It looks like Germany Hardy, German Extra Hardy, and German White are the same.

Note to Worth: this one mentions Florida and South Texas as hard places to grow certain vars.
Kettle River Giant is one of the artichoke types and can be grown further south according to:

They look big!! Grow these and make us all jealous.
Our New York White btw is also a softneck and quite a decent garlic to grow, but not as big as the Kettle Creek!
Spanish Roja is the only rocambole I've tried yet... delicious and really nice. It did well at the farm, so I hope it's just a little later here.
There's another rocambole, recommended for northern situations called Italian Purple or Purple Italian - there's also a softneck by that name so wondering if PMCGrady has the rocambole or the softneck? Let us know how they do pmc.
My thought, as with tomatoes, is to try out as many as feasible, and find which ones can tolerate my situation. Thick with white frost this morning.... shockin.
