Coastal Maine Botanical Gardens is a people’s garden, a grassroots effort that began as a casual conversation between friends and evolved into the largest botanical garden in New England. Located on more than 300 acres along the Mid-Coast, the Gardens is a true Maine experience. The mission of Coastal Maine Botanical Gardens is to inspire meaningful connections among people, plants, and nature through horticulture, education, and research. Explore our more than 300 acres of gardens and natural spaces, from the Native Butterfly and Moth House to the Bibby and Harold Alfond Children’s Garden or Giles Rhododendron and Perennial Garden.
