Summary ²

Douglas fir, with the scientific name Pseudotsuga menziesii, also known as Oregon pine or Douglas spruce, is an evergreen conifer species native to western North America. The common name is misleading since it is not a true fir, i.e., not a member of the genus Abies. For this reason the name is often written as Douglas-fir (a name also used for the genus Pseudotsuga as a whole).
