This is indeed a Kalanchoe – K. fedtschenkoi or Lavender Scallops. This one looks like it needs more light – they like it bright! Full sun outdoors, or in a bright sunny window inside, or better yet, a grow light especially in the winter.
If the light is bright enough, and your summer is hot, they will change color to a gorgeous purple tint. That’s when you know that they’re truly happy.
All Kalanchoe have some unique characteristics; a lot of them show the same kind of scalloping on the edges of the leaves, and they all seem to have incredible flowers of the dangly bell sort.
