I am just going to go with Pachyveria Superfatii (yes I just made that up)
. In the cold weather the leaves are turning an amazing pinky mauve color. Just gorgeous. The leaves that detatched during shipment are starting to grow roots so fingers crossed I will have a few new ones come spring and maybe a flower to help ID.
It is most def a xpachy, not a xgrapto and will be treated as such.
I have never seen a xgrapto with leaves this fat and rounded. I would bet it's a cross with a Pachyphytum Oviferum and a white type of Echeveria like a Lauii.
I just ordered a couple more succulent NOIDs because I am a masochist. Can't resist a good mystery. I'll keep you updated on this one!
