Tree Mob!™: Zooming in on Tree Swallows

This video is about tree swallows at the Arnold Arboretum in Boston, Massachusetts and was recorded on May 20, 2020. Karla Noboa, a NestWatch volunteer and founder of the Feminist Bird Club, Boston Chapter, shares her experiences in monitoring nesting boxes over the course of the breeding season. She speaks about tree swallows and chickadees, their preferred habitats, and diets.


Flower Power: How Pollinators Get What They Want from Plants

In honor of Pollinator Week at the Arnold Arboretum, Dr. Robin Hopkins, John L. Loeb Associate Professor of the Natural Sciences, reveals various strategies flowers use to manipulate pollinators to do their bidding. Through a series of flower dissections, Dr. Hopkins guides us to understand flower morphology, and how different floral traits – known as pollinator syndromes – can help predict the type of pollinator that will aid that flower to set seed. Witness the results of millions of years of co-evolution between plants and pollinators, and use that knowledge to harness flower power in your home gardens!


Silk Moths in the Arnold Arboretum

Arnold Arboretum volunteer, Bob Mayer, has been raising and breeding four species of silk moths on site at the Arnold Arboretum to discover if any of the four species native to Eastern Massachusetts – cecropia, polyphemus, promethea and luna moths – can be found at the Arnold Arboretum.


Tree Mob™: Zooming in on Spruce Cones

William (Ned) Friedman, Director of the Arnold Arboretum of Harvard University and Arnold Professor of Organismic and Evolutionary Biology at Harvard University, speaks about coning and reproduction in spruce trees. This Tree Mob™ was recorded in the Arnold Arboretum’s conifer collection and was offered virtually to audiences via Zoom Meeting on May 8, 2020.


Welcome back, Bonsai!

Join Steve Schneider, the Director of Operations and Public Programs, for the first installment in a series of behind the scenes videos focused on the Arnold Arboretum’s Bonsai & Penjing Collection. In this video, learn about the cold storage facilities, where the dwarfed plants spend their quiet winter months. Then watch as one of the largest specimens, a compact hinoki cypress, Chamaecyparis obtusa ‘Chabo-hiba’ is welcomed into the pavilion for the growing season.

Check back for additional videos focusing on repotting and highlights on some of the beautiful specimens.

Among the oldest surviving bonsai in America, the Bonsai & Penjing Collection is a beloved treasure of the Arnold Arboretum and Boston. While the plants that currently make up the Collection are not the oldest dwarfed plants in the United States, they have been under cultivation longer than any other examples currently growing in North America—with the exception of three plants at the Brooklyn Botanic Garden that were imported in 1911.

In order to follow COVID-19 safety guidelines (Spring 2020), the Bonsai & Penjing Pavilion is closed to the public. Check the Arboretum website for updates on the reopening of the pavilion, or call 617.524.1718.
