History: The Colorado blue spruce is such a delight that nature seems to have kept it a well-guarded secret for a very long time. It was not until 1862 that this spectacular species was discovered growing in enchanted meadows and stream sides high up in the Rocky Mountains. Once found, the fame of this blue spruce spread quickly, and today it is one of our most widely planted landscape trees as well as the state tree of Colorado. When writing Handbook on Conifers in 1969, Henry Tuescher, curator emeritus of the Montreal Botanical Garden, called the Colorado blue spruce one of the five finest conifers. Tuescher gave no reasons for this honor except for the tree’s exceptional beauty.
