Positive	CurtisJones	On Sep 8, 2008, CurtisJones from Longmont, CO wrote: From your friends at Botanical Interests: Europeans have savored the delicious flavor of leeks for centuries, but they are 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 with a subtle onion flavor. They are superb eaten fresh, grilled, sauteed, and added to soups or stews. With a long crop time of 120 days (to get the largest stems), this is a great vegetable to start indoors early in spring when you are anxious to get back to gardening. Leeks are cold tolerant and can be left in the garden into fall for an extended harvest.
