True to its name, the Colorado Blue Spruce is actually the state tree of Colorado having been found creeks and streams throughout the mountain areas.
Prized as an ornamental tree the actual needle colour of the blue spruce ranges from a powder blue to a dark green blue.
The young trees tend to be conical while the mature trees are more cylindrical with a taper top. These spruce are generally only grow 1-2 feet per year in open areas but will grow much faster in partial shade which is why they should always be planted in the north or east rows in a shelter belt.
