Leeks' mild but rich onion flavor and cold tolerance make them a favorite in home kitchens and gardens. This onion relative has compact stems that thicken but do not form bulbs like onions. 'King Richard' produces extra long white stems early. Enjoy fresh, grilled, sautéed, and added to soups and stews. Cold tolerant to 20°F and can be left in the garden for an extended harvest.
