Hmm, maybe those two are thinking about blooming. Please keep us updated on their progress.
Do you ever get fasciated offsets from your 'Fuzzy Wuzzy'? It is very common in this sempervivum.
If you look close at your 'Fuzzy Wuzzy' photo, it looks like one of them is starting to do the same things as the two 'Bronco' plants. What do you think.
I think I know where you are. I did not realize your growing zone was that warm. For some reason I thought you got much colder.
