Pot Size

A prostrate, cascading she-oak with fine, trailing, deep green stems that drape over edges, rocks and walls. Forms a dense, weed-suppressing mat in garden beds and spills beautifully from pots and retaining walls. Coastal, heat and drought tolerant, once established.

Best for: groundcover carpets, embankments, trailing over walls and “spiller” in pots.


Origin: Eastern Australia (NSW/Qld coastal)
Attracts: Habitat for lizards/beneficials; low nectar value

Plant Guide

What to use me for: Groundcover, erosion control on banks, pot/spiller, softening hard edges and steps.

I grow to: 0.15–0.3m high, spreading/trailling 1–2+ m.

Features: Dense, prostrate habit; handles salt, wind and reflected heat; excellent weed suppression once filled in.

Plant Care

Where to place me: Full sun to part sun. Best density in high light; OK in bright part shade.

How far to space me: For full cover: 0.6–1.0 m centres (closer for faster closure). On walls/pots: allow trail length.

Soil Conditions: Free-draining is essential; sandy/loamy ideal. Avoid waterlogging; mound and add large bark/perlite in heavy soils.

Extra-Care: Low water after establishment; trim edges to shape. Feed lightly in spring with slow-release fertiliser. Protection from SE QLD and Brisbane midday to afternoon sun to prevent scorching.
