About

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.

Where it grows

J. occidentalis can be found in the Western United States—specifically southeast Washington, eastern and central Oregon, southwest Idaho, northeastern California and extreme northwest Nevada, north of 40° 30' N latitude, east of the Cascade Range.

Uses

Like other junipers, J. occidentalis produces a crop of cones called a juniper berry. While original European gins used berries from J. communis, several distilleries—particularly in Bend, Oregon—have used local western juniper to flavor their gin.
