What Makes Survival Garden Seeds Different - non-GMO heirloom seeds

American Flag Leek Seeds produce a reliable heirloom variety known for its long, straight white stems and attractive blue-green leaves. These leeks offer a mild, sweet onion flavor that enhances a wide range of dishes, from soups and stir-fries to quiches and fresh preparations. Their balanced taste and tender texture make them a versatile staple in the kitchen.

This cold-hardy leek variety performs especially well in cool weather and is an excellent choice for fall planting and overwintering in many regions. American Flag leeks continue to develop flavor as temperatures drop, allowing for extended harvests well into the colder months.

Classic Flavor and Reliable Growth:

  • Long, straight white stems with blue-green foliage
  • Mild, onion-like flavor suitable for many recipes
  • Consistent performer in cool-season gardens
  • Well suited for fall and winter harvests

Why Customers Love American Flag Leeks:

  • Excellent cold tolerance and overwintering ability
  • Easy to grow with dependable results
  • Versatile culinary use across many dishes
  • Attractive, uniform stems for home harvest

How to Use / How to Grow:
Sow American Flag leek seeds in early spring or late summer depending on climate. Transplant seedlings into fertile, well-drained soil in full sun. For longer white stems, plant seedlings deeply or gradually hill soil up around the stems as they grow.

Leeks benefit from regular watering and consistent moisture. Harvest as needed once stems reach the desired size, and continue harvesting through fall and into winter where conditions allow.
