Sometimes called Aglio Rosso, sometimes Rosso di Sulmona. "Aglio" is just Italian for "garlic," the rest means "Red of Sulmona." I've grown Rosso di Sulmona for a year now, and I'm impressed by its vigor as a Creole. It's tough to get Creoles big up north but this one's been doing pretty good. 12-13 cloves per bulb.
PS- I bought and grew an "Aglio Rosso" and a "Rosso di Sulmona" separately, but have heard from authoritative sources since that they're one in the same. The photo for this is the stock I'd labelled "Aglio Rosso"
