Silverskins are the lesser known of the two Softneck families. In my experience so far, Silverskin plants are larger than Artichokes. Even longer-keeping than Artichokes, Silverskins are said to keep 10 to 12 months in ideal storage. That means your own independent year-round supply of garlic! Silverskins have a large number of cloves per bulb, easily 12 to 20 per bulb. Good for making sturdy braids of garlic as well!
