The 'Huffies' as they're called, or Jovibarba heuffelii, are so different in the way they grow that it's worth finding out more about propagating them.
Unlike some of the other Jovibarba species, huffies grow in a cluster of crowns, sometimes getting quite large.
The fact that the roots are very fleshy and thick makes the clump rise up off the ground, and because of the size of the roots (and the fact that they grow much like a carrot) they need deeper soil than most other types of succulents which have fine fibrous root systems.
The colors of Jovibarba heuffelii are rich and intense; reds, maroons, purple, aquamarine blue and some even come in a golden yellow.
They are unique in the hardy succulent world - I've been amazed at how tough they are, withstanding very cold and snowy winters with ease. Even getting completely immersed in water and then frozen, something that will kill off many other types of even supposedly hardy succulents doesn't faze them.
Here's the way to propagate them. It's a different method than any other of the similar kinds of plants, because they don't produce chicks or pups like their cousins, Sempervivum or other Jovibarba species.
The roots are soft like a carrot that's been in storage too long; kind of rubbery. Start making the cut between two of the crowns with a sharp pointed knife, then tear it the rest of the way by hand.
Each of these sections will make a whole new plant. In time, say two to three years from this surgical procedure, they too will start to split.
