Description
The Eastern Hemlock is a large, long-lived evergreen conifer known for its graceful, drooping leader and soft, feathery foliage. The bark is dark brown to reddish-brown, deeply furrowed in older trees. It produces small, oblong cones measuring about half an inch to an inch long that hang from the branch tips. As a shade-tolerant climax species, it creates deep, dark forest canopies that regulate stream temperatures and provide critical wildlife cover.
Habitat
Cool, moist ravines, rocky slopes, streambanks, and dense, shaded northern forests with acidic soils
Native Range
Native to eastern North America, stretching from Nova Scotia and Minnesota south to the Appalachian Mountains to northern Georgia
