It's name is a little redundant, but very descriptive, as this evergreen grows a mere 6 inches tall and eventually about 3 to 4 feet across. Grey-green foliage retains color throughout winter. It is useful on slopes and when draped over walls. Have also seen this cultivar at nursery's propped up on stakes to create an upright, mounding, art-juniper thing.
Grow in any soil that is well draining, including sandy, gravelly, or clay soils, but they must be well draining. Best growth in full sun. Once established, it tolerates dry soils and heat. Avoid shearing, as that will made the juniper woody and stiff; instead, prune selectively if necessary (see Guides).
