The Story

Plant Bio

Chamelaucium uncinatum, commonly known as Geraldton Wax, is an erect, open-branched evergreen shrub native to the coastal sands and hillsides of Western Australia. The species features slender, upright stems clad in narrow, pine-like leaves that release a strong aromatic scent when crushed.

The small, cup-shaped flowers feature five waxy petals surrounding a prominent central calyx cup, appearing in profuse sprays from late winter through to early summer. Flower colours range from white and pink to deep purple-red, often darkening in tone as the blooms age.

Planting

How to Grow

  1. Select a planting site in full sun to partial shade with exceptionally well-drained sandy or gravelly soil.
  2. Dig a hole twice the width of the root ball and plant at the same depth as the nursery container, avoiding collar burial.
  3. Water moderately during establishment, then reduce watering to rely on natural rainfall once the root system is established.
  4. Apply a low-phosphorus, slow-release native fertiliser sparingly in spring to support growth without shortening the plant's lifespan.

Pro Tip

Prune the flowered stems back by one-third to one-half immediately after flowering finishes in early summer; cutting into old, leafless wood prevents reshooting.

Keep It Thriving

Care Guide

Do

  • Prune hard annually immediately after flowering to maintain a dense, bushy habit.
  • Ensure the soil is exceptionally well-drained to prevent fatal root rot.
  • Plant in an open position with excellent air circulation to minimise fungal leaf diseases.

Don't

  • Do not prune heavily into old, brown, leafless wood as it will not reshoot.
  • Do not overwater or allow the soil to become waterlogged.
  • Do not apply standard high-phosphorus fertilisers.
