Hi there!!!
I just recently came across an onion in my pantry just like yours! I let it grow in front of a sunny window and, like yourself, wondered if I could
plant it. Nobody seemed to know the answer, so I just let it stay in the sunny window unplanted. Then I got a magazine in the mail a few days later and it had a picture of an onion, just like our onions, and it was sitting in a glass of water with the greens shoots at the top and white roots
growing into the water. So, naturally, I ran over to my onion, stuck toothpicks in its side, and sat it in a tall glass of water and put it back in the sunny window. The very next moring it had 2-inch long white roots, and now, about a week and a half later, it's still
growing and has yet to form a
flower.
I was wondering, would anyone care to share how to grow actual onions for eating? Would I be able to use parts of this onion I have
growing after it
flowers and I dry it out?
Good luck with your onion!!!
