This deciduous coniferous tree grows to 25–30 meters tall with a trunk reaching a meter in diameter at breast high, with gray to gray-brown bark with flaking and scaly fissured bark. Its leaves are needle-like, dark-green, 1.5–3 cm long and 1 cm wide. The reddish purple or violet cones mature to light brown, sometimes tinged with purple, and range from 18 to 25 mm long. Pollination occurs in May with seeds maturing in September-October. It grows in mountains and on moist slopes and in swamps. The timber has many uses in construction and for wood fiber. The trunk is used to produce resin while the bark is used for tannins.[4]
