Hoya carnosa (L.f.) R.Br., Asclepiadeae 16 1810. (syn: Asclepias carnosa L.f.; Cynanchum carnosum Decne.; Hoya chinensis (Lour.) Traill; Hoya intermedia A.C.Sm.; Schollia carnosa (L. f.) Schrank ex Steud.; Schollia chinensis (Lour.) J. Jacq.; Stapelia chinensis Lour.);
It is a common house plant grown for its attractive waxy foliage, and sweetly scented flowers.
The flowers are typically light pink, but may vary from near-white to dark pink; they are star-shaped, and are borne in clusters that look like tiny wax miniatures. The surface of the flowers are covered in tiny hairs giving a fuzzy sheen to them. They are heavily scented and may produce excess nectar that drips from the flowers. Like all Hoyas, this species flowers from specialized perennial structures referred to as spurs. These appear from the axils of the leaves and stem; flowers may not be produced when the spurs first appear, but in time buds emerge from the tips. Each season new flowers are produced on these same spurs, so they should not be damaged or removed.
H. carnosa has been in cultivation for more than 200 years and has given rise to many cultivars that vary in foliage form or flower color.
Recent studies at the University of Georgia have shown H. carnosa to be an excellent remover of pollutants in the indoor environment.
