Coastal Maine Botanical Gardens’ Maine Days welcomes Maine residents to visit at no cost over Memorial Day Weekend, Saturday through Monday, May 28-30.

Founded by Maine residents with a passion for gardens and the state’s magnificent coast and forests, the 105 Botanical Gardens Drive site in Boothbay is comprised of cultivated, formal gardens and natural landscapes that highlight natural history, habitats, botany, horticulture, and ecological connections while honoring Maine and its people, according to a news release from the gardens.

Endeavoring to make the gardens as accessible, inclusive, and relevant to the community as possible, each year during Maine Days state residents are invited to experience its gardens at no cost. Long a family tradition for many, this year’s event takes place because of Renys, another Maine institution.

Attendees also can visit the gardens’ larger-than-life environmental stewards, the giant trolls, here for their second season.

Advance registration for this event is required. Interested Maine residents should choose Maine Day tickets and note that the tickets are rain or shine.

At nearly 325 acres, Coastal Maine Botanical Gardens is the largest public garden in New England. It includes two miles of hiking trails and 19 acres of ornamental and themed gardens featuring native plants of Maine, a children’s garden, and a sensory garden.

The mission of the gardens is to inspire meaningful connections among people, plants, and nature through horticulture, education, and research.
