Europeans have savored the delicious flavor of leeks for centuries. Gaining popularity with gourmets and cooks in the U.S., this onion relative has compact stems that thicken but do not form bulbs like onions. The appealing white stems have a creamy yellow heart. Leeks are cold tolerant to 20°F and can be left in the garden into fall for an extended harvest. Also called Giant Musselburgh.
