"The Juniper Blue Rug, 'Juniperus horizontalis Wiltonii', is an excellent ground cover or bank planting with it low growing thick foliage. The Blue Rug is so named because of its silver-blue color and low growing habit. Blue Rug will do well in almost any well drained soil and needs moderate moisture. This is the lowest growing of all Juniper plants and they will even cascade over walls. Prune young shoots to encourage branching, but older branches may not produce new growth."
