Araujia sericifera (syn. Araujia hortorum Fourn., Physianthus albens C.Martius) is an ornamental plant in the Asclepiadoideae subfamily. Its common names include common moth vine, cruel vine, and white bladderflower.

This plant is native to South America. It is considered a noxious weed in many areas. It is a fast-growing, twining vine which can cover a tree canopy in two or three years, competing with the tree for light, water, and nutrients. It damages trees by this competition and by twining so tightly around their branches that it girdles them.
