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 exceptionally well in extended seasons and can even withstand frost. 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 must-have addition to any vegetable garden, offering a gourmet touch to your culinary creations.
Leek - American Flag - Allium ampeloprasum
Biennial Heirloom. A perfect variety for the home gardener. American Flag has thick blue-green leaves with large white stems. This variety is good for fall and winter harvesting and will grow quickly from seed. Delicious in soups, stir fries and stews.
Did You Know? The leek is an ancient national symbol of Wales. In fact, a leek is the cap badge of the Welsh Guards, an infantry division of the British Army.
Soil and Water: Leeks prefer well-drained soil rich in organic matter. Keeping the stems covered with loose soil will keep them bright white.

There are very few products out there that you buy once and it will keep on serving you. These can be reused year after year instead of ending up in the garbage can or landfill, so good for you and good for the environment. You pay a little more, but you save over time. I am absolutely sold on Bootstrap products.
What I like about the kit is that the plastic trays and dome are made of a very sturdy material, not like the flimsy trays I have used in the past. It was difficult to move full trays when they were not rigid. These trays are quite rigid and I think will make moving them much easier. They also seem like they will hold up longer with normal usage.
It was convenient to get everything I needed for a small seed starting in one package and I didn't have to search around for all the parts. It has the mesh bottom insert that seems to be necessary for use with soil blocking, so that was a big plus to me.
I am going to try the soil blocking, so I'm excited to try the blocker. Just getting everything set up now. However, the blocker seems to be in good working order even though I haven't actually used it yet.
One thing I think would improve the website is mentioning in the item description that the plastic is much sturdier than ones mostly seen in the stores. I wasn't quite sure that it was the sturdier version, but I decided to take a chance. Just making that clearer in the description would have been helpful. (i.e. "these trays and domes aren't the flimsy version you find in most stores!") I am sure people more used to using greenhouse products know that, but people new to that might not.
