Habit: coniferous evergreen tree with a conical open form. The bluish-green to dark green leaves are needle like and 1 in (2.5 cm) long singularly arranged in two irregular rows. The bark is dark brown to black, and roughly fissured with large scales. Cones are characteristic having thin scales and three pronged bracts reaching beyond the scales. The female cones initially pink and formed at the ends of branches will eventually harden, turn brown and point downwards.
Ecology: found native to the interior montane regions of Western North America in either mixed conifer forests, pure stands or moist to dry open forests. In some areas of its range blue Douglas fir is seen at elevations as high as 10,700 feet (3262 m).
Growing Conditions: full sun in moist well-drained soil.
Pseudotsuga menziesii v. glauca is a variety of Douglas fir having blue-tinged leaves, growing much slower, smaller and more cold tolerant than the coastal Douglas fir, Psuedotsuga menziesii
