Catharanthus roseus
Madagascar Periwinkle is a tender perennial grown as an annual in New Jersey. It has attractive, glossy leaves and rose-pink, phlox-like flowers, which bloom from June to frost. Cultivars offer additional color choices, including red, purple, and white. This plant thrives in summer heat, and is drought-tolerant once established. It grows best in well-drained soil. Minimize overhead watering to avoid root rot. Use Madagascar Periwinkle in beds and borders, as an edging plant, or as an annual groundcover. It can also be used in containers.
