About

Pseudotsuga menziesii var. menziesii, commonly known as coast Douglas-fir, Pacific Douglas-fir, Oregon pine, or Douglas spruce, is a very tall evergreen conifer, being a variety of P. menziesii (Douglas-fir).

It is native to western North America and is used as timber.

How to grow it

Coast Douglas-fir is one of the world's best timber producers and yields more timber than any other tree in North America. The wood is used for dimensional lumber, timbers, pilings, and plywood. Creosote treated pilings and decking are used in marine structures. The wood is also made into railroad ties, mine timbers, house logs, posts and poles, flooring, pulp, and furniture. Coast Douglas-fir is used extensively in landscaping. It is planted as a specimen tree or in mass screenings. It is also a popular Christmas tree.

Where it grows

Coast Douglas-fir is native to western North America from west-central British Columbia, Canada, southward to Central California, United States. In Oregon and Washington, its range is continuous from the Cascades crest west to the Pacific coast, including the Pacific Coast Ranges. In California, it is found in the Klamath and California Coast Ranges as far south as the Santa Lucia Mountains, with a small stand as far south as the Purisima Hills, Santa Barbara County. In the Sierra Nevada, it ranges as far south as the Yosemite region. It occurs from near sea level along the coast to 1,800 m (5,900 ft) in the California Mountains. Further inland, coast Douglas-fir is replaced by Rocky Mountain or interior Douglas-fir (P. menziesii var. glauca). Interior Douglas-fir intergrades with coast Douglas-fir in the Cascades of northern Washington and southern British Columbia.
