Potatoes Growing Indoors...

This is actually kind of funny! I had a bucket of potting soil outside and brought in inside - was thinking I might need it. I like to start seeds indoors etc - well come to find out , my son, had dropped a tiny potato into the bucket of dirt a couple of weeks ago!! It is actually growing (sprouting?). My son thinks it is so funny. Is it actually growing to where we would get some more tiny potatoes?? It was one of those gemstone potatoes from Walmart. haha
