“Among the Crassulaceae, the genus Bryophyllum is best known for many of its species having the ability to produce plantlets on their leaves. Although this ability is unique to Bryophyllum, only a few species in the genus and their hybrids have the ability to do so. It is not found among all the species of Bryophyllum. Some species of Bryophyllum produce plantlets on the floral stems instead.”
