Annual Appeal gift amounts and their impact on the operations of the Arnold Arboretum

The Arnold Arboretum is a partnership of Harvard University and the City of Boston, yet our critical work in horticulture, research, and education is funded almost entirely through present and past philanthropy. In Fiscal Year 2023, a full 17% of the Arnold Arboretum’s operating budget came from current gifts and memberships. We need your financial help to keep our landscape vibrant and to activate our research and educational mission both in Boston and around the globe.

Read our 2023 Annual Appeal letter from Darcy Foster, Individual Giving Associate.

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

If you would like to discuss a donation to the Arboretum’s annual appeal or any other aspect of our fundraising, please contact Tanya M. Holton, Director of Institutional Advancement at 617.384.5043 or
