One of my very favorite crops is Egyptian Walking Onions. They are also known as Tree Onions, Top Onions, Winter Onions, or Perennial Onions. Whatever you call them, these onions are the perfect survival crop! Walking onions are simple to grow and, once established, never need to be planted again. It doesn’t take very many of these to provide all the onion flavor you could possibly need.
Green onions are a great source of Dietary Fiber, Vitamin A, Vitamin C, Vitamin K, Riboflavin, Calcium, Iron, Potassium and Manganese. If that isn’t enough they are a fairly good source of Thiamin, Vitamin B6, Folate, Magnesium, Phosphorus, Zinc and Copper. They would make a flavorful addition to dried food storage items such as rice and beans.
I like to dry these mildly flavored onions to use during the cold winter months. The process is incredibly simple. Wash, slice thinly, and dry. Use a dehydrator if you wish, but they dry very nicely in an unused vehicle in the sun.
