Gardeners who love plants with striking color may find themselves drawn to the cranberry hibiscus (Hibiscus acetosella). This African native produces deep red to burgundy, maplelike leaves that thrive in warm temperatures. Reddish-purple, trumpet shaped, 2-inch wide flowers appear in late fall and last through the winter. Known also as false roselle, red leaf hibiscus or maroon mallow, the cranberry hibiscus grows best in full sun and fertile, fast-draining soil. Hardy in U.S. Department of Agriculture plant hardiness zones 9 through 11, cranberry hibiscus grows quickly and requires spacing of 6 to 10 feet.
