall by 2002, such that we were able to donated about 40 trees both to the City of Raleigh and the NCSU Campus. Zone 6. 58 Quercus dentata are available. |
| 88 |
|
Quercus macrocarpa f. olivaeformis - olive-acorn bur oak Bur oak is a common oak native throughout the east and central U.S. In the prairie states, it becomes a very common tree, where it often occurs in the woodland margin/transition into true prairie lands. Bur oak is valued for its unusually large acorns, reaching 4" long or more. This botanical forma, f. olivaeformis, bears more rounded acorns (not as elongated) than is typical. A tough, drought-tolerant, deciduous oak. 9 Quercus macrocarpa f. olivaeformis are available. |
| 89 |
|
Quercus nuttallii - Nuttall oak Grown in the nursery industry, although not always correctly identified, is this oak, Nuttall oak (Quercus nuttallii -- or Quercus texana, if you want to hear the most confusing taxonomic name change in decades). Nuttall oak, native to the lower Mississippi Delta and adjacent areas, forms large-sized trees, somewhat reminiscent of old pin oaks as can be seen on the NCSU Campus. Many plants exhibit attractive purple-colored new growth, this color sometimes persisting for up to 2 months. These plants are grown from wild-collected seed in southwestern Mississippi, assuring correct identification. In the nursery industry, Nuttall oak is widely confused with Shumard oak (Quercus shumardii). 24 Quercus nuttallii are available. |
| 90 |
|
Quercus polymorpha - Monterrey oak One of the Tex-Mex native oaks, Quercus polymorpha is widely grown in Texas, but remains unknown in more easterly parts of the southern U.S. It has been marketed as Monterrey oak, since it is common in forests around Monterrey, Mexico. Fully cold-hardy for us for over 10 years, we are impressed with the sage-green, thick, leathery leaves, which emerge bright shrimp-pink in spring. Depending on winter lows, plants will be either semi-evergreen or deciduous. Although we have noted no winter damage on our specimens, poor drainage must be avoided for these oaks to prosper. 6 Quercus polymorpha are available. |
| 91 |
|
Quercus shumardii var. schneckii - Schneck red oak Schneck red oak is a close cousin to Shumard oak (Quercus shumardii) which is native in bottomland woods in the NC Piedmont. Q. s. var. schneckii differs from regular Shumard oaks in only a few technical details, and is native in the lower plains states, but will grow fine here in NC, where it will form a large-sized shade tree. Plant this oak for Raleigh, the city of oaks! 6 Quercus shumardii var. schneckii are available. |
| 92 |
|
Quercus variabilis - Chinese cork oak Grow your own cork! (Sort of.) Chinese cork oak is a seldom-encountered species in the southeastern U.S. Our specimen, located near the current parking lot, has grown from 1' tall in 1988 to over 30' tall today. It now is showing the thickened, deeply furrowed, corky bark common to this species. Although the cork produced by this tree is inferior in quality to the cork of commerce (derived from Quercus suber), the cork of Q. variabilis is used in China. An interesting, fast-growing oak. 10 Quercus variabilis are available. |
| 93 |
|
Rhododendron mucronulatum var. maritimum - seaside Korean rhododendron Korean rhododendron is one of the first of the rhododendrons to flower for us, producing lavender-rose-pink flowers before the leaves in early spring. We are offering cutting grown plants of R. mucronulatum var. maritimum, of which the mother plant dates back to the 1985 Korean Expedition, where this beach ecotype was collected. We have not assessed salt tolerance of this plant, but based on knowledge of its nativity, you should expect it to perform much better than other rhododendrons under these conditions. 20 Rhododendron mucronulatum var. maritimum are available. |
| 94 |
|
Sabal etonia - scrub palmetto This trunkless palm is a native of the sandy scrublands of the central peninsula of Florida. Scrub palmetto, unlike Sabal minor, which it superficially resembles, is at home in high-and-dry settings. With large, palmate leaves that can reach up to 6' high by 3' across, this is an impressive palm, especially when massed. Our plants are grown from seeds collected from Juniper Level Botanical Garden (Raleigh, NC), where this species has been grown for many years with little to no cold injury in winter (despite the species being native in Zone 9). Grow this palm in full sun for the ""tropical"" effect in your garden. (Protect these small seedlings for the first 2-3 winters from bitter cold temperatures.) Hardy to Zone 7b. 61 Sabal etonia are available. |
| 95 |
|
Salvia microphylla 'Hot Lips' - cherry sage Shrubby salvia possessing flowers in shades of solid white, red and white bicolors, and solid red. Flower colors change with the spring and summer temperatures. Zone 7. 48 Salvia microphylla 'Hot Lips' are available. |
| 96 |
|
Sarcandra glabra - sarcandra An evergreen groundcover, creeping along via underground rhizomes. Leaves are glossy, usually medium-green in color, and strongly toothed on their margins. In summer to fall, bright orange-red berries are produced in terminal clusters. (Yellow-berried forms are also known, but we have none of these to offer.) We have grown this plant in our Lath House, since it benefits from protection from direct sunlight. However, it also will exhibit foliar burn during the winter months, such that winter protection is needed. Best in Zone 8 gardens. 17 Sarcandra glabra are available. |
| 97 |
|
Saxifraga stolonifera 'Maroon Beauty' - strawberry geranium Groundcover for the shade which spreads by thin runners. Silvery foliage with marroon veins and white flowers. 40 Saxifraga stolonifera 'Maroon Beauty' are available. |
| 98 |
|
Spiraea betulifolia 'Tor' - birchleaf spirea This deciduous spirea grows as a dense shrub 3-4 feet tall. It is a lovely shrub with red-brown shooots and broadly ovate leaves, iridescent blue-green above, gray-green beneath. Flowers are white and are produced in round-topped inflorescences (corymbs) in mid-spring. 'Tor' is a selection made in Scandinavia of Spiraea betulifolia var. aemiliana. This plant is receiving rave reviews as one of the best fall coloring shrubs, for its bright red fall color. Here in Raleigh, we have seen yellow to oranges thus far. Zone 5. 24 Spiraea betulifolia 'Tor' are available. |
| 99 |
|
Symphoricarpos ×doorenbosii 'Pink Magic' - Doorenbos coralberry We acquired this outstanding coralberry from our friends at Heronswood Nursery (Kingston, WA) several years back. 'Pink Magic' has delighted us with its cranberry-pink colored fruits that color richly in autumn and persist through early- to mid-winter, until the birds realize that they are edible and then haul them off in their bellies. As a low to medium-sized deciduous shrub, fully hardy throughout NC, this is an excellent choice for those of you interested in extending the season by using colorful fruit-bearing shrubs. 20 Symphoricarpos ×doorenbosii 'Pink Magic' are available. |
| 100 |
|
Taiwania cryptomerioides Flousiana Group - Chinese coffin cypress This rarely seen cousin of Cryptomeria japonica has prospered for us for many years here at the Arboretum. We have grown 2 types -- Taiwania cryptomerioides (Taiwan coffin cypress) and this one, which represents plants native to mainland China and not to Taiwan. Plants are Cryptomeria-like, but with a much looser habit of gracefully downsweeping branches. Our specimen had its top broken out by the December 5, 2002 ice storm, and because of that, we have these cutting-grown plants to offer you. Expect this to form a tall, pyramidal evergreen, up to 30-40' tall over 15 years. 15 Taiwania cryptomerioides Flousiana Group are available. |
| 101 |
|
Taxus cuspidata 'Aurescens' - gold-flush Japanese yew Most true yews (Taxus) simply do not grow for us here in the NC Piedmont, mostly due to our heavy, poorly-drained clayey soils. As such, we have tried out several yews in the Lath House, growing these plants in raised beds. Taxus cuspidata 'Aurescens' looks like any other Taxus through most of the year, but in spring, with the onset of new growth enlivens the Lath House. Picture bright sulfur-yellow new leaves emerging, all set against a backdrop of dark, black-green sombre foliage. The effect is stunning, lasting for several weeks in spring. Our plant has matured at about 3' tall by 6' wide. 44 Taxus cuspidata 'Aurescens' are available. |
| 102 |
|
Thuja occidentalis 'George Washington' - golden American arborvitae An evergreen, pyramidal, coniferous tree, valued primarily for its bright, gold-variegated foliage on new growth, fading to bright green in the heat of the southeastern U.S. Dating back to a 1948 introduction out of Sherwood Nursery (Gresham, OR), 'George Washington' is one of several gold-variegated selections of American arborvitae. In spring, as the new growth is emerging, the combination of gold new shoots, set against the dark green older shoots, offers a particularly stunning scene, when viewed up close on the plants. Grown from cuttings taken from a 12+ year-old tree that was 15' tall. Zone 3. 67 Thuja occidentalis 'George Washington' are available. |
| 103 |
|
Thuja occidentalis 'Sherwood Moss' - dwarf American arborvitae This dense, dwarf evergreen conifer, forms a low, cone-shaped tree/shrub eventually rising to 4-6' tall. It produces only the needle-like, yet soft, bright green juvenile foliage, which in winter turns bronze to purple. Juvenile foliage is maintained even in old age in this cultivar. 'Sherwood Moss' arose at Sherwood Nursery (Gresham, OR) in 1968. 6" tall plants in the JCRA in 1996 were only 3' tall by 2000. Zone 3. 46 Thuja occidentalis 'Sherwood Moss' are available. |

Thuja plicata 'Winter Pink' - western redcedar This cultivar was introduced by J. C. in 1995 from the U. K. Originating at Kenwith Castle Nursery (Bideford, Devon, England), Thuja plicata 'Winter Pink' was named by renowned conifer expert Gordon Haddow. For us, this plant has prospered, growing rapidly from a 12" liner in 1995 to a 8' tall by 4' wide tree in 2002. The summer foliage color is quite distinct, a combination of blue-green, suffused with yellow; while in the winter purplish-pink tones come in. Dirr's statement of this cultivar being a "compact-mounded form" does not agree with our observations. Zone 5. 55 Thuja plicata 'Winter Pink' are available. |

Trachelospermum jasminoides 'Mandianum' - yellow Confederate jessamine This twining evergreen vine for shade to part sun has been hardy here at the JCRA for years. Originally obtained from Woodlanders Nursery (Aiken, SC) as Trachelospermum mandianum (which was later corrupted to Trachelospermum maudianum), we are unable to locate any other information about this plant anywhere. Basically, the flowers on this cultivar start out a darker yellow color than on other clones of Confederate jessamine. As for the species, flowers are exceedingly fragrant, tubular, and quite showy. Zone 7b. 15 Trachelospermum jasminoides 'Mandianum' are available. |

Viburnum 'Conoy' - Egolf hybrid viburnum 'Conoy' representing perhaps the best of U.S. Nat’l Arboretum hybrid viburnums bred by the late Dr. Don Egolf, is always a favorite plant among the viburnums at the JCRA. With outstanding glossy, dark, black-green foliage, semi-evergreen, and a dwarf stature (3-5' tall), this is a great plant. In spring, it produces flat-topped inflorescences containing small white flowers and are dark pink-red in bud. The plant appears bejeweled with these dazzling white flowers set against the glossy foliage. A plant worthy of all the accolades it receives from numerous authors. 29 Viburnum 'Conoy' are available. |

Viburnum integrifolium - lusterleaf viburnum We are unsure as to the exact identity of this excellent evergreen viburnum, which has been labeled for years (and probably all of its life) as Viburnum integrifolium. The true plant of this name is a Taiwanese species that looks completely different than our plant. Our plant is reminiscent of Viburnum rhytidophyllum (leatherleaf viburnum), but has remained much smaller and denser, reaching only 5' tall after many years. Grow this evergreen shrub, with highly textured foliage and white flowers in spring, in full sun to part shade. Plants offered here are cutting grown from our plant growing in the Viburnum Collection. 21 Viburnum integrifolium are available. |

Viburnum suspensum - Sandankwa viburnum A mainstay of Zone 8 and 9 gardens, Sandankwa viburnum is a well-known evergreen species of Viburnum in the Deep South. Although reputedly not reliably cold-hardy in Zone 7, our plant at the Arboretum has grown here for many years (>10), and is now over 6' tall -- although it has occasionally frozen back in bitterly cold winters (minimum temperature below 0 degrees Fahrenheit). Perfectly adapted to shearing, Viburnum suspensum is chiefly grown for its thick, leathery, glossy, evergreen foliage. Some people find the odor of the bruised leaves offensive. Note the warty-stems and white flowers produced in late summer. 31 Viburnum suspensum are available. |

Weigela - weigela Thanks to Suzanne Edney, we offer you this as yet unidentified weigela of Korean original. Brought to us by Suzzanne, many more plants rooted than we needed to plant out here at the Arboretum, so we are sharing these with you. This weigela is distinguished most strongly by its large, dark green leaves, tinged an iridescent blue when young. Flower color is unknown, but will be helpful in identifying this plant in the future. 27 Weigela are available. |

Weigela 'Red Prince' - common weigela This old cultivar of the common weigela has been a standout in recent years among other weigelas growing in the East Arboretum on the northern side (adjacent to Beryl Road). 'Red Prince', just as the name suggests, produces a great abundance of crimson red, tubular flowers with bright white stamens. This shrub is just one flowering machine. Although many new weigelas have been introduced in recent years, not all of these can compete in terms of their floral performance with this cultivar. Has done extremely well, even with our summer heat and recent droughts. 24 Weigela 'Red Prince' are available. |

Wisteria frutescens 'Amethyst Falls' - American wisteria The Asian wisterias, with their excessive vigor have given all wisterias a bad name. Our American native species also offers gardenworthy performance, albeit different than that of the Asian plants. 'Amethyst Falls' is greatly restrained in its growth rate, blooms later so that the flowers are rarely lost to frost, and also produces sporadic blooms during the summer months. What's there to lose? Well, fragrance for one thing, as the flowers are not fragrant. An excellent garden plant first introduced by our friends at Head-Lee Nursery (Seneca, SC). 20 Wisteria frutescens 'Amethyst Falls' are available. |

Wisteria frutescens 'Longwood Purple' - American wisteria A new selection of one of our native wisterias, 'Longwood Purple' offers the deepest purple coloration available for this species. As interest in the two species of U.S. native wisterias grows, we are currently working hard to assemble all of the new and old cultivars, in order to see which ones turn out to be truly distinct from the typical form, and to see which plants prove to be the more garden-worthy cultivars. "American wisteria" produces flowers in smaller racemes (= "chains") than the Asian wisteria's, and the flowers emerge after the foliage but are still very showy. Join us in trying out this exciting new plant, which we originally acquired from our friend Ted Stephens at Nurseries Caroliniana in North Augusta, SC. Zone 5. 25 Wisteria frutescens 'Longwood Purple' are available. |

Zenobia pulverulenta f. nitida - honey-cups An outstanding semi-evergreen to deciduous shrub native to boggy sites from North Carolina south to Florida. Glossy green leaves are borne throughout the year, giving way very late in the season (late November to late December) to rich red and orange tints. Spring brings on clusters of large (1/2" wide) blueberry-like, urn-shaped flowers that hang from the branches and are strongly, sweetly scented. Sun to part shade. In cultivation, two distinct forms are grown: a powdery-blue-leaved form; and, less commonly, the green-leaf form. Here, we offer the green-leaf form, simply because it is not easily procured. Both forms are highly garden-worthy. Our plant, over many years has never exceeded 3-4' tall. Zone 5. 18 Zenobia pulverulenta f. nitida are available. |
