Deciduous, climbing, vine up to 6 m tall. Stems, long, woody, round and weakly ribbed. Leaves opposite, and compound (bi-pinnate), falling in autumn. Leaflets thick, sparsely hairy, entire (rarely 2-lobed). Flowers 2-3 cm diam, white, in large bunches, Jan-Mar. Seeds hairy, 5-6 mm long; with distinctive white-plumes, 3-4 cm long, in dense, fluffy clusters, May.
Wind or water-borne seed. Also via dumped vegetation and stem layering. Common in gardens.
Smothers and kills all plants to mid-canopy, prevents recruitment. Moves readily into shrubland and forest margins by layering.
Do not leave cut stems to mulch. Dispose by burning, soak in herbicide or deep bury. Replant bared areas promptly to minimise seedling regrowth. Check for seedlings at least 6-monthly.
1. Slash thick stems at 1 m and ground level (to prevent stump resprouting and aerial roots attaching from hanging stems). Stump paint with herbicide (1 g metsulfuron/L or 100ml Tordon BK/L, or 100ml triclopyr/L, or 200ml 2,4-D plus dicamba/L). Leave stems in air to die. Dispose of cut-away segments. All year round.
2. Use vial treatment - good for ground infestations. Pull up all stems possible and dispose. Treat remainder (1g metsulfuron/20 ml, 5-10 m apart). All year round.
3. Spray spring - autumn (125ml clopyralid/10L (Do not use clopyralid in home gardens) or 40ml triclopyr/10L).
Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
