About Tsuga Canadensis
Canadian Hemlock usually grows to 40 to 70 feet tall in the wild, but can reach 100 feet tall. This species is noted for having the smallest needles and cones in the genus. Flat sprays of lacy evergreen foliage give this tree a graceful form. It has a conical crown of long, slender, horizontal branches often drooping down to the ground, and a slender, curved, and drooping leader. Gray-brown bark turns smooth, then scaly as it ages, older trees are red-brown with wide ridges and furrows. When cut or broken, purple streaks are obvious.

The bark was once a commercial source of tannin in the production of leather. These trees can easily be pruned and shaped and are common additions in landscaping Pioneers made tea from leafy twigs and brooms from the branches.
