Acacia baileyana

(Cootamundra Wattle)

This plant is an interesting one to have featured in our Weed Watch in that it is an Australian native plant. The Cootamundra wattle, Acacia baileyana, is indigenous to (found naturally in) Southern New South Wales. In this region it is not a problem, and in fact could make the featured native plant section on this site but for the effect it has on the natural vegetation in many other states.

The seeds of this small tree are spread by the spring-loaded action of its pods, and also by ants and birds. When it gets into the bush, the Cootamundra Wattle can replace local native shrubs and shade out native grasses and wildflowers.

Dedicated gardeners may be able to control the spread of this plant with good gardening practises. When it finishes flowering, prune off the old flower heads. This will prevent seeds forming, and also prolong the life of the tree.

But what will happen if you move house and the new owners of your garden aren’t so conscientious?
