I would love to grow this here but from what my understanding is, I'm right outside of the zone of where it would grow. We are near Raleigh NC area. Do you know of any tips that might make it worth a shot? I have a wooded swamp area and was thinking to build a hugel at the edge of the swamp and growing it there. I'd build it high up enough that it was not getting soggy wet. The micro-climate would help keep it cooler.....do you think it would work?
