Zaubergarten,
I've had this sempervivum for almost 3 years. It was labeled Sempervivum Banderi. I think this is incorrect. I would like to find the correct ID but have never seen any photos of semps similar to this plant.
Your photo of Hodi's Ampel looks very much like my unidentified sempervivum. Do you think it could be Hodi's Ampel ?
