Those are wonderful Shaw. I really like your 'dragon'.
It is getting ready to bloom, that is why the center of the rosette has grown like that. Once the rosette blooms it will die. But just look at all the offspring it is leaving to carry on.
Your hen and chicks seem to be one of the Jovibarba types, with the common name of 'rollers', because the little offsets can detach and roll away from the mother. They are very hardy and so much fun.
My favorite photos is the first one, with the very large rock with 'rollers' growing all over it.
They all looks so healthy and happy.
When the bloom opens you will know for sure if it is a Jovibarba or Sempervivum.
This is what a Sempervivum bloom would look like, open star like shape. Pink, red, rarely white/cream.
This is what a Jovibarba bloom looks like. It stays in a tubular shape. Pale yellow, almost white.
