Grey Honey-myrtle, Grey-leafed Honey Myrtle, Hoary Honey Myrtle

The Story

Plant Bio

Melaleuca incana, commonly known as the grey honey-myrtle, is an evergreen shrub endemic to the seasonally wet flats and swamps of south-western Western Australia. It develops a dense, fine-textured frame with gracefully weeping branches that reach up to three metres in height.

This species is distinguished by its small, linear leaves covered in fine, soft hairs that create a distinct hoary, blue-grey appearance. In cold winter weather, the pale green or silvery-green new growth transitions to pinkish or purplish tones before producing soft, white to pale yellow bottlebrush spikes.

Uses & Benefits:

Provides fine-textured, weeping blue-grey foliage and soft bottlebrush flowers that change colour with the seasons.

Functions well as a windbreak, hedge, or erosion control plant in seasonally wet or clay-heavy soils.

Supports nectar-eating native birds, native bees, and beneficial insects.

Planting

How to Grow

Select a planting site in full sun to partial shade with sand, loam, or clay soil.
Dig a hole twice the width of the root ball and of equal depth, ensuring reasonable drainage is available.
Position the plant, backfill with native soil, and water in thoroughly to settle the roots.
Apply a light mulch around the base, keeping it clear of the main stem to prevent rot.

Pro Tip

Ensure the plant is not allowed to dry out completely while establishing; once mature, it tolerates dry spells but retains a much denser canopy with occasional deep watering.
