The Dr. John Green Society, named for the first president of the Worcester County Horticultural Society, is the preeminent donor community of Tower Hill Botanic Garden and provides our most loyal members the opportunity to make a deeper connection with – and contribution to – the mission of the Garden.

By becoming a member of the John Green Society with an unrestricted gift of $1,250 or more, you join other committed members who take a leadership role in supporting Tower Hill. Our John Green Society members form the foundation of our annual giving program and provide critical resources to sustain our operations throughout the year. These funds allow us to keep our gardens looking beautiful, underwrite free educational programs, grow our horticultural collections, help us to maintain our buildings and so much more.  

Members are invited to participate in exclusive events that provide unique access to the Garden and its leadership, and with the opportunity to be a part of a fun and dynamic community of philanthropists.
