We get in the 20's here too, and we're now considered 7b instead of 7a. This past winter was the coldest and wettest for the longest ( how many "ests" LOL) that I recall in years.
I do have 1 succulent plant that was left outside all winter, and it survived, surprisingly. I'll have to figure out what kind it is. I'm not brave enough to leave the epies outside yet. They'll be taken inside to the basement in October or November.
How old is your oldest epie?
