Colorado Blue Spruce Trees

Colorado Blue spruce, Pyramidal shaped evergreen with steel blue to blue-green needles.  Used as a lawn specimen because it grows in a perfect triangle shape for its whole life.  It will not get thin or loose lower branches if planted in full sun.  Makes a great screen.  They grow 30 to 60 feet at maturity, and prefer moist fertile soil.  They require no trimming but you can trim them when young if you want them to thicken.  Zones 2-7
