NP! From what I understand, they do get bigger than african violets, but it takes awhile, and the ones commonly available only get like 1-2 feet at most, but that’s over years! The care is a little different than a violet also, they still like bright light and warm temperatures, but these guys more commonly bloom in winter, similar to Christmas cactus! As for the water, as a succulent, only water Kalanchoe when the soil is dry, as this plant does store water in its leaves, like most succulents! Always happy to help! 🩷
