Creeping Blue Rug Juniper
Juniperus horizontalis 'Blue Rug'Blue Rug Juniper is a popular evergreen groundcover known for its striking silver-blue foliage and tight, mat-forming growth habit. Staying very low to the ground, it spreads outward to create a dense, carpet-like layer that suppresses weeds and provides year-round color. The foliage retains its cool blue tone throughout the seasons, sometimes developing purplish hues in winter, adding subtle seasonal interest. Its rugged beauty makes it a standout choice for rock gardens, slopes, pathways, and areas where low maintenance is a priority.
Exceptionally cold-hardy and drought-tolerant, Blue Rug Juniper thrives in full sun and poor, well-drained soils. It is especially valued for erosion control on banks and hillsides, where its spreading branches help stabilize soil. Once established, this juniper requires very little care and performs reliably in a wide range of climates. Whether used as a groundcover, accent plant, or mass planting, Blue Rug Juniper offers long-lasting structure, color, and durability with minimal effort from the gardener.

Plant in full sun for best color and dense growth. Space plants to allow their spreading habit. Spring or fall planting is ideal.
Watering
