Tree Mob: The Trees that Shaped the Seas

September 5, 2025 @ 12:00 pm – 12:45 pm
Entrance to Conifer Path on Valley Rd 8V2F+2QQ, Boston

As a lead-up to our Haunted Botany performance piece about the colonial histories of Eastern White Pine, join Materials Science Professor Lorna Gibson for a Tree Mob on tree species that were used to build colonial ships. From dense oak hulls designed to withstand cannonballs, to tall, straight masts made out of towering pine trees, each tree species was selected for its own unique strengths– both in the forest and at sea.

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.
