The Large American Flag leek is a popular variety known for its long, thick white stalks and vibrant green tops. Thrives in cool weather, making it ideal for planting in early spring or late summer for a fall harvest.

Characteristics:

1. Growth Habit: Large American Flag leeks grow upright with a sturdy structure. They can reach a height of 12 to 24 inches, depending on growing conditions. The leaves are broad and can spread out, requiring some space between plants.
2. Stalk Quality: The stalks are long, white, and cylindrical, often exceeding 12 inches in length. The white part is tender and mild, while the green tops can be used in cooking for added flavor.
3. Yield Potential: This variety is known for its high yield potential, producing multiple stalks per plant. Harvesting can typically occur 90 to 120 days after planting, depending on growth conditions and planting time.
4. Harvesting: Leeks can be harvested when they reach a desired size, typically when the stalks are about 1 inch in diameter. They can be left in the ground longer for larger stalks, but care should be taken to avoid bolting, which can occur in warm weather.
