American Flag Leek

American Flag leek is a classic heirloom variety prized for its mild, sweet onion-like flavor and striking appearance. This cool-season crop produces long, thick white stalks topped with dark green, upright leaves, and it’s commonly used in soups, stews, and sautés for its delicate taste. Known for its cold hardiness, American Flag leeks can withstand frost and even improve in flavor after a light freeze. Plants typically grow 12–15 inches tall and require about 100–120 days to mature, making them ideal for fall and winter harvests. They thrive in full sun and well-drained, fertile soil with consistent moisture.
