JC Raulston Arboretum e-Update

January 2006

In This Issue

From the Director

Greetings from the JC Raulston Arboretum. In the last month, I've moved my belongings from the office in Kilgore Hall on campus, and now I'm relatively settled into the office at the JCRA. I want to thank the JCRA staff for all of their efforts in keeping the programs of the JCRA moving ahead in the past year, in spite of the vacancies in many critical positions. They have done a remarkable job in 2005. Their efforts and dedication have certainly made my transition easier. I also want to take this opportunity to sincerely thank Jon Roethling and Todd Lasseigne, past JCRA research technician and JCRA assistant director, respectively, for all of their contributions to the JCRA during their tenure here. The programs and collections of the JCRA benefited greatly from their commitment to and passion for the JCRA. All of the staff and I are excited about the opportunities for enhancing the gardens and the programs at the JCRA in 2006 and the years ahead. Chris Glenn has done a great job putting together a wonderful offering of lectures and workshops for spring 2006. See below for more details on some of these events. We plan to increase the number of lectures, workshops, and other special events at the JCRA, so keep your eyes open for more details on these events as they become available. Also, we have a special JCRA 30th anniversary symposium planned for September 22, 23, and 24, 2006, with a lineup of incredible speakers of national and international prominence. More details will be forthcoming in our next JCRA Newsletter, but save these dates on your calendar. Lastly, I want to thank all of you who have so kindly welcomed me to the JCRA. Your expressions of support for me, the staff, and for the gardens and programs of the JCRA are greatly appreciated. The Arboretum is a special place to me, as it is for all of you. I'm heartened and grateful for the offers of assistance that I have have received, and I look forward to meeting and getting to know each of you. I'm honored to have the opportunity to be the director of the JCRA, and with your help, passion, and support, I look forward to charting a future course for YOUR JC Raulston Arboretum. Take care, and please drop in and say hello the next time you are at the JCRA. Visit often. – Denny Werner, Director

New JCRA Staff Members!

Tim Alderton and Layne SnellingWe are pleased to welcome two new employees to the JCRA. Tim Alderton has filled the vacant JCRA research technician position. Tim is a native of western Pennsylvania, and has a degree from Pennsylvania State University in Horticulture. Tim has been employed at Plant Delight's Nursery here in Raleigh for the past year, and we are pleased that he has decided to join the staff of the JCRA. Tim will be involved in care and maintenance of the the JCRA grounds and plantings, assisting with propagation and culture of plant materials for our fall plant give-away and Connoisseur Plant programs, working with our curators and volunteers, and all of the other jobs that spring up here in the JCRA.

Many of you already know Layne Snelling, who has worked as my research technician in the ornamentals breeding program since the mid-1990s. Prior to his involvement with the ornamentals breeding program, Layne worked for many years with Eric Hinesley, Ph.D., in the Department of Horticultural Science. Eric's program focused on propagation, culture, and management of Fraser fir. Now that the Cercis, Buddleja, and Stokesia breeding efforts are part of the programs of the JCRA, Layne has joined the JCRA staff as the individual responsible for the coordination and execution of the plant breeding and improvement efforts of the JCRA.

Please welcome both Tim and Layne to the JCRA family! – Denny Werner, Director

Upcoming Workshops

As promised in Denny's message above, the Arboretum will be offering more programs this year including some great workshops. We are proud to announce the following workshops for spring 2006:

"Tissue Culture of Phalaenopsis Orchid Seed and Seedlings" – February 25, 2006 (Saturday) – 9:00 AM-1:00 PM – $30.00 (members only)

Workshop participants will learn about orchid sexual reproduction and seed biology. Participants will learn and engage in the techniques of orchid seed sterilization, and culture of seeds of Phalaenopsis orchids on artificial growing media under aseptic (sterile) conditions. Participants will also subculture five-month-old Phalaenopsis seedlings onto fresh media, and transfer older seedlings from sterile culture conditions into pots for greenhouse growing. Participants can take home young Phalaenopsis seedlings.

"The Art of Espalier" – April 15, 2006 (Saturday) – 10:00 AM-12:00 PM – $25.00 (members only)

Lee Calhoun, a resident of Pittsboro, North Carolina, developed a passion for collecting and preserving antique southern apple varieties. His living collection includes over two hundred varieties, all grown in his backyard. To accommodate this impressive collection, Lee propagated all varieties on dwarfing apple rootstock, and established them on a trellis system using the techniques of espalier. Lee will share with participants the history of his impressive collection, and describe and demonstrate the various espalier training forms he has used. Although Lee's expertise is in using the art of espalier for maintaining his apple variety collection, the concepts, principles, and techniques that he will share are applicable to espalier of many woody ornamental plants. The seasonal timing of this workshop will correspond to the time of full bloom for much of his collection, so expect to revel in the beauty of this remarkable collection in flower.

Complete details for these workshops (and all of our other programs too) are available on our Web site in our Calendar of Events section. – Chris Glenn, Programs and Education Coordinator and Denny Werner, Director

January Calendar

Friends of the Arboretum Lecture – January 12, 2006 (Thursday) – 7:30 PM – Free for members, $5.00 for non members

"Cercis and Buddleja Breeding Efforts at the JCRA" presented by Denny Werner, Director– Our native redbud, Cercis canadensis, demonstrates a remarkable range of variability in traits such as growth habit, plant size, leaf and flower color, flower morphology, and leaf shape. Denny will discuss the current status of his breeding work aimed at exploiting this variation for developing new cultivars of this popular landscape plant. New advances in redbud propagation technology currently being developed in the nursery industry, and what impact these technologies may have on potential performance of redbud in the landscape, will also be discussed. Denny will also discuss his breeding efforts in Buddleja, focusing on sterility, compact growth habit, and extending the range of flower color.

Friends of the Arboretum Lecture – January 26, 2006 (Thursday) – 7:30 PM – Free for members, $5.00 for non members

"Some Like It Hot: Sizzling Tropical Plants for Containers and Borders" presented by Pam Baggett, Singing Springs Nursery, Cedar Grove, North Carolina – Reveling in our hot, humid summers and mild autumn months, tropical and sub-tropical plants perform beautifully in North Carolina gardens, providing months of flowers or colorful foliage (or both!) and growing vigorously right up until fall frost. From tiny jewel-like cupheas to towering bananas, easy-to-grow tropicals stretch the textural palette to its limits, while also pushing color boundaries with their often incendiary tones. Singing Springs Nursery owner Pam Baggett shows you the best tender and hardy tropicals for borders and containers, and offers insights on incorporating them into your garden.
