It doesn’t grow here either. My grandma who was in Arkansas grew garlic, I think it needs both cool and dry, we have neither of those here.

Stokes Purple Sweet Potato though? It is like that. Chuck it in a pot of dirt, wait a few months, dump it out, full of potatoes. Okra, broccoli, cauliflower, eggplant, watermelon, all sorts of food plants I’ve had good results with but nothing that bulbs underground except those purple sweet potatoes.
