Broad-leaved Paperbark, Five-nerved Paperbark, Paperbark, Punk Tree

Melaleuca quinquenervia

The Story

Plant Bio

Melaleuca quinquenervia, commonly known as the broad-leaved paperbark, is an erect evergreen tree native to the coastal wetlands of eastern Australia, New Guinea, and New Caledonia. The species is defined by its thick, multi-layered, papery white bark that peels in large sheets, and its stiff, lanceolate leaves featuring five distinct longitudinal veins.

This species produces creamy-white, bottlebrush-like flower spikes at the branch tips primarily during autumn and spring, attracting a wide range of native nectar-feeders. It exhibits exceptional tolerance to waterlogged soils and saline coastal winds, making it a critical habitat tree in floodplains and swamp margins.

Uses & Benefits:

Features highly tactile, multi-layered white papery bark and soft creamy-white flower spikes that contrast with the stiff, olive-green foliage.

Highly effective for erosion control along watercourses and stabilizing wet, poorly drained soils where other species fail.

Provides a critical food source for nectar-eating birds, native bees, and flying foxes, while serving as a key habitat tree in coastal wetland ecosystems.

Planting

How to Grow

Select a planting site in full sun to partial shade with ample space to accommodate the tree's mature canopy and root system.
Dig a hole twice as wide as the root ball and of equal depth, ensuring the soil is loosened to encourage outward root penetration.
Position the plant in the hole so the soil level matches the nursery pot, backfill with local soil, and firm down gently.
Water thoroughly immediately after planting, and maintain consistent moisture until the root system is fully established.

Pro Tip

Avoid planting this tree near underground pipes or paving, as the extensive, moisture-seeking root system will disrupt nearby infrastructure over time.

Keep It Thriving

Care Guide

Do

Mulch the root zone heavily to retain moisture and mimic natural swamp forest conditions.
Prune lightly after flowering to maintain shape and remove any dead or damaged wood.
Monitor young growth regularly for signs of myrtle rust, especially during warm, humid weather.

Don't

Do not plant this species close to domestic plumbing, sewer lines, or concrete pathways.
Do not prune heavily into old, leafless wood, as recovery and regrowth from bare branches is slow.
Do not apply heavy doses of high-phosphorus fertilisers, even though the species is not strictly phosphorus-sensitive.
