As a member, you are part of a strong community of like-minded people who want to help the Arnold Arboretum flourish now and in the future. You are part of our 150 years of special relationships between plants and people—a community that includes plant and environmental scientists, science educators, school children and families, walkers and runners, and nature enthusiasts everywhere.
As a nonprofit organization that is free and open to the public every day of the year, we rely on the thoughtfulness and generosity of our contributors. Our strength derives from the support of members like you who enjoy the Arboretum for free (both in person and online), yet contribute annually to ensure the Arboretum stays vibrant and dynamic. Individuals, families, and institutions can join or renew their membership at any level by simply following the links below to our online membership form.
Please note our membership levels changed in May 2022 after more than 25 years to better align costs and revenue. Please select the membership level below that makes sense for you—every dollar contributed helps advance our work and benefits all visitors. If you would like to make a donation that is different from or in addition to the membership levels, we welcome you to make a gift via our donation page.
