The Ecological Landscaping Association, New England Wildflower Society, Arnold Arboretum of Harvard University, Massachusetts Audubon Drumlin Farm, and Tower Hill Botanic Gardens will co-sponsor Spring Wildflowers of the Northeast: A Natural History, with author Carol Gracie, on Sunday, April 28, from 1:30 – 3:30 at Garden in the Woods in Framingham. The wildflowers that brighten our woodlands in spring are more than just a delight for the eye and a lift for the winter-weary spirit. Each has a role in the environment, with often interesting interactions with pollinators and seed dispersers. Topics will include adaptations for early blooming, medicinal and other uses, the origin of wildflower names, pollination and seed dispersal, and the latest scientific research on the ecology of these beautiful plants. Following the lecture and book signing, enjoy an optional docent-led walk through Garden in the Woods in its early spring glory. $15 for members of a sponsoring organization, $18 for nonmembers. Register by calling 617-436-5838, or visit www.ecolandscaping.org.
