Bonnie Plants Leeks is an heirloom member of the onion family... the gourmet’s onion because of their mild flavor prized for casseroles, stir-fry, soups including classic leek & potato soup, and omelets.
This version, called American Flag, is one of the favorite leeks for home gardens. Plants grow nice, 10-inch-long, white stalks about 1 to 1 ½ inches in diameter. American Flag is a frost-tolerant, cold-hardy leek, making it good for fall planting in zones 7 and warmer, easily growing where temperatures don’t drop below 10 degrees in winter, but they take longer to grow to full size. This also goes by the name Broad London leek.

Quick Guide to Growing Leeks
- Plant leeks during the cool weather of early spring and fall. They grow well in raised beds, containers, and in-ground gardens.
- Space leeks 6 inches apart in an area that gets 6 or more hours of sun daily and has nutrient-rich, well-drained soil.
- Improve native soil by mixing in several inches of aged compost or other rich organic matter.
- Leeks aren’t fussy, but they do require moist soil, so check soil moisture often and use a soaker hose if necessary.
- One week after planting, begin regularly feeding with a water-soluble plant food.
- Harvest leeks at any time once they are large enough to eat.
