Adaptable, Hardy, Bonsai, Christmas Tree, Hedge Plant, Screen/Windbreak, Specimen Tree, Cold, Drought and Wind Tolerant
Colorado Blue Spruce is a medium to large, narrow, pyramidal conifer with horizontal branching to the ground. It typically grows 30 to 60 feet tall in cultivation, but may reach 100 feet or more where it grows naturally. It is native to the central Rocky Mountains from southern Montana and eastern Idaho south to New Mexico where it is typically found growing in moist locations from 6000 to 11,000 feet in elevation. Stiff, bristly, four-angled, green to blue-green to silver-blue needles (to 1 1/2 inches long) point outward from the branches in all directions. Cylindrical light brown cones, to 4 inches long, have flexible scales. Dark gray bark furrows on mature trees.
