That is really pretty, Ms. Kitty. I have been wanting to make one for years out of sedums. Maybe I'll get it done this year.
I've made wreaths before but never thought to use sempervivum. Looking at the way you've made yours up Kitty and how attractive it is makes me want to have a go at one myself.
They are really easy to make. I have made one before, but it died out during the winter. I think this one will be ok.
I bought one from a garden show and I tried to over winter it in the ground with snow covering it and it did not make it. All or most of my hens and chicks that are growing in the ground can handle the winter weather. How are yours held in the wreath form? One I bought used pins...which just rusted and looked terrible.
