Juniperus occidentalis, known as the western juniper, is a shrub or tree native to the Western United States, growing in mountains at altitudes of 800–3,000 meters (2,600–9,800 ft) and rarely down to 100 m (330 ft). It is listed as Least Concern on the IUCN Red List because it is a widespread species with an increasing population. [1]

Fruit berrylike, blue-black, with a bloom, soft, juicy, resinous, maturing in the second year, 2-3 seeds.
