I had a brown onion from the store that began to sprout. Rather than eat it, I decided to plant it in the vegetable garden. So I could eat it and all of it's children. Muuhahahahaha!
Ahem. Sorry about that.
Err, as I was saying, I planted it and it recently bloomed. The flower is perfectly spherical, one of the strangest flowers I've ever seen. It looks like this.
