Tree Mobs™

Peter Del Tredici (center), the Arnold Arboretum's senior research scientist, discusses the Stewartia collection, which dates from 1918. “You can come here and see these plants, but you don’t know anything about them. You could hold your cell phone up [to the bar codes on the signs posted by many plants]. But it’s better to have someone tell you,” said Del Tredici.

Tree Mobs are being offered virtually via Zoom until we can meet in the landscape again. Upcoming Tree Mobs are listed on the Events page and you can sign up below to receive email notifications.

What’s a Tree Mob™?

Tree Mobs are interactions with scientists or other specialists at the Arnold Arboretum, and provide another pathway to enjoy and learn in the landscape. Experts share little-known facts about our living plant collection, its relevance today, and its importance to future generations. A Tree Mob may attract a small group or a large gathering—we won’t know until it takes place. Join us in the landscape and discover something new.

What can I expect?

Plan to spend approximately 30 minutes learning about an interesting component of our collection. You can then continue your exploration of the Arnold Arboretum on your own. Tree Mobs are time, date, and location specific.

How does it work?

We will communicate about Tree Mobs by various means (see below). Using mobile technologies, such as a smartphone with location-awareness enabled, you will be able to navigate to the event location. You can also view and print a map we will provide with the day’s Tree Mob location on our website. With directions in hand, proceed to the designated meeting place to participate in our experiment for spontaneous learning.

How can I be notified?
