(Also known as Cat's Claw Creeper)
Dolichandra unguis-cati syn. Macfadyena unguis-cati
Type of weed: Climber, scrambler or groundcover
Perennial woody vine with stems extending for 20 m or more. Plants have tubers and adventitious roots (roots arising from the shoots). Distinctive 3 ‘claws’.
Leaves comprise two egg-shaped to elliptic leaflets.
Flowers are yellow with orange lines in the tube. It flowers in spring.
Fruit contains numerous seeds with membranous wings.
The membranous wings on Cat’s Claw seed aid dispersal, particularly by water and wind. Although seed viability is low, seed production is high. Established plants can reproduce vegetatively from tubers and creeping stems. Detached tubers and cuttings may re-sprout in moist and dry conditions.
Impact on bushland
If left untreated the plant can grow to have very thick stems. Cat’s Claw Creeper smothers trees and produces massive ground cover, outcompeting with native plants and reducing biodiversity.

Specific control tips for this weed
CONTROL MEASURE: IF THE WEED IS PART OF A NEW INFESTATION OF THE WEED ON THE LAND, NOTIFY THE LOCAL CONTROL AUTHORITY AS SOON AS PRACTICABLE
- Hand pull seedlings if you can remove all the roots and tubers.
- Scrape and paint/cut and paint with Glyphosate. Use a toothed instrument such as a saw; cut the aerial section approximately 500mm above the ground; scrape extensively above and below the cut and apply herbicide immediately.
- Drill and inject large stems.
- Spray with herbicide if there are no native plants nearby. A selective herbicide will ensure native grasses are not killed.
NB: Spraying vines is only effective in limited circumstances where the foliage is dense and not too high. Do not spray high, as the herbicide will be dispersed and miss the target.

State Priority Weed
- The plant must be eradicated from the land and be kept fully and continuously suppressed and destroyed; and the land must be kept free of the plant.
- If the weed is part of a new infestation of the weed on the land, notify the local control authority as soon as practicable.
