Poor little guy! The things we do for kids...but they're worth it!
I had onions go to seed and they were IMO pretty. I had onions coming up every year for the rest of the time I was there and I purposely let them go to seed. After I left my planting beds were planted with grass and I've wondered if they still have onions coming up.
This is the last time I'm frogging this project for the last time.
