Plant of the Month

Cleyera japonica 'Tokyo Sunrise' – Japanese cleyera

Cleyera japonica 'Tokyo Sunrise'

by Mark Weathington, Assistant Director and Curator of Collections

Evergreen shrubs are the backbone of the southern garden from hollies to camellias and tea-olives to fatsia. Among the top tier of garden-worthy evergreens is Cleyera japonica (Japanese cleyera). Cleyeras have been somewhat confused in the nursery industry with the somewhat similar Ternstroemia gymnanthera masquerading as Japanese cleyera for many years until it was sorted out by NC State's Paul Fantz, Ph.D.

The JC Raulston Arboretum has been growing cleyera for many years and we have always appreciated this plant's subtle beauty and workhorse adaptability. We recently received the cultivar 'Tokyo Sunrise' and have quickly fallen for this outstanding variegated Japanese cleyera. This new selection of Japanese cleyera has a bold white edge to each leaf. New growth is flushed with orangish-red coloration precisely the color of sunrise off the east coast of Japan, the Land of the Rising Sun. This form appreciates some protection from afternoon sun but otherwise appears as tough as the species and should tolerate temperatures down to the single digits. Look for the JCRA's specimen in the Asian Valley near the entrance to the Japanese Garden.

JCRA members interested in procuring this plant for their own gardens are in luck. This outstanding garden plant will be available through our very first member's only Preorder Plant Sale along with about 40 other very special plants. Members should keep an eye out for the entire list of plants to come out very shortly. Nonmembers are always welcome to join the JCRA to take advantage of the benefits and privileges available to our supporters.

35th Anniversary Symposium

"Horticultural Madness"

September 23 and 24, 2011 (Friday and Saturday)

by Bobby Ward, Symposium Committee Member and Chris Glenn, Programs and Education Coordinator

From the founding of the JC Raulston Arboretum as the NCSU Arboretum in 1976, lectures by renowned speakers have been a major part of the Arboretum's focus. And symposia, sponsored from time to time, have been an additional opportunity for in depth study. "Horticultural Madness" brings to life the amazing and bizarre world of horticulture. In this two-day symposium, prominent speakers from the United States and Wales will enlighten us with lectures on an amazing year of living botanically; eccentric to insanely driven people and their plants; bizarre botanicals; attention grabbing plants and innovative combinations; favorites from an obsessive plant collector; extreme gardening experiences and plants; and a story by a traveller to the botanically rich area of northern Vietnam.

This is a unique opportunity to further the Arboretum's mission and your own personal horticultural obsessions. Register today by calling (919) 513-7005. A printable registration form is also available. Early registration ends August 31, 2011.

Open Days Garden Selection

Barbara and Loren Kennedy's garden

by Jayme Bednarczyk JCRA Member and Volunteer and Garden Conservancy Regional Representative

Many have wondered how Open Days gardens are selected. Since this year's Raleigh Open Days are next month, we thought we'd share how they're selected. Gardens must be at least two years old, exhibit a reasonable standard of maintenance, and possess one or more of the following characteristics:

  • Unity and harmony in the design
  • Strong and distinctive elements within the design
  • Appropriateness of the design in relation to the setting and surrounding landscape
  • Particularly effective or innovative use of the site or plantings
  • Interesting and/or unusual collection of plants
  • Aesthetic groupings of plants
  • Unique intermingling of plants and /or colors, textures, etc.
  • Aspects that educate, enlighten, and inspire the visitor
  • Ecologically sound design and maintenance techniques

In order to continue the program we need your to help us. If you know of a private garden you'd like to be recognized in the future as a Garden Conservancy Open Days garden, please contact Anne Porter at anne_porter@ncsu.edu or (919) 513-3826. For more information regarding the program and to see a complete schedule of the 2011 Open Days gardens throughout the country, please visit the Garden Conservancy's Web site.

Browse and Buy

Browse and Buy

by Barbara Kennedy, Volunteer Coordinator

Our Browse and Buy Program, selling garden related books for $5.00 to the public in the Bobby G. Wilder Visitor Center, has been quite successful. We depend on donated books from friends, volunteers, and members to keep the shelves well supplied. We can use your surplus garden books for this program which helps support our volunteer activities. Books can be dropped off at the Ruby C. McSwain Education Center.
