I have that Kalanchoe daigremontiana Jelinda. It makes its babies at the tips of each leaves, once it matures, it can easily drop off around and thus propagate itself. It hates being wet and cold but resilient enough to bounce back once warmer weather returns. It is considered very invasive in warmer areas. Mine is somewhow controlled by our cold winter rains. But this year a bit drier winter, it has managed to maintain its growth. It does grow very tall, loves full sun.
I think having 2 plants in a pot is already enough, it multiplies very fast. My container originally just have one, and now it has 4 and more coming about.
