Botanical Name

Plant Common Name

Canada Hemlock

General Description

Canada hemlock is a graceful evergreen tree that is useful for screening, hedges or as a feature plant in the yard. Its pyramidal shape is formed by pendulous branches lined with short, dark green needles. Small brown cones are formed in late summer and can be used in craft projects.

This eastern North America native is happiest in organic, well-drained but moist soil and can be sheared to a desired size or shape. Canada hemlock is intolerant of boggy soil, pollution and drying winds. Woolly adelgid can plague these trees and over the course of a few years will weaken and kill a mature specimen. A very beautiful weeping cultivar for a wall or hillside is known as 'Sargentii' or the Sargent's weeping hemlock.
