Juniperus horizontalis 'Wiltonii': Blue Rug Juniper – Classic Silver-Blue Ground Cover

Juniperus horizontalis 'Wiltonii' – Blue Rug Juniper, Wiltonii Creeping Juniper

Juniperus horizontalis 'Wiltonii', famously known as Blue Rug Juniper, is a classic, ultra-low, spreading conifer that forms a dense, undulating carpet of intense silver-blue, scale-like foliage. It hugs the ground at only 4–6 inches tall but can spread 6–8 feet wide. The foliage takes on purple tones in winter. It produces small, blue, berry-like cones. One of the most popular ground cover junipers for its color and durability.

Blue Rug Juniper demands full sun and excellent drainage. It thrives in poor, sandy, rocky soils and is extremely drought-tolerant once established. It is ideal for covering large banks, cascading over walls, or as a xeric ground cover. Avoid heavy clay and wet sites. It is deer-resistant and low-maintenance. A timeless, reliable evergreen for hot, dry, sunny slopes.
