| Description |
Life zones and habitat: Foothills to subalpine (7500 to 11000 ft.); wide range of ecological conditions: low to high elevations, dry to wet conditions, warm to cold temperatures, and on nearly every soil condition; in Colorado, its natural range is in the mountains of the southern half of the state. Plant: Large, long-lived conifer tree; mature trees up to 125 ft. tall or 3 feet in diameter; branches arranged in whorls of 4 or 5, which are repeatedly branched in one plane to form flat, horizontal sprays; bark on young trunks is smooth, gray and blistered with resin vesicles, becoming thick, hard and deeply furrowed with scaly ridges with age; crown of young trees is symmetrical and sharp-pointed, becoming irregular and rounded with age. Needles: Single needle per fascicle, 0.6 to 2.4 inches long, and generally curved upward, grayish-green, not twisted. Cones: Slightly barrel-shaped cones 3 to 6 inches long, usually yellowish-green, maturing to brown or purple; upright on the branches; trees do not produce cones until about 40 years of age.
