It's very difficult to grow artichokes in Georgia.
They require a long cool growing season, which of course we don't have. But also they don't tolerate freezing weather well at all.
Artichokes are a biennnial. There is a variety, Imperial Star, that supposedly can be grown in one season, and is more adapted to the south. I haven't tried that particular one.
Long time ago I tried, and just didn't have any luck with them. Maybe in a partially shaded spot, with a real good water supply.
