Common Name:

Screw Pod Wattle

Botanical name:

Acacia implexa

Legal Status:

NEMBA Category 1a

An erect or spreading tree 5-12m high, that often suckers (shoot rising from a woody plant, often some distance away from the main stem) freely, native to Australia. Pale yellow to cream fluffy ball-shaped flowers appear in summer. There are usually 4-8 flowers on each raceme. A highly distinguishing feature is the seed pods, which are curved to twisted or coiled, raised over seeds, 6-20cm long, 4-7mm wide, and firmly papery to leathery.

Additional Info

  • Where does this species come from?

     Indigenous to the East coast of Australia (coastlines of Queensland, New South Wales and Victoria).

    Why is it a problem?

    Acacia implexa is a long lived, fast growing tree that invades agricultural lands. It impacts indigenous species richness and abundance by competing with – and replacing – native vegetation. Dense stands along watercourses reduce stream flow.

    Means of reproduction?

    This species reproduces mainly through vegetative suckering, followed by seed dispersal via waterways and human activity (roadsides and clothes).
