We used to get white, red and yellow onion sets and plant them. I have never been a big fan of onions but, I did eat some of the onions we grew. And the onions were stronger smelling than the ones we got in the store.
I liked that I did not have to worry about if a seed would sprout or not. The onions were pretty much guaranteed to start growing.
I also remember planting onions from seed which took a lot longer to get an onion to maturity than from an onion set. At least I think it does. I am not sure how much longer though.
I think from seed I might have grown walla walla onions. I am not sure if any of the onions we planted from seed ever got big or not.
Anyway it would be nice to have a sandwich with fresh cut onion, lettuce, and tomato.
I will have to grown onions again.
