Catharanthus roseus, commonly known as the Madagascar periwinkle or rosy periwinkle, is a species of Catharanthus native and endemic to Madagascar. Other English names occasionally used include Vinca, Cape periwinkle, rose periwinkle, rosy periwinkle, and “old-maid”. It was formerly classified in the Vinca genus as Vinca rosea. It is an evergreen subshrub or herbaceous plant growing 1 m tall. The species has long been cultivated for herbal medicine and as an ornamental plant. As an ornamental plant, it is appreciated for its hardiness in dry and nutritionally deficient conditions, popular in subtropical gardens where temperatures never fall below 5 °C to 7 °C, and as a warm-season bedding plant in temperate gardens. It is noted for its long flowering period, throughout the year in tropical conditions, and from spring to late autumn, in warm temperate climates. Full sun and well-drained soil are preferred. Numerous cultivars have been selected, for variation in flower colour (white, mauve, peach, scarlet and reddish-orange).
