lovesblooms, do not count it out as dead yet. There are many hardy succulents that resemble the tender succulents. The many hardy succulents go dormant in the winter but come back in the summer. So watch them this summer and see if it comes back. It could be a imposter of Audrey's tender succulent.
Audrey I would not suggest you put your plant outside for the winter it probably would not hold up with any temps below 60 for any long period of time.
Jean they are happier in cold weather if they are hardy but a tender will not be happy if you let old man winter have his way with a tender succulent. I know from experience.
