Blue Rug Juniper
Juniperus horizontalis ‘Wiltonii’ · a blue creeping juniper
A flat, silver-blue carpet that takes on a purple tinge in winter, spreading fast over hot, dry slopes, rock walls and coastal sites. It shrugs off drought, salt, wind and deer, and helps stop erosion on banks. Give it full sun and well-drained soil; in shade or constantly damp ground it fails.
