WOW! The next time you have green onions, don't throw away the white ends. Simply submerge them in a glass of water and place them in a sunny window. Your onions will begin to grow almost immediately and can be harvested almost indefinitely. We just use kitchen scissors to cut what we need for meals. I periodically empty out the water, rinse the roots off and give them fresh water.
Seriously the most simpliest yet coolest idea ever. I made these for my boyfriends birthday morning & he loved them! Came out perfect! No special requirements that aren't already on the package c: *Although I recommend spacing them out.
