Hello Wren and
! No worries about long posts, I tend to do the same thing
the more information the better! Neat that you are from North Carolina. One of my grandmothers was from the coast of NC, and cried when she first arrived in California because everything was so dry and brown.
it is very easy to get addicted to sempervivum. I only had Sempervivum tectorum and a few mystery ones, and all it took was finding Mountain Crest Gardens and some other places for me to buy whatever caught my eye. Funny you mention being turned away by the cilia - I remember seeing an arachnoideum once when I was little and not wanting to touch it because I thought it was infested by spiders
Hopefully you can find chicken grit or pumice! Where I live, no one close to me has any of it available
if our climate was cooler, I suspect sempervivums would grow happily here in our soil, mostly deep rocky sand with some underlying sandy clay in places.
again and can hardly wait to see photos once you have everything set up
