Creeping juniper 'Wiltonii'
FamilyCupressaceae
Juniperus horizontalis ‘Wiltonii’, often called ‘Blue Rug’ creeping juniper, is a highly prized groundcover conifer known for its brilliant silvery-blue foliage and exceptionally dense, prostrate habit. This variety is distinguished by its strictly horizontal growth, forming an even plant mat ideal for stabilizing embankments, covering large areas, adorning rockeries, and structuring sunny flowerbeds. Its evergreen foliage, finely textured and hugging the ground, maintains a strong bluish tint all year round, potentially taking on a slight purplish hue in winter. Very hardy, drought-tolerant once established, and undemanding regarding soil type, ‘Wiltonii’ is perfectly suited for northern gardens and sustainable landscaping. Its density, longevity, and minimal maintenance make it a reliable choice for challenging areas requiring a robust and decorative groundcover.
