The Garden Conservancy’s Open Days program continues July 13 in Washington County, Rhode Island, with Thompson’s Corner in Westerly. This garden has evolved over the last twenty years. It contains more than 25 species of trees, including a London Plane tree which was planted to commemorate Westerly’s Tercentenary in 1969. There is a grove of paw paw trees started from seed and a ginkgo tree which is a descends from a tree in Westerly’s Wilcox Park, an arboretum. Although less than three-quarters of an acre in a village setting, there are two water features, a summer kitchen, a small boat barn, and an outhouse which is now the world’s smallest “she shed” on the grounds of this antique farmhouse. The emphasis has been on using natives to create a naturalistic settling. The garden is organic and toxin free. Two sessions, 10 – 1 and 1 – 4. $5 for Garden Conservancy members, $10 for nonmembers.
