Araujia sericifera is a perennial ornamental plant in the genus Araujia belonging to Apocynaceae family. This plant was described in 1817 by the Portuguese botanist Félix Avelar Brotero. The synonym Araujia hortorum is in more frequent use in New Zealand. Its common names include moth plant, white bladderflower, common moth vine, cruel vine and false choko.
The genus name (Araujia) derives from António de Araújo e Azevedo, 1st Count of Barca (1754–1817), a Portuguese amateur botanist who conducted scientific studies and experiments in his own botanical garden. The Latin name sericifera of the species, meaning silk-bearing, refers to the silky hairs surrounding the seeds inside the fruits. Araujia sericofera is an incorrect taxonomic synonym for Araujia sericifera.
Araujia sericifera is a creeping vine that can climb up to 5–7 metres (16–23 ft) of height. If broken this plant releases a milky smelly exudate. Leaves are opposite, dark green, glossy and quite fleshy, almost triangular, with entire margins, about 10–12 centimetres (3.9–4.7 in) long.
The twining stems bear plenty of fragrant, chalice-shaped bisexual flowers, of about 2 centimetres (0.79 in) of diameter,with five white, creamish, violet or pale pink petals. The flowers are usually pollinated by moths (hence the common name of the plant), butterflies and bees (entomophily), but they are capable of automatic self-pollination. The structure of the flower includes a number of wedge-shaped openings which occasionally and inadvertently trap the pollinator's proboscis, leading to its death. The flowering period extends from July through September in the northern hemisphere and from November through February in the southern hemisphere. The pear-shaped fruits are large pods of about 8–10 centimetres (3.1–3.9 in) of length. They contain numerous black seeds attached to silky hairs which enable them to be dispersed by the wind.
The fast-growing vines can cover a tree canopy in two or three years, competing with the tree for light, water, and nutrients. They damage trees by this competition and by twining so tightly around their branches that it girdles them.
