Who knew garlic came in 200 varieties. One farmer at a local farmer's market has been growing quite a few varieties. The San Francisco Chronicle wrote an article about heirloom garlic which included this farmer and others.
If you are interested, there are links in the article to places to order unusual garlic varities on-line like ...
