I live in East Tennessee. Zone 6b. Our lowest winter temps are usually about 10 degrees F ( -12 C). Does anyone know of a plant that would grow here and produce caffeine?

I have been told that Camellia Sinensis (common tea) will grow here, but this is only marginally true.

What else is out there?

Thanks, Mike

P.S. I know about ephedra. I am looking for caffeine plants only.
