Grevillea 'Honey Gem'

The Story

Plant Bio

Grevillea is a diverse genus of evergreen Australian shrubs and trees in the Proteaceae family, highly adapted to nutrient-poor soils. They are characterised by their unique, petal-less flowers where prominent, colourful styles form dense, nectar-rich inflorescences that attract native wildlife.

'Honey Gem' is a vigorous, upright hybrid cultivar selected in Queensland, distinguished by its deeply divided, fern-like foliage with silvery-hairy undersides. It produces large, cylindrical, golden-orange racemes that drip with nectar, blooming heavily from winter through spring.

Uses & Benefits:

Ornamental UsesFeatures deeply divided, fern-like foliage with silvery undersides and large, golden-orange cylindrical flower spikes.
Practical UsesServes as an effective, fast-growing privacy screen or windbreak in coastal and subtropical landscapes.

Planting

How to Grow

  1. Select a site in full sun with highly permeable, well-draining sandy loam or loam.
  2. Dig a planting hole twice as wide as the root ball and construct a raised mound if planting in heavier soil.
  3. Gently backfill without burying the root crown, and water in thoroughly to settle the soil.
  4. Apply a coarse organic mulch around the root zone, keeping it at least 10 centimetres clear of the main stem.

Pro Tip

Plant on a raised mound to ensure rapid drainage away from the collar, and avoid any fertilisers containing phosphorus, which quickly poisons the specialised proteoid roots.

Keep It Thriving

Care Guide

Do

  • Prune hard after the main spring flowering flush to maintain a dense, compact habit.
  • Use only low-phosphorus fertilisers formulated specifically for Australian native plants.
  • Ensure the soil drains rapidly to prevent waterlogging around the root system.

Don't

  • Do not apply standard, high-phosphorus garden fertilisers.
  • Do not allow mulch to pile up directly against the trunk of the plant.
  • Do not plant in low-lying areas where water pools after rain.
