Hemlock is used primarily as a construction timber, and is also used in boxes, pallets, crates and plywood.
In addition to its lumber, Eastern Hemlock is also known for its ornamental value. Eastern Hemlock is also the state tree of Pennsylvania. Currently, the species is threatened by the hemlock woolly adelgid, a non-native insect that kills infested trees.
Compared to Western Hemlock, Eastern Hemlock generally has wider growth rings, though both species can have tightly spaced rings.
