The Story

Plant Bio

Leptospermum laevigatum, recently reclassified by taxonomists as Gaudium laevigatum, is a woody coastal shrub or small gnarled tree native to southeastern Australia. It develops a sculptural form with twisted trunks clad in flaky, papery grey-brown bark and carries small, rigid, grey-green leaves.

The species is highly adapted to extreme maritime exposure, tolerating severe salt spray and strong winds on coastal dunes. In late winter and spring, solitary or paired white flowers with numerous central stamens open along the stems.

Uses & Benefits:

Distinctive gnarled, twisted trunks and flaky bark provide year-round sculptural interest, complemented by a dense canopy of grey-green foliage.

Acts as an exceptional windbreak and soil binder, tolerating severe coastal winds, salt spray, and sandy soils.

Provides abundant nectar and pollen that attract native bees, butterflies, beneficial insects, and small nectar-eating birds.

Planting

How to Grow

Select a planting site in full sun or partial shade with highly permeable, well-drained soil.
Dig a hole twice the width of the root ball but of equal depth to prevent the stem from settling below ground level.
Position the plant, backfill with native soil without adding organic matter, and firm down gently.
Water thoroughly upon planting and maintain light watering until established, after which the plant relies on natural rainfall.

Pro Tip

Avoid planting in heavy, poorly drained clay soils, as subsurface waterlogging triggers rapid root rot and sudden plant collapse.

Keep It Thriving

Care Guide

Do

Prune lightly after spring flowering to maintain a compact shape if a formal hedge is desired.
Ensure the planting site has excellent subsurface drainage to prevent waterlogging.
Apply a slow-release native or low-phosphorus fertiliser in spring if soil is exceptionally poor.

Don't

Do not plant this species near sensitive native bushland outside its native southeastern Australian range due to its invasive colonising habit.
Do not overwater or allow water to pool around the root zone.
Do not prune heavily into old, bare wood unless attempting a deliberate hard coppice.
