Product Overview
American Flag Leek is a cold-hardy heirloom leek that grows tall, thick, creamy-white stalks (15–18″ long, up to 3″ wide) under broad flat blue‑green leaves. It matures slowly (typically 90–120 days, depending on the source). Its flavor is mild, sweet, and slightly onion‑garlic-like — refined and not overpowering. These leeks are great for soups, stews, potatoes, and more, adding a smooth, mellow note without harsh bite. The variety is known for its winter hardiness — it can tolerate cold temps, even down to around –12 °C. Leeks are harvested by lifting with a fork when the stalks have thickened, and their long, stand‑up foliage makes them easy to manage in the garden.
