Visit two private gardens on Sunday, August 22, from 10 – 3, with Tower Hill Botanic Garden. Brigham Hill Farm in North Grafton is the home of Shirley and Peter Williams. The spectacular new vegetable garden will be lush with summer crops, and the water garden will provide a sense of coolness during the month of august. Lush lawns, enormous shade trees, and many flowery nooks and crannies complete the scene. At Green Hill in Boylston, the home of Sarah and Allen Berry, you will find an extraordinary collection of rare and unusual trees and shrubs. The great expanse of fields should be in the peak of summer bloom. Share in the infectious enthusiasm of the owner and creator. $15 for Tower Hill members, $20 for nonmembers. To register, log on to www.towerhillbg.org.
