Summary of Invasiveness

Top of page

The following summary is from Witt and Luke (2017):

Description

Small evergreen tree or shrub [2–6 (–10) m tall] with no thorns/spines; young branchlets round or almost round in cross-section and covered with soft hairs.

Origin

Australia.

Reason For Introduction

Bee forage, shade and ornament.

Invades

Roadsides, disturbed areas, urban open spaces, forest edges/gaps, grasslands and watercourses.

Impacts

Can establish readily in a wide variety of climates, including dry areas, and tolerates mild frost. It grows rapidly and has the ability to form dense stands within a relatively short period, displacing native species and their associated organisms. By fixing nitrogen, it also alters soil nutrient cycling. In Australia, A. podalyriifolia can become naturalized wherever it has been planted.
