the green onions, well I read somewhere(I'm terrible about giving people credit when it is due. It isn't because I'm rude, it's because I can barely remember where I live half the time) that you could grow roots on the bottom of celery if you placed it in a cup and gave it lots of light. It kind of reminds me of the sweet potato experiment when I was a kid. I'll keep you posted but my guess is this one isn't going to work. I will probably just grow slime.
Thanks for stopping over,
