Andorra Juniper

Juniperus horizontalis 'Plumosa'

The Story

Plant Bio

Juniperus horizontalis, or creeping juniper, is a prostrate, evergreen conifer native to North America, valued for its low-growing, spreading habit and extreme tolerance of difficult growing conditions.

'Plumosa', the Andorra Juniper, is noted for its feathery, soft-textured foliage and a slightly mounding, spreading form. Its gray-green summer foliage transforms to a distinctive purplish-bronze color in winter.

Uses & Benefits:

Ornamental UsesProvides excellent year-round texture and color, with gray-green summer foliage and an attractive plum-purple winter hue. Its low, spreading form is perfect for softening hardscapes and covering large areas.
Practical UsesIt is an extremely tough and durable groundcover, ideal for erosion control on sunny banks and slopes. Its drought and salt tolerance make it suitable for difficult sites like roadsides and coastal areas.
Ecological BenefitsThe dense branches offer shelter and cover for ground-dwelling birds and other small wildlife. The small, berry-like cones may be eaten by birds like cedar waxwings.

Planting

How to Grow

  1. Select a site that receives at least 6 hours of direct sun daily.
  2. Ensure the soil is well-drained; amend if necessary.
  3. Dig a hole as deep as the root ball and twice as wide.
  4. Gently tease apart the roots before placing in the hole.
  5. Position the plant so the top of the root ball is level with the soil.
  6. Backfill, water thoroughly, and mulch to prevent weeds.

Pro Tip

Ensure perfect drainage; junipers abhor wet feet and will quickly succumb to root rot in soggy soil.

Keep It Thriving

Care Guide

Do

  • Provide full sun for the densest growth and best color.
  • Water regularly during the first year, then only during extended drought.
  • Allow good air circulation between plants to prevent fungal diseases.
  • Use as a groundcover on slopes to help control soil erosion.

Don't

  • Do not plant in shade or poorly drained locations.
  • Avoid overhead watering, which can encourage fungal blights.
  • Don't bury the crown of the plant when planting or mulching.
  • Avoid heavy fertilization; junipers thrive in lean soils.
