- 🌱 The plant is native to Madagascar and was introduced to Europe in the 1930s, becoming one of the most commercially successful potted flowering succulents worldwide.
- 🌱 Kalanchoe leaves are capable of vegetative reproduction—a single detached leaf can regenerate into a new plant, making propagation extremely easy for gardeners.
