Juniperus horizontalis 'Wiltonii', commonly known as Blue Rug Juniper, is a hardy, low-growing evergreen ground cover celebrated for its silvery-blue foliage that maintains its color year-round. Perfect for erosion control or cascading over slopes, its dense spreading nature provides excellent weed suppression and visual appeal. This adaptable cultivar thrives in various climates and soils, making it ideal for rock gardens, borders, or as a landscape accent. It is one of the most popular choices for creating a carpet-like effect.
