Another entry from Claire today. She writes:
Kalanchoe fedtschenkoi belongs to a family of succulent herbaceous species and soft-stemmed shrubs, the Crassulaceae. Crassulaceae has about 34 genera and 1370 species spread over a wide range of the world (frequently in drier regions). This family is known for CAM photosynthesis, which they and many other groups of taxa utilize. CAM is an acronym for Crassulacean Acid Metabolism, an adaptive strategy to allow maximum water storage.
This beautiful species is a native of Madagascar, but is widely cultivated as an ornamental and houseplant. As it is a succulent, it requires little water and is very low maintenance. Kalanchoe fedtschenkoi easily establishes and can take root from even one leaf being transplanted (it has escaped cultivation and become invasive in some subtropical places).
The common name is lavender scallop, due to the slightly purplish/pinkish tinge of the leaves. Some pictures of the vegetative parts can be found on the University of Connecticut’s Ecology & Evolutionary Biology Greenhouses site: Kalanchoe fedtschenkoi.
