Bring a bagged lunch to the Berkshire Botanical Gardens on Saturday, March 20 for a fascinating illustrated lecture, beginning at 10:00 am. Where to begin with hosta and daylilies? Suitable for both sun and shade gardens, these low maintenance, drought tolerant plants offer much for both the beginner and the advanced gardener. Learn about these rugged and important garden stalwarts. Consider varieties, siting, cultivation, health care, diseases, design possibilities and companion plants for these poplular and well loved classics. Barbara Provest manages the New England Daylily Society Display Garden at Elm Bank in Wellesley, and takes care of 650+ daylilies there. Her garden is an official American Hemerocallis Society Display Garden with 1,136 cultivars. Meg and Jim Dalton are avid hosta collectors and members of the Tri-State Hosta, Upstate New York Hosta, and American Hosta Societies. Members of BBG will be charged $20, non members $25. For directions, log on to www.berkshirebotanical.org.
