TREES & Plants

Eastern hemlock

One of the more shade-tolerant evergreens, the eastern hemlock has many uses, as a specimen, sheared as a hedge, or planted for screening.  Native to the eastern U.S., the hemlock resembles a large Christmas tree with its broadly pyramidal, pendulous branches and fine, dark green needles on widely spaced branches that give it a delicate, lacy feel.  The tree even has abundant, brown cones that hang from branches like small ornaments.
