Rick...
People have been gardening all over the world without taking heat zones into consideration for plant selection for centuries. The concept of heat zones is relatively new when compared to thinking in terms of cold hardiness zones. I think that's why the information is not readily available.
However, with the links provided in this thread, I do have some new starting points for doing some research. Thanks to all of you for helping me along my way.
Smiles,
