Thank you Kevin for your quick help and assessment. We immediately informed the seller about this knowledge, he is checking his stock. Beatrix Bodmeier also knows and we are considering publishing a notice in the German Sempervivum List, because the wrong clone is unfortunately already proven to be in circulation. We have permission to link the entry to the German Sempervivumlist here

Kevin please take a look at Erwin's picture from 05/24/2019 The purple coloration comes through clearly here as well. What do you say, can this be your cultivar or is this unfortunately the mix up?
