Big-cone Douglas-fir, Big-cone Spruce, Bigcone Douglas-fir
Pinaceae (Pine Family)
USDA Symbol: PSMA
Big-cone douglas-fir is a 40-60 ft., pyramidal evergreen with a 20-30 ft. width. The lower branches are elongated and with slender, often pendulous, branchlets. The flat needles are a very dark blue-green. Evergreen tree with open, broad, conical crown of long, spreading branches.
Bigcone Douglas-fir is native only in the mountains of southern California, mostly within national forests, and beyond the range of Douglas-fir. This species is distinguishable from its relative by its much larger cones (referred to in both common and scientific names) and by its sharp-pointed, bluish needles. The trees recover from fire damage and injuries by sprouting vigorously from trunks and branches.
