Juniperus osteosperma (Utah Juniper) is a shrub or small tree reaching 3-6 m (rarely to 9 m) tall. It is native to the southwestern United States, in Utah, Nevada, Arizona, western New Mexico, western Colorado, Wyoming, southern Montana, southern Idaho, and eastern California.
It grows at moderate altitudes of 1,300-2,600 m, on dry soils, often together with Pinus monophylla.
The shoots are fairly thick compared to most junipers, 1.5-2 mm in diameter. The leaves are arranged in opposite decussate pairs or whorls of three; the adult leaves are scale-like, 1-2 mm long (to 5 mm on lead shoots), and 1-1.5 mm broad.
The juvenile leaves (on young seedlings only) are needle-like, 5-10 mm long. The cones are berry-like, 8-13 mm in diameter, blue-brown with a whitish waxy bloom, and contain a single seed (rarely two); they are mature in about 18 months.
