Found this idea in the magazine, Eating Well.
"Next time you buy scallion,s don't use the whites - sprout them. Simply secure bulbs with a rubber band and place in a glass with an inch of water. Change the water daily and in about 7 to 10 days new shoots will appear and the roots will double in length. Plant them in a garden or container and snip the greens as you need them."
