817 BR Spruce-Blue

The blue spruce (Picea pungens) is an evergreen tree native to North America, also called the Colorado spruce, known for its conical shape and silvery-blue needles. It is a medium-growth tree that can reach heights of 50 to 80 feet and is commonly used in landscaping and as a Christmas tree. The blue color comes from a waxy coating on the needles that can be rubbed off, and the tree requires full sun and well-drained soil.
