what temperature does bottle brush withstand?

Question

Is my bottle brush still alive after a winter in New Orleans this year after record cold temps?

Answer 1

Yes. You are within the hardiness zone, and rarely in history have the temperatures exceeded the lowest zone temps. This will survive down to about 15 degrees with some damage.
