Green Honey Myrtle, Green-flowered Myrtle

Melaleuca diosmifolia

The Story

Plant Bio

Melaleuca diosmifolia, commonly known as the green honey myrtle, is an erect, dense evergreen shrub endemic to the south-west of Western Australia. The species naturally inhabits shallow sandy soils, sandy clays, and granite outcrops, developing a bushy framework of crowded, narrow-oval leaves.

This species is distinguished by its unusual cylindrical, bottlebrush-like flower spikes of light green or greenish-yellow, which appear from spring through to summer. Unlike many other myrtles, the branches grow past the flowering head to form a leafy shoot.

Uses & Benefits:

Ornamental UsesUnusual light green, bottlebrush-like flower spikes and dense, crowded foliage.
Practical UsesExcellent for windbreaks, hedging, and screening in coastal exposures.
Ecological BenefitsAttracts native Australian birds, including honeyeaters and lorikeets, as well as native bees and other insects.

Planting

How to Grow

  1. Select a planting site in full sun to partial shade with highly drained, sandy or loamy soil.
  2. Dig a hole twice the width of the root ball and of equal depth, ensuring the soil is free-draining.
  3. Position the plant so the soil level matches the nursery pot, backfill, and water in thoroughly.
  4. Water regularly until established, then reduce watering to dry periods only.

Pro Tip

Prune lightly immediately after the summer flowering flush; cutting back severely into old, leafless wood results in poor, patchy regrowth.

Keep It Thriving

Care Guide

Do

  • Do plant in highly drained soils to prevent root decline.
  • Do tip-prune early in the plant's life to encourage a dense, bushy structure.
  • Do apply a low-phosphorus native fertiliser sparingly after flowering.

Don't

  • Don't allow the soil to become waterlogged or poorly drained.
  • Don't prune heavily into old, leafless wood.
  • Don't plant near sensitive bushland reserves in southern Victoria where it can become naturalised.
