Juniperus horizontalis ‘Wiltonii’ Description

Juniperus horizontalis ‘Wiltonii’, commonly known as Blue Rug juniper, is a low, spreading evergreen conifer with fine silvery blue foliage. The trailing branches hug the ground and gradually form a dense mat, often developing attractive purple or bronze tints during cold winter weather. Mature plants generally remain around 10 to 20cm high but can spread 1.5 to 2 metres or more. Grow in full sun in almost any freely draining soil, including poor, sandy, gravelly or chalky ground. It is very hardy and useful on exposed banks, rockeries and low walls. Once established it tolerates drought well. Avoid persistently wet soil, particularly in winter. Pruning is rarely needed beyond shortening occasional young shoots that spread too far.
