Leaves are needle like, arranged spirally on the stems, older stems with the leaves forming 2 rows but not like most firs. Leaves leaning forward on most stems. Each leaf is about 1" long and has a very sharp point. Leaves are 4-sided like all spruce trees but these are put in the "flat" group. They can not easily be rolled between your fingers. Upper surface is medium to dark green while the lower surface has 2 distinct white bands. Its these white bands that give the tree a bluish cast.
Young stems are orangish red colored and like all spruce trees they are rough to the touch due to the small projections (pulvinus) at the base.
Cones are variable in size ranging from 1-1/2 to 3-1/2" long. Light brown or tan when mature, purplish when ripening in the tree. Scales are papery, somewhat undulated and notched at the tip. (Resemble Colorado blue spruce and Engleman spruce cones.)
Trunks can be huge with a buttressed base, but in cultivation I don't think you are likely to see that. Rough like all spruce trees, broken up into smaller plates, gray brown in color.
Misidentification
Colorado blue spruce as the cones and the potential bluish foliage can be similar. The Colorado spruce has longer leaves, much sharper and are generally held perpendicular to the stem.
