Cone of a Douglas fir (Pseudotsuga menziesii)—Grant Heilman Photography

Any of about six species of coniferous evergreen timber trees (see conifer) that make up the genus Pseudotsuga, in the pine family, native to western North America and eastern Asia. Long, flat, spirally arranged yellow- or blue-green needles grow directly from the branch. The North American tree commonly called Douglas fir is P. menziesii (sometimes P. douglasii). Douglas firs may grow to 250 ft (75 m) tall and 8 ft (2.4 m) in diameter. One of the best timber trees in North America, it is also a popular ornamental and Christmas tree and is used for reforestation along the Pacific Coast.
