Wetland indicator: FACU

The blue-green color of the needles is usually sufficient to distinguish this species from other native northeastern spruces, though it might be confused with planted specimens of Picea pungens (Colorado spruce) which has longer needles. The lack of hairs on the twigs and bud-scales is also diagnostic. Sometimes called cat spruce because the crushed or burned needles give off an odor similar to cat urine.
