Porcelain garlics generally have 4-6 large plump cloves per bulb. The bulb wrappers are usually satiny white with brownish clove skins. They are strong and flavourful, and  good keepers. Some of the porcelains, like Susan Delafield's, do well in wetter conditions. Porcelains are well adapted to colder climates. If the scapes are allowed to mature they produce hundreds of tiny bulbils that, if planted, can produce full sized garlic in about three years.
