As with all firs, there is one needle attached to the stem leaving a circular leaf scar. White fir is easy to identify from its foliage features. The needles go out and curve up creating a distinctive look that can be identified from afar. The needles are flat and have the same glaucous blue color on both sides. The specific epithet “concolor” meaning “with one color” refers to this feature. The needles reportedly have a citrus odor when bruised.
