Pseudotsuga is native to the forests of China, Taiwan, Japan, Western North America, and Mexico. They are often used as Christmas trees because they tend not to shed their needles as much as others.
Douglas firs are evergreen coniferous trees that can grow to be incredibly tall with flat, needle-like leaves.

Propagate from seed. Sow in spring in containers outside.
Evergreen, fir like trees with pendulous cones with conspicuous protruding bracts and pointed, many-scaled buds. To 80 feet tall. Pseudotsuga grows best in full sun. Large specimen trees.
Well drained, deep, acidic to neutral soil. Blue types tolerate slightly alkaline soil.
Do not plant within 200 feet of Picea pungens (Colorado spruce) as they are alternate hosts for Cooley spruce gall aphids. Lesion nematode, aphids, scale insects, bark beetle, budworms, caterpillars, and weevils can cause problems. Pseudotsuga is also prone to dieback, butt rot, canker, needle cast, and brown felt blight.
