Rocky Mountain Juniper (Juniperus scopulorum)

General: Rocky Mountain Junipers (Juniperus scopulorum) are coniferous (cone-bearing) trees with tiny, scale-like leaves. The cones are round berries about 1/4-inch in diameter. This species is most easily recognized by the tiny cones and the flat, drooping nature of the branchlets (more like a cedar than other local junipers).

In southern Nevada, Rocky Mountain Juniper is uncommon in the Spring, Sheep, and Virgin mountains in the Transition (Yellow Pine Forests) and Canadian (Pine-Fir Forest) life zones.

Family: Cypress (Cupressaceae).

Other Names:

Plant Form: Upright shrub to short tree.
