This is a call to all you First Science readers out there who may know something about plants. I planted a leaf that was growing out of the side of a sweet potato in my kitchen. It has grown to quite a plant in just 2 weeks, but someone told me it was a fungus, someone else said a weed and someone else again said it was actually a sweet potato plant. Can someone tell me? If we can come up with an answer, I have some assorted sciencey things to give away.

You can see the video podcast of this plant here, or watch the embedded you-tube video below....
