Here is hoping you didn't lose anything that was very special to you. I hope you left only duplicated plants (or easily replaceable ones) out in the cold temps.
I am also guessing that was abnormally cold for your area?
I have left duplicated succulents out and am curious to observe them. Some are in containers, others in a raised dry bed. The lowest temperature we have seen this winter was 24 degrees but the next few nights will tell the tale. Expected to drop into the high teens. And I expect the lows aren't as critical as the length of time spent at those temperatures.
C'mon Spring!
