Kalanchoe (also written Kalanchöe or Kalanchoë), is a genus of about 125 species of tropical, succulent flowering plants in the Family Crassulaceae, mainly native to the Old World but with a few species now growing wild in the New World following introduction of the species. Most are shrubs or perennial herbaceous plants, but a few are annual or biennial. The largest, Kalanchoe beharensis from Madagascar, can reach 6 m tall, but most species are less than 1 m tall.
Members of the Kalanchoe genus are characterised by opening their flowers by growing new cells on the inner surface of the petals to force them outwards, and on the outside of the petals to close them. The genus was first described by the botanist Michel Adanson in 1763. Reportedly, the name came "from the Chinese name for one of the species." This Chinese species is thought to have been either Kalanchoe ceratophylla or Kalanchoe spathulata. Kalanchoe ceratophylla is called 伽蓝菜 in China, not very close in pronunciation: qiélán cài or jia lan cai depending on the romanisation.
The genus Bryophyllum was described by Salisbury in 1806 and the genus Kitchingia was created by Baker in 1881. Kitchingia is now regarded as a synonym for Kalanchoe, whereas some botanists treat Bryophyllum as a separate genus. Here are some fine specimens of various Kalanchoe hybrids, sold as indoor house plants here in Melbourne.
