Peter, do you know why the Sempervivum and Jovibarba will not cross?

that's the difference between the nixonii-groups - Jowan is a x nixonii (x nixonii) and Feuerrad is a x nixonii (x smithii);

I don't know enough about genetics to understand why Jovibarba and Semps will not cross; I only know that there is no example where it works;
