Rooted in history.

The Arnold Arboretum sits on land long inhabited by Indigenous Peoples, most recently the Massachusett Tribe, and on property purchased with wealth from goods produced by enslaved persons.

Free and open every day.

We are committed to the Olmstedian principle that everyone is entitled to open space, so our gates are open to everyone, every day, free of charge.

Funded by our community.

The Arnold Arboretum has been funded by the generosity of the supporting public since our founding in 1872. Give today and continue that legacy.
