Colorado blue spruce is a medium to large pyramidal evergreen conifer native to the southern Rocky Mountains. The foliage has a bluish cast, ranging from bluish green to intense silver-blue. Their stiff needles are prickly when grasped and are pungently aromatic when crushed.
Colorado blue spruce prefers full sun and well-drained soil. Very content in cool, moist and fertile soils, it's proven quite adaptable. It can withstand many stresses, including drought, pollution, salt and wind. Use it as a specimen or screen.
