One-seed juniper is a rugged native evergreen tree or large shrub found in drier regions of the Southwest and southern Rocky Mountain foothills. It develops an irregular, often multi-trunked form with dense branching and blue-green foliage. Its natural shape gives it a strong, rustic character well suited to xeric landscapes and naturalized plantings. Because of its drought tolerance and adaptability, it is often used in restoration or low-water landscapes where a tough evergreen is needed.
