Egyption onions , as well as their cousin, Catawissia, does not produce
seeds. As the onion matures, it will forum little bubils on the top of the stalk. These can be removed to replant or eat. Yhese bubils are replanted in the fall. Each bubil will multiply underground and become three bulbs. I usualy
plant mine during October. If you leave the bubils on the
plant, the stalk will eventually get heavy, bend to the ground and the bubils will
plant themselves. That is where the name walking onion comes from. These are mainly used as green onions. After bubils form, the underground onions stay small but become stronger. They are very tastey in soups, casseroles or just fried.
And you do not have to harvest every onion. Let them go through winter underground and they will multiply fast. Once these onions are established, you will have them for life.
Territorial
seed company sells both Egyptian Onion and Catawissia. They also sell
potato onions. Its a bit expensive, but as I mentioned before, once you have them, you will have them for life. It seems more and more organic catalogs are investing in these onions. The onions are shipped out in fall as this is the best planting times. I am sure I will have a surplus of my walking onions, so if you contact me in the fall I should be able to send you some.
