The Blue Spruce is a medium-size evergreen growing 82 – 98 feet (25 - 30 meters) with a trunk diameter of up to 5 feet (1.5 meters), native to western North America. Its bark is thin and scaly, with a crown that matures from a conic shape in younger trees to a more cylindrical shape in older trees. The needles are small, growing to 0.6 – 1.2 inches (1.5 – 3 centimeters) long, with a dull gray-green to bright blue color. Within a mature tree, the reddish to violet cones will mature to a pale brown pendulous, slender cylindrical cone and will grow to be 2.3 – 4.3 inches (6 – 11 centimeters) long with flexible scales that are 0.78 – 0.94 inches (2 – 2.4 centimeters) long.
Due to their symmetrical shape and vibrant colors, the Blue Spruce has become one of the most popular garden conifers. They are not as popular as the Firs for use as a Christmas Tree due to their sharp needles, but are still very much liked due to their beautiful colors. The National Christmas Tree in Washington, D.C. is in fact a Blue Spruce, and the Blue Spruce is the State Tree of Colorado.
