$3.99

American Flag Leek is a classic heirloom variety treasured for its thick, tender stalks and mild, sweet onion flavor. This versatile vegetable adds depth and aroma to soups, stews, and sautés while serving as a milder alternative to traditional onions. Growing up to 12-15 inches tall, these leeks thrive in full sun and nutrient-rich, well-draining soil. They require a long growing season of about 120 days, making them ideal for fall or overwintering harvests in cooler climates. Known for their cold-hardiness, American Flag Leeks perform well in extended seasons and can even withstand frost.

For storage types, allow curing after the neck and outer layers reach an appropriate stage. The plants have a compact, upright growth habit, making them suitable for small gardens or interplanting with other crops. With their easy cultivation, long harvest window, and delicious flavor, American Flag Leeks are a useful addition to any vegetable garden, offering a gourmet touch to your culinary creations. Before sowing American Flag Leek, review the packet alongside the current product details and note any range in temperature, germination, or maturity. Ranges reflect biological and seasonal variation rather than a fixed promise. Label each planting with its date and location, then compare emergence, growth, and harvest with local weather. This record is useful for succession plantings and for deciding whether the crop fits better into an earlier or later seasonal window. Explore related options in our Leek Growing Guide.
