A genus of perennial herbaceous plants, mainly endemic to Madagascar, with one species widely naturalised around the world and another from India and Sri Lanka. There are 8 described species and they are commonly referred to as Madagascar periwinkles, or just periwinkles, which is a label shared with the very similar looking genus Vinca. Members of Catharanthus have been cultivated as ornamental specimens and multiple cultivars have been produced in a wide range of flower colours, mostly from C. roseus (formerly known as Vinca rosea).
Root softwood cuttings in late spring, and semi-ripe cuttings in summer.
