Blue Spruce

Also known as Colorado Blue Spruce, Colorado Spruce, Silver Spruce, Parry Spruce

Blue spruces dominate montane river valleys and moist mountain slopes across the central Rocky Mountains with their striking silver-blue foliage. Their sharp, four-angled needles grow radially on stiff branches, creating a dense conical silhouette that provides shelter for overwintering birds and small mammals. Mature trees produce pale brown, papery cones that release winged seeds into winter winds.
