Large colonial ship in a harbor

Tree Mob: The Trees that Shaped the Seas
Virtual Event

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.

Explorers Garden Tour

The Explorers Garden rests in a microclimate just below the summit of Bussey Hill. This nearly five-acre site provides ideal growing conditions for many species that have been challenging to grow in less protected areas of the Arboretum. As such, it has proven to be a perfect testing ground for plants collected in the expeditions of E. H. Wilson in the early 1900s to the NACPEC  (North America-China Plant Exploration Consortium) expeditions of our own time. Join docent Marie Herbert for a guided tour to learn more about some of the plants showcased in this special collection and to hear stories of the plant exploration expeditions that brought them to the Arboretum.

Haunted Botany: A Performance for a Forgotten Forest

The towering Eastern White Pine once dominated New England forests and served as an important symbol for Indigenous peoples, but the British Royal Navy’s thirst for tall, straight, trees to use as ship masts eventually led to the destruction of the vast majority of old growth pines in Massachusetts. Join Gwyneth Shanks and AB Brown for a performance piece highlighting Pinus strobus’s dramatic colonial history in which American settlers fought back against King George’s large-scale destruction of their forests, leading to direct resistance, riots, and eventually to the Boston Tea Party itself.

Spooky Plants: The Garden that Bites Back

As we ramp up for the spooky season of Halloween, join the Manager of Adult Programming and Events for a walk focused on the most sinister plants in the Arboretum’s collections.

Conservation in a Changing World

Part of the mission of the Arnold Arboretum is stewardship of the earth’s botanical diversity and its essential value to humankind. This one hour tour through the landscape, led by docent Vicki Amalfitano, will highlight important Arboretum historical conservation efforts that have preserved distinct native and exotic species, and current efforts in our living collections to mitigate habitat disruption and climate impact. Learn about plant expeditions to preserve species in the face of climate change and new pathogens, research initiatives, as well as the Arboretum’s green initiatives and local collaborations to improve our urban canopy.
