Pinaceae -- Pine family

    Gilbert H. Fechner

    Blue spruce (Picea pungens) is also called Colorado blue spruce,  Colorado spruce, silver spruce, and pino real. It is a slow-growing,  long-lived tree of medium size that, because of its symmetry and color, is  planted extensively as an ornamental. Because blue spruce is relatively  scarce and the wood is brittle and often full of knots, it is not an  important timber tree.
