Hemlock, Tsuga canadensis, is an eastern Hemlock. It's a medium sized conifer that likes full sun or partial shade. It grows 20-50ft high and wide. It's a multi-stemmed tree with pendent or arching sprays of small, dark green, silver-backed leaves. Cones are freely borne and ripen to brown. It will tolerate most soils, but definitely dislikes any dry soils.
