Director's Note

By Mark Weathington, Director

Spring is finally here and boy did it take its time. This has been a fun spring for me since I’m in a new house and only began planting last fall. Like most everyone else's landscape, both my garden and the Arboretum took a bit of a beating this winter, and we'll have plenty of space for some new things. Raulston Blooms! will have plenty of plants to fill in all the holes left by a very cold winter.
Despite the chilly weather, we've been quite busy especially with school tours. Many hundreds of children have been visiting and participating in the educational opportunities we offer. For some, the hubbub of 80 3rd graders in the garden can be a bit overwhelming but it is all worth it if we can get a few budding horticulturists excited about the plants around them.

See you in the garden.

Spring Event for Hobbyists

By Sarah Alford, Programs and Education Assistant
This month, we're offering three fun events that focus on exploring the garden from new angles. On Saturday, April 14, Mary Doherty will offer a hands-on workshop titled Exploring iPhone Photography in the garden. iPhone enthusiasts will enjoy exploring new techniques to capture the garden's springtime glory as well as learning how to process those photographs with a photograph editing app. Registration is open online .

For those of you who prefer a more active experience, join Patrick Brandt of Piedmont Tree Climbing on Saturday, April 28 for a chance to scale one of the JCRA's majestic oak trees ! This event is open to youth and adults and because no previous experience is necessary it's a great opportunity to get a group together and learn a new skill! Patrick will provide gear and lead participants through an informative lecture on how to climb safely before guiding the new climbers up into the treetops! Join us and register today ! We're offering a second day of tree climbs on Saturday, May 26 as well.

Also on Saturday, April 28, Pam Chance will facilitate a day of self-care , highlighting horticulture therapy’s use of plants in order to benefit well-being. Participants in this workshop will learn about the myriad of ways gardening can have a positive impact on our mental, emotional, physical, spiritual and intellectual selves through a talk on the history of horticulture therapy and a variety of individualized activities that center around creative ways to use gardening as self-care. All participants will leave feeling refreshed and full of new creative energy to apply to their gardens. Make sure to schedule time for yourself and register online today !
Tea Olive, Cold Hardier than You Might Think

By Douglas Ruhren, Gardens Manager

This winter has shown that cultivars of Osmanthus fragrans vary in their cold hardiness. A few are now nearly leafless, most others unfazed by single digits. A recommendation to stick very tender cuttings had me out in the Arboretum visiting each plant.

For four decades, I considered Osmanthus fragrans , the tea olive, to be a zone eight plant which we gardeners struggled to grow in zone 7. A struggle deemed worthy for there could hardly be a finer perfume than that of its flowers. A fragrance made all that much sweeter for it came in late summer with the promise of the fairer weather of autumn. It did not matter if a cold winter had ravaged the plant for even a few flowers could perfume a whole garden, a few more, a whole neighborhood.

It seems as if the Osmanthus fragrans grown by generations of gardeners is much less cold hardy than more recently introduced cultivars. It is possible, perhaps even likely, that all of it was one clone. ‘Fudingzhu’ is the cultivar in the Arboretum most like this old one, and it is now nearly leafless. The following cultivars had no damage: 'Apricot Echo', 'Apricot Gold' (photograph above), 'Beni Kin Mokusei', 'Butter Yello'’, 'Da Hong Zhu Sha Gui', 'Live Oak Gold', 'New Red', 'Orange Supreme', 'Thunbergii', and ‘Zao Hong Don Gui’ and O. fragrans f. aurantiacus . The downside of being cold hardy is that some of these plants are now about 15' tall and wide or more. Anyone up to breeding a dwarf tea olive? There are about five additional cultivars in the JCRA nursery waiting to go in the ground and test.

According to The Flora of China , this species occurs in Guizhou, Sichuan, and Yunnan provinces, nearly 1,000 miles from north to south, a range I imagine from about a moderate temperate climate like Raleigh to subtropical, so this species might vary in cold hardiness in the wild. Its common name derives from the use of its flowers to perfume tea and that it is in the olive family, the Oleaceae, along with lilac, forsythia, privet, and others.
Classes to Improve Your Gardening Know-how

By Sarah Alford, Programs and Education Assistant 

While our hobby classes will offer a relaxing way to interact with the garden this month, we also are offering several classes to stretch your mental muscles! DNA Barcoding of plants may sound like something out of a science fiction novel, but as Andrew Pais (our database and plant records coordinator) will share on Tuesday, April 10, this method is in use at the JCRA and is extremely helpful in verifying the identity of plants. Traditional methods for identifying plants make use of the visible similarities and differences between plants, but DNA barcoding focuses on what is invisible to the naked eye and uses DNA sequencing technology to describe the evolutionary history of these plants. The intricacies of this method open exciting doors for the identification of previously unknown plants, and we'd love to have you come out and learn more!

Implementing a fresh design for your garden can end in a major headache if not planned for properly! Join artist, educator, and landscape designer Preston Montague on Saturday, April 28 for a class on improving curb appeal through foundation plantings . In this fourth class in the Landscape Potential series, Preston will introduce the strategies professional landscapers use when planning and implementing new designs as well as tips for successful planting of recommended species. The other Landscape Potential classes are not prerequisites for this program. As part of registration , you can also choose to sign up for a practicum session with Preston. These one-on-ones provide the perfect opportunity to get a professional's advice on the specific challenges your home landscape faces! Space is limited, so sign up today.
Nancy Doubrava

By Mark Weathington, Director
A major part of the mission of the JCRA is to educate and engage the public about plants. Few people have had such a major impact on this part of the mission over the past 18 years as Nancy Doubrava. Nancy began her association with J. C. Raulston, Ph.D., as one of his graduate students studying roadside ornamental plantings. Some years later in 2000, Nancy returned to the JCRA as a interpretive specialist and soon after began the monumental task of labeling the collection. 
Over the years, Nancy has helped make the Arboretum one of the best-labeled gardens in the country. She was also responsible for the educational signage around the garden, seasonal tour pamphlets, special event posters, and way-finding. Her work was often one of the few ways we reached and engaged the casual visitor and was certainly critical to communicating to our active visitors.
Nancy retired in March leaving a high standard for everyone who will follow in her footsteps. All of the JCRA family staff, volunteers, and members thank her for her hard work and hope to see her often around the Arboretum.
