The genus is predominantly native to the Old World with only one species of this genus originating from the Americas. Most are found in southern & eastern Africa, and Madagascar. They can also be found in south-eastern Asia and China. The most widely known of the Kalanchoe are the Mother of Millions species. This is a reference to several species that produce copious amounts of seedling along the leaf edge. These seedlings will drop off and root into any pots or soil below, hence the name. In large collections these plants can become quite invasive. In smaller collections these plants are much easier to control and make excellent starters for kids. In addition to the mother of Millions there are many other desirable species that would appeal to the collector. Some species can attain heights of 12’ or more making a very impressive specimen plant.
