Many of the junipers (Juniperus) make excellent ground covers in sites with full sun and well-drained soil. Creeping juniper (J. horizontalis) is one of the lowest growing at only 6-8 inches tall. Bar Harbor, Blue Rug, and Blue Chip are cultivars with blue-green foliage. All are hardy in Zones 3-9. Shore juniper (J. conferta) is hardy in Zones 6-10. At 1-2 feet tall, it makes a great ground cover, especially in coastal areas or locations subject to salt spray from streets and driveways. Japanese garden juniper (J. procumbens), Zones 4-9, makes a good 2-foot-tall ground cover, but it is susceptible to juniper blight, a fungal disease. Lower-growing forms of savin juniper (J. sabina) are also excellent ground covers. Arcadia and Broadmoor have bright green foliage; Skandia has blue-green needles.
