Ever wondered what an onion flower looks like?

In my winter garden last season, I planted some green onions.  They were plentiful and definitely more than I could use.  I was really curious to see what an onion flower looks like as I have never seen one….. so I let one bunch flower and go to seed.  I thought you may find it interesting as well so I took some photos.

Here are what the flowers look like.

These flowers have been growing long enough that the seeds are inside.  If you squish the flower parts with your fingers, you get seeds out.

and here is a photo of the dried flower so the seeds are really obvious.

Anyone know if I can plant these?
