Araujia sericifera aka White Bladderflower

Araujia sericifera, also known as moth plant, white bladderflower, common moth vine, cruel vine, and false choko, is a perennial vining plant in the genus Araujia, of the family Apocynaceae. It was described in 1817 by the Portuguese botanist Félix de Avelar Brotero and is native to South America. The plant has attractive and abundant fragrant flowering, making it a specimen worth cultivating, but its strong robustness combined with high seed production can make it invasive in certain environments, such as California and South Africa. However, it is not invasive in France due to its sensitivity to frost. The plant is a creeping vine that can climb up to 5–7 metres (16–23 ft) high and has opposite, dark green, glossy, triangular leaves with entire margins, about 10–12 centimetres (3.9–4.7 in) long. When broken, it releases a milky, smelly exudate. 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. Araujia sericifera will germinate from seeds in 3 to 6 weeks and prefers moderate, moist soil. It can be grown as a tender annual or as a container plant in most zones. Over winter, keep this plant in a bright, cool location. Despite its invasive tendencies, it remains a popular ornamental plant and is also known as Araujia hortorum, which is in more frequent use in New Zealand.
