Corky passionflower

Native to South America, corky passionflower is an aggressive perennial vine with many long tendrils.

In forests, it can out-compete ground cover species and climb and smother shrubs and small trees. Corky passionflower is recorded as a weed in a number of countries throughout the Pacific region.

Corky passionflower is not a prohibited or restricted invasive plant under the Biosecurity Act 2014.
