As far as hardnecks and softnecks doing good here and not there. Most will grow anywhere but may do better than other places. Music is a good all around variety as well as Chesnok Red.
I have been gettin more into the Creole types. Which are said to do great in the deep south. I haven't seen anything on them anywhere but deep south in descriptions etc. Yet I grew them and they did great, oh yeah where did I get them, from a farm in Minnesota, so go figure.
