There are three gardens at the Munroe Tavern, planted and maintained by the Lexington Field and Garden Club. The Garden of Colonial Flowers contains simple, unimproved, open-pollinated flower species grown by Boston gardeners in the mid-to-late 1700s. A recently restored Rose Garden features species brought from Spain or the Mideast generations ago. The Wildflower or Native Plant Garden contains a large trillium collection, as well as many different plants, ferns, and shrubs that bloom during the spring. The gardens add to the story being told at the tavern, providing plantings of historic interest and natural beauty.
