Utah's First Official State Tree
Utah designated blue spruce (Picea pungens Engelm) as the official state tree in 1933 (replaced by quaking aspen in 2014). Blue spruce trees are found in the Wasatch and Uinta mountains of Utah at elevations between 6,000 to 11,000 feet (aspens are found in all 29 Utah counties). All State Trees
Blue spruce trees can be transplanted successfully and are widely used as ornamental trees. Generally silvery-blue in color, blue spruce has the ability to withstand temperature extremes. Blue spruce is also the state tree symbol of Colorado.
