@mrmaple! You're gotten a great case of Sempervivitus! Where are you located?
If you can travel you should plan to come to the Kevin Vaughn Hybridizing Clinic April 26th to 28th, 2019 in Oregon.
I'm pretty much a semp newbie, but I'm hooked too. They're fascinating, fun plants!
I'll let the others give you more links and info.
