Northwest Conifers

Blue Spruce  – Picea pungens


Needles: Sharp, thin, blue, stick out all around twig

Cones: 3" long with paper-thin scales

Bark: Gray-brown, breaks into scales on large trees


You can easily identify Blue Spruce by the distinctive blue needles. The blue color has, no doubt, made this tree one of the most popular ornamental trees. Although the color is variable from gray-green to blue, the onramentals are nearly always selected for the blue coloring. Like other spruces, the needles stand on small pegs.

Where it grows: Throughout the central and southern Rocky Mountains, above 5700 feet but not at the timberline. It is the state tree of Colorado and Utah.

Similar Trees: Engelmann Spruce is similar, but lacks the blue color of Blue Spruce. Although it is not common, Engelmann Spruce can hybridize with Blue Spruce.

Names: Pungens means "sharp" or "pointed" in Latin. Other names: Colorado Bue Spruce.
