Araujia sericifera is a perennial vining plant in the genus Araujia, of the family Apocynaceae. The species was described in 1817 by the Portuguese botanist Félix Avelar Brotero. The synonym Araujia hortorum is in more frequent use in New Zealand.
Araujia sericifera is a creeping vine that can climb up to 5–7 metres (16–23 ft) high. When broken it 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 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. The plant is native to South America. It was introduced to Europe and other areas as an ornamental plant, but it is now considered a noxious weed.
