Thyme honey myrtle

Melaleuca thymifolia. Family Myrtaceae. Shrub.

Also called Thyme-leaved honey myrtle, Thyme-leaf honey myrtle.

An evergreen shrub from eastern Australia, thyme honey myrtle has small aromatic leaves and pink-purple flowers with curled, feathery stamens. Gardeners grow it for its long flowering season, compact size and tolerance of moist soils; in colder climates it needs a container and frost-free winter shelter.

Care

Jobs through the year

WaterApr–May, Sep–Oct, every 14 days
Check established ground plants and water if dry; water new plants more often.
WaterJun–Aug, every 7 days
Deep-water established ground plants during prolonged dry weather; check pots more frequently.
FeedApr–May
Apply a light dose of low-phosphorus native-plant fertiliser only if growth is weak.
MulchMay
Mulch the root zone, keeping stems uncovered.
PruneApr–May
Remove winter-damaged shoots once new growth reveals what has survived.
PruneJul–Aug
Lightly trim after the main flowering flush, staying within leafy growth.
ProtectJan–Apr, Oct–Dec
Move pots into bright, ventilated, frost-free shelter; keep compost lightly moist over winter.
  • Water deeply through the first growing season, allowing the surface soil to begin drying between waterings.
  • Apply an organic mulch around the root zone, keeping it clear of the stems.
  • If growth is weak, apply a light dose of low-phosphorus native-plant fertiliser in spring.
  • Water container plants before the root ball dries out completely, and keep drainage holes clear.
  • Where winters are cold, move containers into a bright, frost-free place before the first frost.

Pruning. Lightly trim after the main flowering flush to encourage dense growth, and remove dead or damaged stems in spring. Avoid cutting hard into bare old wood.

Through the year

Spring
Plant after damaging frosts have passed, water thoroughly and mulch the root zone.
Spring
Check for winter damage and remove dead shoots once new growth shows.
Summer
Water young plants during dry weather and check containers frequently.
Late summer
Take semi-ripe cuttings from healthy, non-flowering shoots.
Autumn
Move container plants under bright, frost-free cover where outdoor winters are too cold.
Winter
Keep sheltered container plants lightly moist rather than wet, and provide good ventilation.

In the garden

  • Plant in an informal Australian native border with lomandra and flax lilies for contrasting leaf shapes.
  • Use several shrubs as a loose, low screen along a path or boundary.
  • Place beside a rain garden where soil is periodically wet but not permanently submerged.
  • Grow in a large patio container where the fine foliage and unusual flowers can be seen closely.

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

Plant it with: Lomandra, Flax lily, Dwarf bottlebrush and Swamp banksia.

Wildlife: Flowers attract bees and other nectar-feeding insects. Dense branching provides shelter for small garden animals.

Problems to watch for

  • Frost damage: young shoots may blacken after cold weather; shelter vulnerable plants and wait until spring growth begins before pruning damaged wood.
  • Sparse growth and few flowers: move container plants into stronger light and avoid heavy nitrogen feeding.
  • Root decline in containers: stagnant, airless compost can damage roots; use a freely draining mix and never leave the pot standing in water.
  • Scale insects: inspect stems and leaf undersides, remove small infestations by hand and use a labelled horticultural oil if needed.

Safety

This species is not well documented as poisonous to people, cats, dogs or horses, but species-specific safety information is limited. Do not treat its aromatic leaves or flowers as food, and do not give extracted oils to people or pets; concentrated oils can be harmful.

Easily confused with

  • Claw honey myrtle (Melaleuca pulchella)

    It also has claw-like pink-purple flowers, but its small leaves are arranged alternately along the stems rather than in opposite pairs.

  • Grey honey myrtle (Melaleuca incana)

    It has distinctly grey, hairy foliage, often drooping branches, and cream to pale yellow flowers rather than the usual purple flowers of thyme honey myrtle.

The name

The name thymifolia means thyme-leaved, referring to the small leaves that resemble those of thyme.

Propagation. Take semi-ripe cuttings in late summer and root them in a moist, airy propagation mix. Seed can also be surface-sown in spring; seedlings may differ from the parent, so use cuttings to preserve named forms.
