They grow anywhere from Florida to New York to Texas so you should be able to grow them where you're at. I'm in zone 7b so to recommend the best cultivar to grow I wouldn't be able to help you out with that. I went out and found the largest one I could find growing in the wild and got cuttings from it. If you can't seem to find one or find cuttings where you're at I'd be more than happy to get some to you!
