Colorado Blue Spruce
A magnificent sight of silver blue-green spruce and is rated one of the most popular evergreens. This species can withstand wind better than most spruces due to a wide-spreading and moderately deep root system. Full sun is ideal for this tree, meaning it should get at least six hours of direct, unfiltered sunlight each day. It grows well while young and matures at 50-75' tall and a 10-'20' spread in the landscape. Blue Spruce is commonly used as a windbreak, a noise barrier, and as a property line designator, especially when planted in rows. Not only does it provide food for wildlife, but it also provides a wide variety of animals with shelter. Colorado blue spruce trees attract nuthatches, siskins, squirrels, and chipmunks.
