The blue spruce (Picea pungens), also commonly known as Colorado spruce or Colorado blue spruce, is a species of spruce tree native to North America in Arizona, Colorado, Idaho, New Mexico, Utah and Wyoming.[4] It is noted for its blue-green colored needles, and has therefore been used as an ornamental tree in many places far beyond its native range.[5]
