Colorado Blue Spruce
The color of the blue spruce stands out no matter where you put it. A slow growing tree, the Colorado blue spruce is native to the Rocky Mountains. They need to be placed in a spot where it will have full sun conditions or the blue color will fade. They grow to be about 30-60 ft. tall and will spread to be about 10-20 ft. wide. They work well in a privacy screen mixed in with other evergreens.
