Green onions add a lovely bite to dishes. The next time you cut them up, hang on to the scraps, and grow some of your own in no time.
You know those little end pieces with the roots attached that you probably just cut off and throw away? That's potential you're chucking out -- the potential to grow brand new onions in nothing but a glass of water.
The folks at WonderHowTo point out that all you need to do to regrow your own green onions is pop those root tips in a glass with enough water to cover up the ends. Green onions grow fast, so you'll likely have new ones in a matter of days. When you eat the ones you grow, you can start the process all over again with those scraps. Green onions forever!
