Abies magnifica var. shastensis, also known as Shasta Red Fir, is a large evergreen tree that grows well in heavy clay soils and requires a cool position in a good moist but not water-logged soil. It is very shade tolerant, especially when young, but growth is slower in dense shade. This tree prefers growing on a north-facing slope and is intolerant of atmospheric pollution. Shasta Red Fir is an ornamental plant. They produce prolific crops of seeds from about the age of 25 years. Shasta Red Fir is suitable as a Christmas tree product and is used for lumber and pulpwood. It is a high altitude tree, typically occurring at 1,400-2,700 m altitude, with a narrow conic crown. The bark on young trees is smooth, grey, and with resin blisters, becoming orange-red, rough and fissured on old trees. The leaves are needle-like, glaucous blue-green above and below, arranged spirally on the shoot. The cones are erect and disintegrate to release the winged seeds in fall. Shasta Red Fir is closely related to Noble Fir, but is distinguished by the leaves and shoot bark visibility.
