Lynn, Just read your biography of Peter Diekmann. He was far too young to have passed away -- and from what you have shared, was already heading up an unofficial Sempervivum Society.
Are you part of the "team" continuing to compile his Sempervivum "Liste?" Is this the place to continue building in order to have a "full-service" Society?
Lots of questions! And a sadness that I have just found semps and have missed so much!

MR
