It is beautiful but very variable and offer a huge diversity of shapes and sizes, the more common form has wide, grey-green, plastic-leaf form with bright green colouration and pink-purple margins. It produces annually 2 to 4 long stolons (like strawberry) with baby plants at the ends of long stems, which eventually trail attractively over the containers edge and bend down to the ground and take root, giving rise to its common name of "walking kalanchoe". The stolons produce themselves other stolons and forms large carpets of rosettes of various ages and sizes.

The leaf size and colour are variable, which results in a number of selected cultivars.
