I've grown lots of stuff from overripe things in the fridge and cupboards (potatoes starting to sprout, sweet potatoes, a pumpkin I left sitting too long and the seeds started sprouting, garlic that started sprouting, etc.), but I never considered growing stuff from scraps. Great idea! I'll have to try it. I've been meaning to try this with a pineapple -- I hear you can grow a bush from the cut-off top of the pineapple. Mint also grows if you stick some mint sprigs in a pot of soil (don't put it in the ground -- it will take over.)
