Hi Janinebrink, and
to ATP.
Great photo of Sempervivum globiferum. There are many different types so it would be pretty much impossible to know which one yours would be.

It does appear to be one of the hirtum types.
Love you photo. Is this the only Sempervivum you have? Where do you live, your colony looks very healthy and happy.
