One of the most underused of the evergreen hollies is the truly aristocratic Nepal holly, Ilex integra. This pyramidal tree to 35' becomes somewhat rounded with age. The glossy, nearly black foliage provides the perfect backdrop for the large (to 0.5") round orange-red fruits borne in profusion on female plants. The leaves are entire with no spines or are shallowly toothed near the tip. It is found in Japan, Korea, and eastern China growing in woodlands on low mountains. Nepal holly makes an excellent specimen or hedge into Zone 6 gardens. There are some reports the English holly (Ilex aquifolium) may serve as a pollinator. I have seen several forms in the nursery trade and am not convinced that all are the true species. Several appear to have the influence of I. pernyi or I. aquifolium.
As good as the species is, some of the cultivated forms are high on my list of outstanding evergreens. A highlight of my recent trip to Japan was seeing both male and female forms of the gold leaf selection 'Ogon'. The foliage of this cultivar emerges electric yellow and retains good color for most of the summer, lightening to bright chartreuse. Interesting to me was the fact that all the female forms appear to be more upright growers than the rounded male selections of 'Ogon'. It seems that most of what is grown in the United States is the female form. Long hedges of this colorful shrub are so bright, you could line runways with them and land planes during blackouts. Another colorful cultivar is 'Green Shadow'. Our selection at the Arboretum was received in 2000 and has grown through the roof of the Lath House. This Japanese form was brought to the United States by Barry Yinger and given to the JCRA by Dan Hinkley, former owner of Heronswood Nursery. The two-tone green leaves are broadly edged in creamy white. It has proven to be a vigorous, upright grower and deserves a place in any garden. Other selections mentioned in the literature include 'Bancroft' a heavy fruiting form, 'Bisexual' a self fertile selection, and 'Xanthocarpa' with yellow fruits. – Mark Weathington, Assistant Director
The Arboretum has many activities in which volunteers can use their talents. Currently, we have the following openings which we would like to fill immediately:
Plant Labelers – Work on labels, maps, and checklists for plants in the various gardens.
Tour Guides – Give guided tours to scheduled groups or Sunday tours to the general public, usually in the spring and fall.
Visitor Center Staff – Provide general information to visitors; ensure the Visitor Center has needed brochures and supplies.
Fund Raising Support – Provide administrative assistance to the associate director of membership and fund-raising events for special events and other fund-raising activities.
If you would like to help, please contact Barbara Kennedy, at (919) 513-7004 or firstname.lastname@example.org. – Barbara Kennedy, Volunteer Coordinator
Friends of the Arboretum Lecture – November 1, 2007 (Thursday) – 7:30 PM – Free for members, $5.00 for nonmembers
"Rain Gardening" presented by Helen Kraus, Ph.D., Department of Horticultural Science, NC State University. Want to make the most of rainfall when it comes? Come and learn about the mechanics of how to design and build a rain garden. What is a rain garden? It is a garden designed to capture, use, and filter rain water runoff preventing it from entering the stormwater system. Rain that enters storm drains must be treated before it can be used again. Are rain gardens ugly? Nope! They are beautiful. In fact, you may have seen and admired one and not even known it.

"Growing Hardy Citrus in Zones 7b & 8" presented by Keith Endres, Ecologist, Landscape Characterization Branch, U.S. Environmental Protection Agency. With warmer winters the last decade, there has been a surge of interest in hardy citrus. By selecting fascinating new varieties and old cultivars developed by the USDA more than a hundred years ago, gardeners in much of the Southeast can experiment with their microclimates and grow some type of citrus. Not all varieties will produce commercial quality fruit, but many will be beautiful ornamental plants with culinary uses – not to mention a great conversation piece.
