Molonglo Juniper-Leaf Grevillea

Grevillea juniperina 'Molonglo'

The Story

Plant Bio

Grevillea juniperina, the juniper-leaf grevillea, is an evergreen Australian shrub native to New South Wales and Queensland, characterized by needle-like foliage and spider-like flower clusters. The species grows in well-drained, acidic to neutral soils and relies on its dense, prickly habit to deter herbivores.

'Molonglo' is a low-spreading, wide-mounding cultivar selected in 1964 at the Australian National University for its prostrate groundcover habit. It produces apricot-gold flowers with prominent red styles from fall through spring, growing significantly wider than it does tall.

Uses & Benefits:

Ornamental UsesProvides dense, evergreen groundcover with unique apricot-gold flowers that bloom through the cooler months.
Practical UsesActs as an effective weed-suppressing barrier and deters foot traffic or pests due to its sharp, prickly foliage.
Ecological BenefitsAttracts hummingbirds, bees, and butterflies in North America, offering a valuable nectar source when other plants are dormant.

Planting

How to Grow

  1. Select a planting site in full sun with excellent drainage, such as a sloped bed or sandy loam soil.
  2. Dig a hole twice as wide as the root ball but no deeper, ensuring the crown sits slightly above the surrounding soil level.
  3. Backfill with native soil without adding organic amendments or phosphorus-heavy fertilizers.
  4. Water deeply to settle the soil, then apply a coarse, low-phosphorus mulch keeping it clear of the main stem.

Pro Tip

Prune lightly immediately after the main spring flowering flush to maintain a dense habit, taking care never to cut back into old, leafless wood which fails to regenerate.

Keep It Thriving

Care Guide

Do

  • Water weekly during the first summer until the root system is fully established.
  • Use only low-phosphorus or specialty native plant fertilizers if feeding is necessary.
  • Prune the green tips annually to encourage dense, compact growth.

Don't

  • Do not plant in low-lying areas where water pools or soils remain saturated.
  • Do not apply standard garden fertilizers, as high phosphorus levels are toxic to the roots.
  • Do not cut back into bare, woody branches because they will not produce new shoots.
