drake,

Where in FL are you? Did you get into upper 20s, low 30s? If you got that cold, it could be frost damage. Likely the tips will turn black and slough off. You will get new growth and maybe some branching just below that, but thnew growths will not bloom until it matures -- maybe late in summer for you. Photo might help.

Hi
Sounds like frost damage . About all you can do is trim off the damaged parts and hope it recovers. I've had them killed roots andall at 27. Usually recover from frost though gary

I agree with frost damage but I wouldn't be so quick to trim the plant back. Like Dave said if it's not too bad the damaged part will die back and drop off. If you do end up having to trim the plant back dust the cut end with a fungicide. Some people also seal the cuts with silicon caulk after it's been dusted and dried. Good luck.
