Eastern hemlock is a graceful evergreen tree with delicate, flat needles and drooping branches that create an elegant, layered appearance. This slow-growing conifer develops into a large specimen that provides year-round structure and screening in the landscape. It prefers cool, moist conditions and partial shade, making it ideal for woodland settings.

Growing Eastern Hemlock
