House Leek

Sempervivum arachnoideum.

Yesterday Blipper John39 featured his House Leek in flower. It had put up a single tall stem with flowers at the top.
As you can see mine has done the same.
Apparently each rosette will take its turn at sending up a flower and when it has done so it will die leaving room for a new rosette to grow. I do not know whether you can get several flowers at the same time. Timewill tell.

Curious and interesting.
