Hi Sunlover, and
to ATP. So glad you found your way here.
I agree with Bev, your new sempervivum does appear to be of arachnoideum heritage. It is lovely and healthy looking. I also agree with that you can either divide it or plant it as a clump. Maybe take a few of the offsets and start a new colony?
It also looks like you already have a wonderful feel of how to grow them in your part of the world, your other semps look healthy and happy.
Here are more photos of S. 'Flamingo'. It goes through some interesting color changes. Would love to see more photos of it as it changes color.
