EGYPTIAN WALKING ONIONS / PERENNIAL OR WINTER ONIONS / ALL ABOUT EDIBLE. Also known as top onions, tree onions and Egyptian tree onions are edible from the bulbs to the greens up to the topsets or bulblets. This onion is wonderful to grow in the garden, plant it once and you will have a supply for many decades. That’s one of the reason why I grow a lot in our garden because I regularly use onions in my daily cooking. We hope you enjoy watching this video.
