!The Tree
The Western Hemlock is an important forest tree of the Northwest. It is 125 to 160 feet tall with a tall. clean, smooth-looking trunk one and a half to four feet in diameter. The bark of the younger large branches is thin, scaly and a dark russet brown, while on the large mature trees the bark is up to one and a half inches thick, hard, dark reddish brown and deeply furrowed. The small branchlets droop gracefully. The needles are one-quarter to seven eighths inch long, ﬂat, narrow, grooved on the upper surface, rounded on the end, glossy and a deep yellowish green color. They remain on the tree from three to six years. The small pendant cones which are almost twice as large as those of Eastern Hemlock are three-quarters to one and a quarter inches long, are oblong-ovoid, have thin downy scales and are a reddish clay-brown color when the cones are open. This Hemlock is one of four hemlock species in the United States. The Western Hemlock was chosen the ofﬁcial State tree of Washington in March, 1947.
