Blue Spruce

Blue Spruce TREEPicea pungens

Arizona Native

This tree is known for its stately, majestic, symmetrical form and its beautiful silver-blue color. A mature Blue Spruce can reach 100 feet in height. The largest measured tree is on the Ashley National Forest in Utah and is 127 feet tall and 15 feet, 10 inches in circumference.

This is a tree of the central and southern Rocky Mountains and is most abundant in Colorado. It is the state tree of Colorado and Utah, but in Arizona, it is replaced in frequency by the closely related Englemann spruce, which occupies the same mountainous niche.

Blue spruce is one of the most widely planted evergreens in the nation. Its attractive color, form, and tolerance to a variety of conditions make it a popular choice.
