Saturday, August 6, 1:00 pm – 3:00 pm – Epimediums: Not Just a Ground Cover

Known by many as the ultimate groundcover for dry shade, the increased availability of the useful genus epimedium is expanding its role in the garden. The delicate beauty that these plants and their flowers possess belies their surprisingly tough, long-lasting nature and their ability to perform in the ornamental shade border. As Karen Perkins shares the history and culture of this up-and-coming genus, from its growth habit and propagation to management of pests and diseases and possible planting combinations, attendees will be inspired to experiment with the ever increasing selection of these shade-loving plants. Plants will also be available for sale after the talk. The event, co-sponsored by the Berkshire Botanical Garden and the Berkshire Chapter of the North American Rock Garden Society, will take place Saturday, August 6 at the BBG. Sponsor members $15, nonmembers $20. Register online at

Karen Perkins is owner of Garden Vision Epimediums, a mail-order nursery offering 160 species and varieties of epimedium along with other choice shade perennials. She lectures frequently at botanic gardens throughout New England.

Friday, August 19 – Sunday, August 21 – In The Garden Weekend

Find your green thumb at The Homestead Resort’s In The Garden weekend over the dates of August 19-21, 2016. You will learn time-honored gardening tips from top professionals and enjoy your choice of hands-on garden themed classes amid the resort’s breathtaking scenery. Speakers include Craig LeHoullier, gardener, author and educator, Mark Weathington, Director of the JC Raulston Arboretum at NC State University and Andre Viette, Horticulturalist, author and lecturer.

Possessing a PhD in chemistry, Craig LeHoullier’s professional career involved various positions in a major pharmaceutical company. Craig’s passion for tomatoes in particular exploded after joining the Seed Savers Exchange in 1986, and all gardens since focus on open pollinated (non-hybrid) varieties, in a wide range of colors, sizes and flavors. He is responsible for naming, developing and introducing many varieties, such as Cherokee Purple and Lucky Cross, and has been co-leading a unique all-volunteer project to create new dwarf-growing varieties. The project is responsible for 25 new tomatoes available through a variety of seed companies, particularly valuable for space-constrained gardeners who wish to grow wonderful tomatoes on decks or patios.

Mark Weathington is the Director of the JC Raulston Arboretum at NC State University where he is passionate in his work to connect people with plants. His career in public horticulture has also included the Norfolk Botanical Garden where he served as Director of Horticulture and the Atlanta Botanical Garden as a horticulturist. Mark travels extensively searching for new plants to diversify the American landscape and lecturing on a variety of topics in horticulture to further the JC Raulston Arboretum’s vision of “Planning and Planting a Better World.”  Mark is currently writing Growing the Southeast Garden, a modern guide to gardening in the southeast, for Timber Press.

Horticulturist, author and lecturer, Andre Viette earned his Biological Science Certificate at The State University of New York at Farmingdale, and is a graduate of The School of Floriculture of Cornell University. Mr. Viette hosts his own talk show entitled “In the Garden” and has written several books including Beautiful Roses Made Easy, Mid-Atlantic Gardener’s Guide, and his newest book Mid-Atlantic Getting Started Garden Guide. He has developed André Viette Farm and Nursery in Fishersville, Virginia, which grows over 3,000 varieties of perennials for the sun and shade.

Wednesday, July 27, 1:00 pm – 5:00 pm – What Role do “Nativars” Play in an Ecological Landscape?

As interest increases in native plants for ecological landscapes, growers and nurseries are meeting the demand through increased production of native plant cultivars (nativars) and through asexual propagation methods like cuttings, grafting, and tissue culture.

While asexual propagation is perhaps the quickest way to produce large quantities of plants in order to meet demand, a landscape composed entirely of clonal plants (even if they are native) does not offer the same level of ecosystem services as a genetically diverse landscape grown from locally-sourced seed. Co-sponsored by ELA and New England Wild Flower Society, this program is intended to raise awareness of the many aspects of this important topic. The audience for this event will be landscape designers, landscape architects, conservation and restoration specialists, growers, and others in the landscape field. We hope that this discussion will reveal current research into the ecological value of nativars and other asexually propagated native plant species, and address the challenges of meeting the demand for genetically diverse native landscapes.

In the midst of many opinions, this  July 27 ELA workshop at Garden in the Woods brings together several experts on the topic to bring clarity and guidance on the topic.

Presenters and Panelists:

Cayte McDonough is the Nursery Production Manager for New England Wild Flower Society’s Nasami Farm Native Plant Nursery based in Whately, MA. For the past 15 years she has worked to propagate, cultivate, understand, and promote New England native plants. McDonough and her colleagues collect seeds in the wild with permission from landowners. They collect from large populations to ensure genetic diversity and limit their collections to 20 percent of the available seed to minimize the impact on the population. She also enjoys learning about native pollinators and supporting local farmers.

Michael Piantedosi is the Seed Bank Coordinator of New England Wild Flower Society and is currently working with Seeds of Success (SOS), a native seed collection program led by the Bureau of Land Management. SOS collects wild land native seed for research, development, germplasm conservation and ecosystem restoration. The ultimate goal is to ensure the availability of genetically rich, regionally adapted native plant materials to restore, rehabilitate and stabilize lands in the United States.

Mark Richardson oversees the New England Wildflower Society’s botanic garden, Garden in the Woods in Framingham, Massachusetts and its native plant nursery operation, Nasami Farm in Whately, Massachusetts. He studied ornamental horticulture at the University of Rhode Island and helped run a mid-sized ornamental plant nursery before finding his true passion in public horticulture. He led undergraduate programs at Longwood Gardens, overhauled the curriculum of the Professional Gardener Program, and oversaw adult education at Brookside Gardens. In 2013, Mr. Richardson assisted with the development of the first comprehensive master plan for Garden in the Woods. He holds an MS from the University of Delaware’s Longwood Graduate Program.

Peter van Berkum, along with his wife Leslie, started Van Berkum Nursery (VBN) in 1986. VBN is a wholesale perennial nursery specializing in natives, shade perennials, and Wicked Ruggeds – plants that perform well and last a long time in New England landscapes. Peter has a degree in Plant Science from the University of New Hampshire, spent a year studying horticulture in the Netherlands, and worked at several nurseries before starting VBN. He is a past president of the New Hampshire Plant Growers Association, as well as a founding member of the New Hampshire Horticulture Endowment. He and his wife were recipients of the Massachusetts Horticulture Societies Silver Medal, and Peter was the Perennial Plant Association’s Grower of the Year in 2013.

Laney Widener is the Botanical Coordinator at the New England Wild Flower Society with a background and research on plant genetic differences.

Annie White is a Horticultural Researcher at the University of Vermont and owner of NECTAR Landscape Design Studio & Consulting. Annie has a PhD in Plant & Soil Science from the University of Vermont and a MS in Landscape Architecture from the University of Wisconsin-Madison. For years, Annie worked as an ecological landscape designer and continually saw native cultivars being substituted for native species in her designs. Recognizing a lack of research to support this, she began researching the topic herself as a PhD student. Using replicated research methods, Annie has evaluated about 20 native cultivars in comparison to the native species for pollinator preference, floral abundance, bloom duration, and hardiness. Her research was funded by a SARE Partnership Grant and the New Hampshire Horticultural Endowment.
