About Rocky Mountain juniper
Juniperus scopulorum, commonly known as the Rocky Mountain Juniper, is an evergreen conifer with a columnar or pyramidal habit that can reach significant heights, offering an elegant and distinctive silhouette. Its scale-like leaves are blue-green to silvery, often producing small bluish cones resembling berries. It's an excellent choice for xeriscape gardens, as a windbreak, or as a specimen plant in large landscapes, providing year-round structure and color.
Native range

Care tips
This juniper thrives in full sun and well-drained soils, preferring dry conditions once established. It tolerates a wide range of soil types, including poor ones, but good drainage is crucial to prevent root rot. Watering should be moderate, allowing the soil to dry out completely between waterings, especially in arid climates. Avoid overwatering, which is the most common and detrimental mistake for this drought-tolerant species.
