Showy honey myrtle

Sun

Full sun; tolerates light shade but flowers less freely.

Water

Water regularly during establishment, then deeply during prolonged dry spells. Avoid persistently wet soil.

Soil

Well-drained sandy, gravelly or loamy soil; tolerates coastal soils and some alkalinity. Improve drainage on heavy clay.

Height

10-20 ft (3-6 m)

Spread

10-20 ft (3-6 m)

Flowers

Rounded mauve-pink to purple flower heads, fading paler with age, mainly from late spring through summer; scattered flowers may continue into autumn in mild climates.

Foliage

Evergreen. Small, leathery, oval to oblong green leaves on densely branching stems; older trunks develop pale, peeling, papery bark.

Growth

Moderate to fast in warm conditions.

Care needed

Spreads vigorously: plan to contain it.

Growth rate

Fast

• Plant in spring after frost risk has passed, allowing room for the mature spread.
• Water deeply through the first growing season, letting the soil surface dry between waterings.
• Apply a 2-3 in (5-8 cm) layer of mulch, keeping it clear of the trunk.
• Feed only if growth is poor, using a light application of low-phosphorus fertiliser in spring.
• Choose a sheltered, freely drained position at the colder edge of its range; protect young plants from frost.

Pruning. Lightly trim after the main flowering flush to keep growth dense, and remove dead or crossing branches as needed. Begin shaping young plants early if you want a hedge or a small tree with an exposed trunk.

Spring

Plant after frost risk has passed and water thoroughly.

Spring

Refresh mulch and check that it does not touch the trunk.

Summer

Water establishing plants deeply during dry weather; established plants usually need much less.

After flowering

Lightly trim long shoots if a compact outline is needed.

Autumn

Check nearby bare ground for unwanted seedlings, especially in Australian coastal gardens.

Winter

Protect young plants during forecast frosts and check that winter rain drains away freely.

• Use as an informal coastal screen or wind-filtering hedge, allowing space for its broad habit.
• Train as a small multi-stemmed tree to show the papery bark above low planting.
• Combine with coastal rosemary and lomandra in a dry, Australian-native border.
• Use as a flowering background shrub in a sunny wildlife garden.

Garden styles it suits: Australian native, Coastal, Mediterranean, Wildlife garden, Pollinator garden and Low-maintenance.

Plant it with: Coastal rosemary, Lomandra, Kangaroo paw, Coastal banksia and Blue flax-lily.

Wildlife: Nectar-rich flowers attract bees and other insects, as well as nectar-feeding birds in Australia. Dense branches can provide shelter for small birds.

• Root rot in waterlogged soil: improve drainage before planting and avoid frequent watering once established.
• Frost damage to young growth: choose a warm, sheltered site and cover young plants during brief frosts; prune damaged shoots after new growth begins.
• Scale insects and associated sooty mould: check stems and leaf undersides, manage ants, and treat accessible infestations with horticultural oil according to the label.
• Sparse flowering or an open habit in shade: provide more sun and lightly trim after flowering rather than repeatedly clipping off developing flowers.

Not known to be toxic to people, cats, dogs or horses, although species-specific safety information is limited. It is an ornamental plant, not a food plant; discourage pets and children from eating the leaves, bark or woody seed capsules.

Where it spreads. Can self-seed and become an environmental weed in parts of southern Australia, including coastal south-western Western Australia outside its native range and parts of Victoria. Check local weed guidance before planting near bushland or coastal reserves.

• Thyme honey myrtle (Melaleuca thymifolia)

  Usually a much smaller shrub with tiny, narrow leaves and loose, claw-like mauve flower clusters rather than dense rounded heads.

• Swamp paperbark (Melaleuca ericifolia)

  Has narrow, almost needle-like leaves and creamy-white cylindrical flower spikes, rather than broad little leaves and mauve-pink rounded heads.

Melaleuca comes from Greek words meaning 'black' and 'white', referring to contrasting bark seen in the genus, while nesophila means 'island-loving', referring to its island habitat.

Propagation. Sow the fine seed on the surface of a moist, freely draining seed mix in warm conditions; do not bury it deeply. Semi-ripe cuttings taken in summer can also be used.
