Wildlife value

Description Landscapers value White Fir for its concentric pyramidal shape and striking blue-cast foliage. Another commonly used name for this species is Concolor Fir.

As a native to the Rocky Mountains of the western United States, White Fir grows to an eventual height of more than 100'. In ornamental plantings it typically grows 75’, with a width of 20’-30’ in a symmetrical, conic and formal shape. It bears needles which are 2”-3” long, which are arranged horizontally on the stem. Needles curve up and out at their ends (like a human rib-cage). They are glaucous on both sides giving them a distinctive blue cast.

Young trees usually hold their branches to the base of the tree. Older trees however loose the lower one-third of their limbs.

Mature trees bear 5” long upright cones in the upper portion of the canopy. When mature the cones break apart releasing the pine nuts within.

White Fir tolerates a wide range of soil types, but prefers ones that are more acidic. In areas west of the Cascade Mountains they thrive on the humid winter conditions.
