Thanks sachsblau !
Here are three Sempervivum that I grow in a garden in the Drôme Provençale, France. They begin to make offsets after three years, although the conditions are harsh for them. Little soil, plenty of sunshine, heat and very little water ....
calcareum Tête des Mines, 885 m, Mont Ventoux, Vaucluse, France
tectorum Embrun, Hautes -Alpes
x funckii Prinz-Leopold-Platz Schlossturm, Bad Berneck, Germany
This last plant is a introduced plant in different German places. Unknown origin.
