- Description
-
Creeping Juniper is a native low-growing shrub that grows up to 1.5 feet high and branches can spread to form a dense mat up to 10 feet wide. It is found growing in rocky or sandy soils from rocky outcrops to streams. It is drought and deer tolerant and moderately salt tolerant. Creeping Juniper is fairly adaptable to soil types and pH as long as the soil is well-drained. Although this plant is native to North America, it is mostly relegated to the Northern United States more sporadically in rocky areas.
There are many cultivars available for use as a ground cover in hot dry areas as slopes, rock gardens or retaining walls.
