Cupressaceae
Juniperus horizontalis 'Wiltonii'
Blue Rug Juniper, Creeping Juniper, Wiltonii Juniper
Considered the lowest growing of all the ground-hugging junipers, 'Wiltonii' (often sold under the name 'Blue Rug'), is the standard by which all others of its kind are judged. Its trailing, woody stems form a spreading, evergreen carpet of feathery, bright blue-gray foliage which develops attractive purple tints in winter. Like all creeping junipers, it performs well in difficult areas, tolerating poor soil, dry conditions, and extremes of heat and cold. The parent species is native to most of temperate North America, including Alaska and Nova Scotia.
Creeping junipers are low-maintenance plants which grow best in full to part sun and are tolerant of a wide range of soils, as long as they are well-drained. This cultivar responds especially well to pruning to encourage denser foliage growth. Use it as a groundcover for erosion control on banks, slopes, or hot, dry spots. It is a terrific choice for rock gardens, and also looks beautiful when cascading over stone retaining walls.
