About Blue Rug Juniper
Juniperus horizontalis 'Wiltonii' is a moderate-growing spreading groundcover in the Cupressaceae family. It reaches around 15 cm tall and 2.5 m wide at maturity, with evergreen and silver-grey foliage.
Where to grow Blue Rug Juniper
Blue Rug Juniper suits cool-temperate, warm-temperate and Mediterranean climates and grows best in full sun. It is frost hardy and shrugs off cold winters. It also tolerates salt-laden coastal winds and is a genuinely water-wise choice.
Soil & planting
Blue Rug Juniper does best in free-draining and sandy soil. Plant into well-prepared ground, firm the soil around the roots and water deeply to settle it in.
Watering & feeding
Blue Rug Juniper performs well with relatively little water once established. Feed as new growth begins, following the rate on a balanced garden fertiliser. Keep a newly planted specimen evenly watered through its first season; established plants can then follow the water needs above.
Pruning & care
Tip-prune Blue Rug Juniper in spring to maintain a dense, shapely habit. For most gardens, maintenance is low maintenance.
Using Blue Rug Juniper in the garden
Blue Rug Juniper earns its place for holding soil on banks and slopes and pots and courtyard containers. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
Blue Rug Juniper sits most comfortably beside plants adapted to happy on low water and cool-temperate climate. A small cluster gives stronger visual impact than isolated plants scattered through the garden.
Good to know
It is regarded as non-toxic and pet-safe.
