Group of about 50 plants native to Cuba, Mexico, and Central America. Prized for colorful flowers produced nearly continuously in warm weather. The two species listed below are the most common; both look great billowing over the top of a retaining wall, massed on a slope, or used in raised planters and hanging baskets. Provide well-drained soil. Propagate by taking cuttings, layering branches that touch the ground, or divid- ing. Can be grown indoors in a sunny window. During active growth, water moderately and feed monthly with a general-purpose liquid houseplant fertilizer; then reduce water and fertilizer in winter.
