Yowza, that's almost 30 degrees colder than it got here, I'm sure that's a huge difference. I hope you are pleasantly surprised!
I took the sheets off the mini and there are a few losses, in the most exposed corner but not different looking enough overall to bother with a pic yet.
A Portulacaria afra and Sedum rubrotinctum look dead. Ever so gently touching leaves of Peperomia rotundifolia caused them to fall off, probably a sign of mortality. Definitely damaged but unclear if dead or alive: Schefflera elegantissima (a false Aralia cultivar,) Alternanthera ficoides, Iresine, a NOID Sedum(?).
Am I wrong to hope most Sedums could grow back if the roots weren't actually frozen, or am I mixing it up with tough Hylotelephiums ('Autumn Joy' and that ilk) too much in my mind?
Everything else has a normal color & texture, so far anyway. Definitely the Haws. Wish I knew if they actually froze or not, and if, like I expect for unknown reason, they would be mushy pudding already if damaged. The wall/window it's near couldn't have helped much, we closed off that room & it got down to 47 in there.
