Thank you for the info Tarev.
A few times this winter in was in the teens, but mostly in the upper 20's and low 30's for the night time lows. A few days that stayed in the freezing range.
This winter I decided to see if some of mine would make it through a winter outdoors. I put them on our covered deck where the rain wouldn't get to them.
Here is the results. I am pleasantly surprised.
Echeveria derenbergii Lots of dead stuff, but the rosettes laying on the potting soil look very healthy. Looks like some of the stems are still alive also.
Graptopetalum paraguayense Appears to have made it in relatively good shape.
These three I don't have an ID for, but they made it.
I can't believe this one, it looks almost the same as it did this last summer?
