Arboretum Non-planted Trees, Shrubs and Vines
The Tamarck is our only conifer that looses all of its needles every fall and grows new ones in the spring.
The Arboretum has many habitats harbouring a wide variety of woody plants. While most are truly native, some of our "natural" plants are invasive species that have escaped from cultivation and have moved into our natural areas.
To learn more about our native tree species and see more photos of them, go to the Trees section of our website.
Freeman's Maples (a natural hybrid of Red and Silver Maples) dominate the swamp in The Arboretum's Wild Goose Woods.
Alternate-leaved Dogwood berries are an important food for wildlife.
If you would like to learn more about how to identify trees and shrubs, we offer a Tree Identification Workshop and a Shrub Identification Workshop. Click here for details.
