The genus Kalanchoe includes more than 100 plants, but only a few are regularly seen in cultivation. Kalanchoes are native to arid areas, and they are popular succulents. Modern hybrids are valued for their interesting leaf-forms or for their flowers. Flowering Kalanchoes are available in red, pink, yellow, or white. Like many succulents, these are not difficult plants to grow, providing you are careful with the water, especially in the winter.
