Pseudotsuga menziesii (Douglas Fir)
Douglas Fir, Blue Douglas Fir, Green Douglas Fir, Oregon Pine
Tall and airy, Pseudotsuga menziesii (Douglas Fir) is a magnificent evergreen tree of pyramidal habit with drooping lower branches and ascending upper branches in youth. With age, the tree becomes irregularly conical as it drops its lower limbs. The flat, spirally-arranged, deep green or blue-green needles, 1.5 in. long (4 cm), are adorned with two white bands on their undersides. They are fragrant when bruised. Douglas Fir produces an abundance of pendant, ovoid, brown cones, 4 in. long (10 cm), with unique, conspicuous forked bracts extending beyond the cone scales. Ever-present, they hang from the tree like Christmas ornaments. The bark is brown-gray and smooth in youth, becoming reddish-brown, thick, and deeply furrowed with age. Native to western North America, Douglas Fir grows at a slow rate, about 12 in. per year (30 cm). It is prized as an important timber tree in Western North America and is one of the most commonly marketed Christmas tree species in the United States. Douglas Fir is excellent as a specimen, in groupings, or as a screen.
