Hey TK. I dunno if store bought wild onions produce little jiggers like that but i'd suggest you take them, dry them out and store 'em in a dry cool place till next season and plant them out. I reckon they'll grow again when the soil warms.

The green onions in my yard propagate in two ways:
1. As TK mentioned, the bulbs divide over the winter. They get nice and fat over the summer, and in the spring 2-4 green onions sprout from the 1 bulb.
2. Depending on the variety, they will either flower and set seed or produce a scape with little bulb-letts once it gets hot.

We had a week of 70s and 80 in April, and my green onions are already producing the scapes. The scapes are woody, so they are past their prime, but I can plant the bulb-letts for a summer/fall crop.

Composting is more than good for your garden. It's a way of life.

Well as Weezie said the easiest way to identify them is by smell. lol

They are alittle more blue green than the ones in the grocery store when they get really tall. Other wise they look like a chive on the stock. Alittle more waxy before they are picked than papery. But I have noticed that in the crisper for a few days and the leaves do turn papery.

The white part that is below ground is a bulb shape. The smaller the rounder. It slims down the taller they get. The roots look just like in the store bought ones.

I hope this helps. The smell was more pronounced once I brought them in the house. But I am a smoker so that might have had something to do with it.

I tried wild onions for the first time just a couple of weeks ago. (In fried potatoes) They were really good!
