The little green onions I refer to are about the size of a matchstick. They are often sold at garden stores for planting. Onions are biennial and if they think they are in their second year because of a stop in their progression, they will bloom. Perhaps it has some to do with size too, because it seems the small dry sets don't bloom, but larger ones will even though both are in their second year.
Some varieties of onions never bulb and are called bunching onions. They grow like chives. You would never know if that was a green onion you bought in the grocery store. You just have to plant and see what develops.
Also there are long day onions for the Northern states and short day onions for the Southern states. If you plant the wrong variety for your locale, you may be disappointed.
Save onion seeds? Yes indeed!
