Comments:
Douglas-fir, is a medium-sized to very large conifer that grows 50-80' tall in cultivation, but to 300+' tall in the wild. Leaves are flat, linear, spirally-arranged, encircling the branch completely, dark green needles (to 1.5" long) with white banding beneath. Needles are fragrant when bruised. Female cones to 4.5” long, pendulous, with unique three-pointed bracts, protruding above each scale, distinguishing this tree from all other conifers. The species is indigenous to coastal areas and up to 5500' in elevation in the mountains from British Columbia south to central California.
Best grown in medium to wet, well-drained soils in full sun. Does best in locations with abundant air and soil moisture. A good tree for northern and northwestern climates, but not for areas that have hot and humid summers with periods of drought.
