Moth plant

Description

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. Its common names include moth plant, white bladderflower, common moth vine, cruel vine and false choko. Its attractive and abundant fragrant flowering make it a specimen worth cultivating. Its strong robustness combined with high seed production can make it invasive in certain environments, but not in France due to its sensitivity to frost. 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 species' Latin name sericifera means "silk-bearing" and 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 5–10 metres (16–33 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 and 1–6 centimetres (0.39–2.36 in) wide with an intact leaf margin. The upper side is dark green, bare and shiny, the underside is grey-green with felt-like hairs. When a stem, leaf or unripe fruit is broken, a white milky juice is produced at the breaking point. It is slightly toxic and can cause an allergic skin reaction when touched. The stems are thin and right-winding. They branch strongly and can lignify at the base. The plant usually wraps itself around other plants or around a post or the bars of a fence. The root system consists of a short taproot with superficial lateral roots.
