The Berkshire Botanical Garden, 5 West Stockbridge Road, West Stockbridge, continues its Horticulture in History series on Thursday, July 22 at 4 pm with a lecture, book sale and signing by author Judith Sumner. Beginning in prehistory, plants were known as the most reliable sources of essential medicines. Learn about traditional herbs and their many uses from ancient to modern times. Consider the best known herbal families, such as the mints and the mustards, and examine the basis for their efficacy. Traditional lore such as the Doctrine of Signatures, will provide historical context and breadth. This is an herbal adventure, spanning the medicinal botany practiced by the Greeks and Romans to the herb gardens of colonial America, herb use during wartime, herbs in the New England landscape, and modern herbal practices.

Judith Sumner is a popular lecturer for botanical and horticultural organizations, including the Arnold Arboretum, New York Botanical Garden, and Garden in the Woods. She is the author of several books including The Natural History of Medicinal Plants and American Household Botany.  To register ($20), log on to www.berkshirebotanical.org, or call 413-298-3926.
