This unknown plant has an interesting habit of growing babies all along its leaf edges. It also has lilac coloured bell flowers, although they have mostly faded now. This close up shows some babies along the leaf edge, there aren’t many at the moment, the plant makes loads along the leaf edge. After a while the babies fall off the leaf. The leaves are smooth and after ages, the older leaves get this veined cracked look. The cracked leaves are at least a year old.
@Palustris yes it is a kalanchoe, thx, further research on the net tells me it is also called "mother of thousands", thx to Elaine who suggested mother of thousands.
Wasn't certain that your plant was the same as the Kalanchoe daigremontiana, so I did not give its name.
Bryophyllum daigremontianum, commonly called mother of thousands, alligator plant, or Mexican hat plant is a succulent plant native to Madagascar.Wikipedia
