What you need to know

Although wonga wonga vine is not a legally declared pest plant, it may still be invasive in some situations. Consider lower risk alternatives for your garden, such as native plants.

Disturbed forest, shrubland, coastal cliffs, rocky sites, gardens.

Seeds dispersed by wind. Vegetative spread from layering. Human-mediated dispersal through dumping of garden waste, deliberate plantings and movement of contaminated soil.

Can form dense infestations and prevent native seedling recruitment.

Site Management

Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
