General description

Kudzu vine is a deciduous twining, semi-woody vine, 10-30 m long, growing from semi-woody tuberous roots. Dark green often lobed leaflets have pubescent undersides and grow in groups of three. Fragrant purple (1-1.5 cm) flowers are produced in groups of 30-80 on long branched stems (< 25 cm long). The fruits are hairy bean like pods.

It grows in agricultural areas, disturbed areas, exotic and indigenous forests, grasslands, riparian zones, scrub/shrublands, and urban areas.

Spread by birds and regenerates from root fragments transported by machinery, vehicles, water and garden waste dumping.

It forms dense monocultures through rapid growth and suppression of desirable species. It can be difficult to control due to fast growth and masses of underground tubers.

Site management

Recommended approaches

1. Report it immediately to the Auckland Council Biosecurity team, who will arrange for its control at their expense.
2. Dig out all tubers

Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
