Answer: This plant is considered winter hardy into the warmer part of zone 9, where winter lows might be just a bit below 30 degrees at worst. So, depending on how cold it actually was, it might survive. I have accidently left this plant outside where it became frosted, there was damage to quite a bit of the foliage and stems but it did survive. The cold damaged portions discolored and went soft/mushy and had to be trimmed off. (This plant can be pruned quite hard if need be, so trimming it is not going to kill it although it may look terrible until it grows back.) If temperatures were below about 25 degrees though I would not expect it to recover. At this point the best you can do is keep it in a bright window, water sparingly, and hope for the best. Remove any parts that turn soft. Even if it survives, it may take it quite a few weeks to begin to grow again since we are getting into the shortest days of the year. Good luck with your plant!
