Native to the western United States.
Medium-sized tree with a narrow pyramidal to nearly columnar habit.
Plants grow on poor, rocky soil in their native range. Best growth can be obtained when plant is located in full sun and in well-drained soils.
Most commonly used for its narrow habit and blue foliage as a specimen plant, hedge, screen or dwarf cultivars in mass.
Leaves opposite, typically scalelike and tightly appressed. Leaves may become needlelike on the inside of the plant or in shaded conditions. Leaves may be green in color, although typically they appear bluish due to the glaucous foliage.
No obvious buds.
Reddish brown in color. Young stems are slender and stiff but not distinctly four-sided.
Dioecious or monoecious, reproductive structures of no significant ornamental value.
Cones nearly spherical, about .33 inches. Dark blue to black with waxy bloom on female cones.
Seed, cuttings, or grafted for cultivars.
