Shrubs Blue Rug Juniper

Introduction to Blue Rug Juniper

Blue Rug Juniper is a low-growing, spreading evergreen shrub prized for its dense, blue-gray foliage that adds cool-toned color and texture to any landscape. Growing only 4 to 6 inches tall but spreading up to 8 feet wide, this ground cover forms a wide, carpet-like mat that is perfect for covering large areas. This shrub’s fine, needle-like foliage remains attractive year-round, providing consistent visual interest. Though it produces small blue-green cones rather than showy flowers, the plant’s foliage is the main landscape feature.

Commonly used in rock gardens, erosion control on slopes, landscape beds, and borders, Blue Rug Juniper thrives best in full sun. It is especially effective for preventing soil erosion while adding aesthetic appeal with its unique blue-gray color and low profile.
