Sister, Just wanted to add, from a technical point of view, that many professionals consider that Jovibarba should be actually Sempervivum as well. The various Jovibarba species are considered subspecies of Sempervivum. The professionals that work with stuff, from time to time, change their opinions as knowledge increases. Jovibarba have been Sempervivum before and this has changed.
So why do we need to know this? Well, you may come across a name of a Jovibarba that is called a Sempervivum or the opposite. We're just hobbyists, so we go with what we know.
