Catharanthus roseus

Madagascar Periwinkle
Apocynaceae
Annuals, Evergreen, Perennials

Native to Madagascar. Good for summer-to-fall color in hot climates; thrives in dry or humid heat. Glossy green, 1- to 3-in.-long leaves cover bushy plant 1–2 ft. high and wide. Phlox-like, 1 1/2-in. flowers in pure white, white with rose or red eye, blush pink, or bright rose. Blooms all summer and keeps flowering after marigolds and zinnias have finished—until Thanksgiving if weather stays mild. Lives over in frost-free areas but may look ragged in winter. In desert regions, may also look poor in late summer. Provide good drainage and avoid overwatering.
