The American Chestnut: When Will It Flourish Again?

9:00am to 12:30pm


Weld Hill Research Building

The American chestnut could be the first tree ever restored to its native forest after suffering from a devastating airborne blight in the early 1900s that killed billions of trees.

Join us for a thought-provoking gathering as experts share perspectives on the history of American chestnut (Castanea dentata), its significance as a forest species, and subsequent decimation by an invasive blight pathogen, Cryphonectria parasitica. Ongoing research in blight tolerance and the addition of blight-tolerant genes are the prognosis for this tree’s future....

Simple after-care will be required until planting out in springtime. Registrants will need to sign an Assumption of Risk and Release in order to participate in this class.

Botany Blast: Triggers in Trees

6:30pm to 7:45pm


Hunnewell Building
To understand how a tree develops, it is helpful to understand what leads to change. In this Botany Blast, Jake Grossman, a plant ecophysiologist and community ecologist, will explain what’s happening inside a tree that makes leaf buds break, initiates flowering or the dropping of leaves. Bring your questions and delve into the signals and processes that trigger events in trees. Botany Blasts are created for the Arboretum’s Tree Spotter Volunteers to help them better understand the phenological events they are recording in the landscape, but all are welcome to participate.

Native Bees in the Hood

In the second part of the workshop, we’ll focus on native bee decline and conservation, and learn answers to common questions such as: Why are bees dying? Do all bees need saving?

Do Your Garden Plants Have a Backstory?

7:00pm to 8:15pm


Hunnewell Building
Museums assign value to their collections by understanding each piece’s backstory – for instance, where did it come from, who created/collected it, what does it represent, what feeling does it elicit from a visitor? The plants in our own gardens can and should do the same, but too often have become generic and mundane because we have forgotten their backstories. Perhaps even worse, we may be losing our own personal connections to what we grow. Michael Dosmann will provide his own perspective on how to re-engage with our garden plants in ways that make it personal.
