Pandorea pandorana is a fast-growing highly variable species of a woody climbing vine, it is found across continental Australia, Indonesia, Papua New Guinea, the Solomon Islands, New Caledonia and Vanuatu. In New Zealand, the species has become naturalised within disturbed native vegetation growing on larger trees in forested habitats.
It has glossy green leaves arranged oppositely along the stem. The pinnate leaves are around 8–16 cm long and have 3–9 leaflets of varying widths. The juvenile leaves are finer and have serrated margins and more finely divided into 7–13 leaflets.
Flowering occurs in spring. The tubular or funnel-shaped flowers are highly variable in colour, ranging from cream-white or all-white to maroon-throated, burgundy or even yellow-orange. Flowering is followed in summer by 3–8 cm long and 1–2 cm wide oblong-shaped seed pods, which are initially bright green before turning brown and releasing numerous papery seeds around 1-1.5 cm (0.5 in) in diameter which is released in large quantities.
