Just recognized the name of our purple-striped variety in abhege's post above: Chesnok Red. Or it may have been Killarney Red. Hmm. Wish I'd been better about keeping them separate and labeling them after the first year!
I found labels for 5 of the 8 varieties I grew:
Killarney Red: Rocambole garlic, very hot pungency, stores 5-6 months.
Chesnok Red: a Purple Stripe garlic, medium warm pungency, stores 6-8 months
Siciliano: an artichoke garlic, medium warm pungency, stores 6-7 months
New York White: an artichoke garlic, very little pungency, mellow flavor, stores through fall into winter
Georgia Crystal: a porcelain garlic, mellow flavor, slightly warm pungency, stores 8-10 months.
I ordered them through Gourmet Garlic Gardens in Texas, but they have changed their ordering process. The used to offer collections directly, and now feature several collections, and then provide information on several different growers from whom you can order that collection. Some collections are based on flavor, while others are for specific geographic areas or temperature ranges.
I do recall that I emailed Bob with some questions, and he was very friendly and helpful! I think what I got was the Garlic All Year Round sampler, and specified a mixture of mild to hot.
Mmm, now I'm craving garlic bread. . .and I think I have half a loaf of homemade sourdough bread.
