I started gardening this year and instantly became obsessed. Next year I want to take my gardening obsession to the next level and sell my produce at a farmer's market. I've never grown garlic before, but I'm eager to try it because I hear it is a good seller.

I live in a suburb 40 miles north of Atlanta (zone 7b). Winter in northern Georgia tends to be mild and summer tends to be hot and humid. The soil in my backyard is very rocky red clay. Of course, I can easily amend the soil if necessary.

I want to choose a variety of garlic that will thrive in my environment and also bring in the most profit. Which varieties would you recommend?
