Screw Pod Wattle
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.
- Common Name: Screw Pod Wattle
- Botanical name: Acacia implexa
- Legal Status: NEMBA Category 1a
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).
