Juniperus horizontalis ‘Wiltonii’ – Blue Rug Juniper
Blue Rug Juniper is a hardy, low-growing evergreen prized for its cascading, silvery-blue foliage that adds year-round color to the landscape. This fast-spreading groundcover forms a dense, weed-suppressing mat, making it ideal for slopes, rock gardens, and erosion control.
Tolerant of poor soils, drought, and salt spray, this juniper thrives in full sun and requires minimal maintenance. Its evergreen foliage turns slightly purplish in winter, adding seasonal interest. Deer-resistant and pest-free, it’s a reliable choice for both residential and commercial landscapes.
