Peter, this is such an interesting dark colored sempervivum. I love both of the photos you entered. This one with the offsets really catches my eye because of the even darker offsets. Also very nice watermarks.

here you can see how dark it can be

Wow, great name for it. How big does this one get?

I have this one since late spring and it isn't yet full-grown; I guess it might become 3'' in diameter...maybe more;

We will have to wait and see. I am finding that most sempervivum can obtain even larger size if grown in the ground/raised bed.

it's like the fishes in an aquarium - the bigger the container the bigger the rosettes...at least till the reproduction;
