You’ve probably heard the term ‘Mother of Thousands’ (or ‘Millions’) used for several plants by now. It’s a common name given to the varieties of Kalanchoe/Bryophyllum that reproduce by plantlets called bulbils that form along the leaf margins. Bryophyllum is another genus given to this type of plant, but it most commonly still referred to as Kalanchoe. Some botanists group Bryophyllum with Kalanchoe.
