The name Bigcone Douglas-fir (Pseudotsuga macrocarpa) comes from the large cones it produces. These cones are the largest among trees in this genus. It is also called the bigcone spruce and is found in mountainous areas in southern California. This evergreen conifer has a straight growth form with a conical crown. The roots are strong and spreading while the bark is thin and deeply ridged. The needle-like leaves are shed at five years. The long and spreading main branches have pendulous side shoots, as the seeds are large and heavy. It is mostly planted for habitable restoration as it is resistant to fires, insects, drought, and decay.
