Twiggy Emu-bush, Flowering Lignum, Lignum Fuchsia, Desert Lignum

The Story

Plant Bio

Eremophila polyclada, commonly known as the twiggy emu-bush, is a dense, strongly branching Australian shrub native to the arid inland floodplains and clay flats of the eastern states. It forms a massive, tangled thicket of stiff, widely spreading branches that weep at the extremities and bear narrow, deep green linear leaves.

Unlike many desert-dwelling emu-bushes, this species is highly adapted to heavy clay soils and tolerates periodic inundation around its root zone. During dry spells, the shrub sheds its foliage to conserve moisture, producing large, white to pale lilac tubular flowers with dark-spotted throats when water returns.

Uses & Benefits:

Produces large, tubular white to pale lilac flowers with dark-spotted throats over a long season, set against a sculptural, tangled branch structure.

Highly effective for windbreaks, dust control, and soil stabilisation on heavy clay soils and floodplains.

Provides critical nectar for honeyeaters and spinebills, supports native bees, and offers a safe, dense nesting habitat for small birds.

Planting

How to Grow

Plant in a sunny position with full sun to light shade, ideally in neutral to alkaline clay loam or heavy clay soil.
Water thoroughly during the establishment phase, then reduce watering to match natural rainfall patterns.
Prune lightly in autumn to maintain a dense, compact habit and prevent the branches from becoming too straggly.
Avoid applying high-phosphorus fertilisers; use a low-phosphorus native formulation sparingly if growth is slow.

Pro Tip

Do not panic if the shrub defoliates during extended dry spells; this is a natural drought-survival mechanism, and the plant will rapidly re-flush with foliage and flowers once watered.

Keep It Thriving

Care Guide

Do

Plant in heavy clay or duplex soils where other desert species fail.
Prune lightly after flowering to encourage a denser habit.
Allow the soil to dry out between watering intervals once established.

Don't

Do not prune severely into old, bare, woody stems as they may fail to shoot back.
Do not overwater during warm, humid weather to prevent root rot.
Do not apply standard high-phosphorus fertilisers.
