I believe they are rated ok down to Zone 7.
Please note that my zone is 10 to 11
my big concern is overwatering during a winter, last 24h we had over 30 inches of rain in one day, plate is off , but ground in the pot is totally soaked in water. Next week should be no rain, I hope soil will dry a little bit.
