A fast-spreading climbing vine capable of smothering native bushland has been found in Bilpin and Berambing, prompting a warning for Hawkesbury residents to watch for the plant on their properties.
In its Winter 2026 newsletter, the Western Sydney Weeds Authority said banana passionfruit, or Passiflora tarminiana, had recently been identified in the two mountain communities. Infestations along Bells Line of Road were treated before winter.
The Authority lists banana passionfruit as a local priority weed with a containment objective.
Originally introduced as a garden plant, banana passionfruit is known for its bright pink flowers and edible fruit. Despite its attractive appearance, the vine can climb into tree canopies, smother native vegetation and reduce habitat and food sources for wildlife.
The plant is native to South America and favours rich soils and cooler climates, making conditions around Bilpin and Berambing suitable for its growth.
Each fruit can contain up to 180 seeds, which can remain viable in the soil for at least 18 months. Birds, possums and foxes can spread the seeds after eating the fruit. Seeds can also be dispersed by water or through dumped garden waste.
Banana passionfruit has large, drooping pink flowers and distinctive three-lobed leaves with toothed edges and velvety undersides. It flowers and fruits into winter, producing long, banana-shaped fruit that changes from green to bright yellow as it ripens.
Mature plants develop woody stems and a dark-brown root system, and can climb high into surrounding trees.
Residents who suspect they have found banana passionfruit can contact the Western Sydney Weeds Authority on 02 4574 9600 or email inspections@wswa.nsw.gov.au.
