Blue Spruce, Picea Pungens
This is Colorado's state tree and is native to the Rocky Mountains, usually found along streamsides at higher elevations. It has sharp stiff needles that vary in many shades from bright green to silver blue. This tree does best in cooler climates and doesn't tolerate drought well as it needs regular watering. This is not the best conifer tree for our valley. It is an evergreen and has a conical, symmetrical shape and can grow up to 80 feet tall.
