Dead Finish, Kurara

Acacia tetragonophylla

The Story

Plant Bio

Acacia tetragonophylla, commonly known as dead finish, is a resilient, much-branched shrub or small tree native to the arid and semi-arid regions of mainland Australia. It features rigid, four-angled phyllodes clustered in whorls that end in sharp, pungent points, providing a formidable barrier.

The species is highly distinguished by its exceptional drought tolerance and ability to survive prolonged dry spells by reducing physiological activity. In winter and spring, or following significant rainfall, it produces bright yellow globular flower heads on individual stalks.

Uses & Benefits:

Provides structural, architectural interest with its intricate, angular branching and bright yellow globular blooms.

Functions as an impenetrable security hedge or windbreak due to its dense, spine-tipped foliage.

Offers crucial protective nesting habitat for small native birds and supports local insect pollinators.

Planting

How to Grow

Select a planting site in full sun with excellent, rapid drainage, avoiding any low-lying areas prone to waterlogging.
Dig a hole twice as wide as the root ball but of the same depth, backfilling with the native soil without adding organic matter.
Water in lightly to settle the soil, then withhold regular watering, allowing the plant to rely on natural rainfall once established.

Pro Tip

Amateurs frequently fail with this arid acacia by treating it like a high-rainfall eastern Australian species; planting in heavy, poorly drained soil or over-watering will rapidly induce fatal root rot.

Don't

Do not over-water or allow the roots to sit in boggy, wet conditions.
