It is an evergreen climbing invasive species plant, growing to 20–30 m high where suitable surfaces are available and also growing as a ground cover where there are no vertical surfaces. It climbs by means of aerial rootlets which cling to the substrate.
The leaves are alternate, 50–100 mm long, with a 15–20 mm petiole; they are of two types, with palmately five-lobed juvenile leaves on creeping and climbing stems, and unlobed cordate adult leaves on fertile flowering stems exposed to full sun, usually high in the crowns of trees or the top of rock faces. The flowers are produced from late summer until late autumn, individually small, in 3–5 cm diameter umbels, greenish-yellow, and very rich in nectar, an important late autumn food source for bees and other insects. The fruit is a purple-black to orange-yellow berries 6–8 mm diameter, ripening in late winter, and are an important food for many birds, though somewhat poisonous to humans. There are one to five seeds in each berry, which are dispersed by birds eating the berries.
