Egyptian onions.
I am not growing bulb onions after this year. Egyptian onions are just too easy to grow and I never have to buy them again.
Pros:
Grows year round
Never have to buy again
Grow in pots and in ground
Requires very little care
Self propagate
Multiplier onion
Fire ants have yet to attack
Cons:
Not all the baby bulblets grow
Not bulbs
Not a storage onion
