From late summer to autumn, it produces masses of small, fragrant (cardamom-like), cream-coloured flowers on dependent racemes, which may be up to 30 cm (12 in) in length.

[3] Seedlings were found well away from habitation, roads and streams in Australia from 1988 onward, leading to the conclusion that the species produces seeds there.

It has been introduced to Africa, the Australasia–Pacific region, southern Europe, and North America; it is considered an invasive species in many tropical and sub-tropical localities.

[11] Despite its potential to be an invasive species in warmer areas of the mainland United States, it was still being sold there as a garden plant, in 2023.

[12] It is also sold as a garden plant in the United Kingdom,[13] although due to the climate it is possibly less likely to become an invasive species there.

Foliar spraying of glyphosate 360g/L at 1% concentration can manage prostrate growth and newly emerged vines.

[8] Cutting off vine stems near the ground is generally ineffective as a control measure; the severed upper portion can remain alive in a tree canopy, for up to two years—during which time it will continue to drop aerial tubers—and the plant readily re-establishes new vine stems from its subterranean tubers.

[9] Pulling down mature vines from trees is generally counter-productive, because the aerial tubers are readily detached and fall to the ground.

If it is necessary to do this for any reason, a tarpaulin or similar sheeting should be laid on the ground to capture falling aerial tubers.

It can spread at ground level, as a rhizome, and vine stems can form roots at any leaf node in contact with soil, which in turn can produce new subterranean tubers.

Stem cuttings and detached succulent leaves, even if just lying atop soil or moist leaf litter, can result in new plants.

"Scrape and paint" control can be used effectively, at any time of year, but foliar spraying is best done during the period of active growth.

In Australia, a species of beetle, Plectonycha correntina, native to South America, which feeds on the leaves of the vine, was introduced in 2011, as an attempted biological control.
