What can I keep in pots thru the winter outside? I have rosemary, chives, rose of sharon and golden dew drop. The less I have to drag into the greenhouse the happier I will be!
The only plant you should have to bring in, and then only in the coldest of winter temperatures (in your climate), is the Duranta.
If the containers are small, you might consider protecting them from freezing solid, perhaps by 'planting' them...containers and all...in the ground for the winter.
Are you in the Savannah area, by chance?
