The American Flag Leek, also known as Allium ampeloprasum var. porrum, is a member of the Amaryllidaceae family; this family also includes onions, garlic, and chives. This vegetable is known for its mild, sweet flavor, making it a popular ingredient in various culinary dishes such as Leek and Potato Soup. The American Flag Leek features long, white stalks with broad, flat, green leaves.
Growing American Flag Leeks is relatively straightforward; they thrive in well-drained, fertile soil with a pH between 6.0 and 7.0. They require full sun to grow optimally; however, they can tolerate partial shade. It is best to start the seeds indoors about 8-10 weeks before the last frost date; once the seedlings are about 6-8 inches tall, they can be transplanted outdoors. Space the plants about 6 inches apart in rows that are 12 inches apart to ensure they have enough room to grow.

How to Save Seeds
Leeks will not cross with onions, only other leeks so isolate by ¾ of a mile. There is no need to store overwinter simply leave them in the garden until the next year. If you have terribly cold winters you can always mulch them or hill up the dirt around them. Once next year arrives the leeks will produce an umbel which should be ready around the fall; once the umbel is dry pick them and rub them in your hands over a clean surface to release the seeds.
