Douglas fir—Pseudotsuga menziesii
Family Pinaceae (Pine family)
Douglas fir is a coniferous evergreen tree.
In dry conditions, the needles tend to be closely spaced;
in moist soils trees are thin. They have dense, green to
very blue needles, and in native conditions, can grow 70
to 250 feet tall.
Optimum conditions for growth
Trees grow best in full sun and well-drained
soils. They require little water once established.
