'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.

Growing Info
Harvesting: Harvest leeks when tops are 15"–18" tall, and shanks are at least 1" in diameter. Use a garden fork to gently lift and loosen soil under the leeks, and then pull them up by hand. Leeks tolerate temperatures as low as 20°F, and can therefore be harvested even after a few freezes, which enhances flavor.
