The Arnold Arboretum is a public-private partnership of the City of Boston and Harvard University, but derives all funding from past and present philanthropy. Founded through the bequests of farmer Benjamin Bussey and whaling merchant James Arnold, the Arboretum blossomed through important contributions like the Larz Anderson Bonsai Collection and the extensive book collections of Founding Director Charles Sprague Sargent in our Library and Archives. Sargent also solicited friends and neighbors to support the institution as members of The Friends of the Arnold Arboretum. Contemporary funds created by Arboretum supporters sustain such programs as our Field Studies Experiences for schoolchildren, opportunities for student scientists, and our summer internships in horticulture. Help sustain our mission at the end of our fiscal year by donating to the annual fund by June 30.
