Were you able to find any more info on those SUPERSEMPS? I haven't really, but I was able to find the Rose Quartz, Ruby, and Amethyst at a nursery up in Iowa during a visit in August. They're doing ok (I bought 2 of each just in case). Their tags were simply a barcode with their name (i.e. Sempervivum SUPERSEMP Ruby). They have a website where they offer them, plus one called Emerald, but only the Rose Quartz was in stock. They do not have much info about them either, basically a name and size.
They also had 2 of the Colorockz series, which also had barcode tags but theirs did not specify Colorockz.
