The Arnold Arboretum is primarily funded through annual memberships, gifts, and endowments. We rely on your generosity to underwrite the care of our Olmsted-designed landscape and the stewardship of our extraordinary living collections. Your support is critical to everything we do, from Boston children’s education to conservation and world-class science.

Please note that our online gift form does not currently include functionality for “in memory of” or “in honor of” designations. For such gifts, we recommend sending your gift by mail using our printable donation form.

To make a gift by mail, complete our Printable Donation Form and mail to: The Arnold Arboretum of Harvard University, P.O. Box 419209, Boston, MA 02241-9209.

Though the Arnold Arboretum has an independent operating budget, it is an affiliate of Harvard University and shares the tax identification number for The President and Fellows of Harvard College: 04-2103580.

To transfer appreciated securities, please call 866-845-6596 or email
