    Eastern hemlock (Tsuga canadensis), also called Canada 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 for 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; now the wood  is 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.
