Karen, I keep my indoor temps at 68F, that's about what I compromise with. Yeah, this plant is teaching me to be very patient. I was so tempted to pull it out before but then I realize it was reacting to our very long dry season and it really likes the comfy warm 70's to 80's with some rain. I don't bring this one in, just the other tender succulents. It does respond to that nice pruning.
Vicky, your growing area is much different than mine, so I do hope you can try and prune a bit and find a warm, comfy area indoors for it to grow during cold season.
