Found these while mowing a backyard that wasn't taken care of for a while. Didn't know if they were real green onions or the toxic plant that looks like them because of how big they are. There was just a big patch of these and grass next to them, no flowers or anything else. Was wondering if someone could identify them and let me know if they are edible.

I would never eat anything I wasn't sure I could identify.

But, inquiring minds want to know, what do they smell like?

They do have an onion smell. When I was weed whacking they hit me in the face and it was very strong and noticeable.

Might be garden onions left neglected. Or ornamental onions.

Coincidentally, we have some onions growing in our lawn as well. Have no idea how they got there, they've never grown there for the two years we've had this house. And we're gardeners, so we don't leave our gardens neglected. Really strange stuff. The only garden the previous owners had was a few acres down the property, much too far for anything to have gotten to the lawn.

Johannian,
There are some very skinny wild onions we get in the lawn.. you dont mean those?
Allium vineale I think.

But these two weedy kinds are much thinner than the original questioned ones.

No, definitely much fatter than False Onion. It looks like they could maybe be big onions, not even green onions.

Seeds, they tend to wait til they think they can survive, then bam! your lawns are covered with onions. Those look like real green onions and as long as they smell strongly of onions, and weren't going to bloom purple scapes, you should be fine. 5 yrs since I grew night blooming morning glories, and this year they are coming up...

Well thank you all so much for your input I think im going to try a small bit and see what happens.

Great! Let us know how they taste.

I think it's wild garlic. Grew up with it all over my suburban Chicago yard. Dad even had a special patch in his vegetable garden. Tastes more of garlic, than onion. The city supposedly derives it's name from the French pronunciation of the Miami-Illinois word "shikaakwa", meaning "stinky onion". It grew wild all over the region. My sister had it growing wild in her LaSalle garden too. Use it, it's good. You only get 1 bulb with each stem though.

They are onions, if you like onions , eat them.

Onions! Garlic leaves are flat. Green Onions, as is already showing signs of developing a seed head. If in a tight clump we called them multipliers. Delicious spring and sometimes fall if the weather cooperates. Left over winter each will make more beside it. Wonderful -- in the right place. Like hide in the perennials and enjoy.
