Utah State Tree: Blue Spruce

(Pinaceae Picea pungens)

Adopted on February 20, 1933.

The blue spruce, (Pinaceae Picea pungens,) was chosen by the Utah State Legislature in 1933 to be the Tree.

The tree is found in the Wasatch and Uinta mountains at elevations between 6,000 to 11,000 feet. It can be transplanted successfully and is widely used as an ornamental tree. Its foliage is generally silvery blue in color and has the ability to withstand temperature extremes.

The quaking aspen replaced the Colorado blue spruce, which had held the honor of state tree since 1933 on February 20, 1933

Utah State Tree: Blue Spruce

The four-angled needles of the blue spruce are from 3/4 to 1 1/8 inches long and are dull blue green. This large tree has gray or brown bark that is furrowed into scaly ridges. Cones are from 2 1/2 to 4 inches long and are light brown with long, thin, irregularly toothed scales.

It is a slow-growing, long-lived tree of medium size that, because of its symmetry and color, is planted extensively as an ornamental. Because blue spruce is relatively scarce and the wood is brittle and often full of knots, it is not an important timber tree.
