Canadian hemlock (Tsuga canadensis), also called Eastern hemlock or hemlock spruce, is a slow-growing, long-lived tree which, unlike many trees, grows well in shade. It may take 250 to 300 years to reach maturity and may live 800 years or more. A tree measuring 193 cm (76 in) in d.b.h. and 53.3 m (175 ft) tall is among the largest recorded. Hemlock bark was once the source of tannin for the leather industry, but the wood is now important to the pulp and paper industry. Many species of wildlife benefit from the excellent habitat that a dense stand of hemlock provides. This tree also ranks high for ornamental planting.

Canadian Hemlock
Canadian Hemlock (Tsuga canadensis)
The Canadian Hemlock is also called the Eastern Hemlock. These Hemlocks grow about ½ to 1 foot a year. Their red-brown bark is scaly when the trees are young, and becomes deeply ridged with age. This tree often grows more than one trunk. Canadian Hemlock will keep its lower branches for many years making a prime candidate for a hedge. When it gets fairly old, it loses some lower branches, but by then it is not worth keeping as a hedge anyway.
Hemlock leaves are actually very fine-textured needles. They are arranged along the twigs on a flat plane. Only about ¾ inch long, they are flat with rounded or slightly indented tips. They are dark green, with 2 whitish bands on their undersides. Needles are evergreen, lasting over a period of 3 to 5 years, some always being replaced.
These trees bear cones in May through early June. They are ¾ inch long and hang at branch tips, causing them to dip gently. Male cones are light yellow and female ones are light green. In the fall they turn brown, bearing seeds from September through January. Its annual growth rate is 12 to 18 inches. The Canadian Hemlock is the state tree of Pennsylvania.
