Rocky Mountain Juniper (Juniperus scopulorum) is a rugged, evergreen conifer native to western North America. Valued for its attractive blue-green foliage, narrow pyramidal form, and outstanding drought tolerance, this hardy tree is widely planted for windbreaks, privacy screens, wildlife habitat, and ornamental landscapes. Its ability to thrive in rocky soils, dry climates, and harsh growing conditions makes it an excellent choice for both residential and conservation plantings.
As it matures, Rocky Mountain Juniper develops a dense canopy that provides year-round color and shelter for birds and wildlife. The tree produces small blue berry-like cones that are an important food source for many bird species. Its adaptability, longevity, and low maintenance requirements have made it one of the most popular native evergreen trees throughout the western United States.
