Hello there my favorite forum in the world.

Does anyone know what the name of this plant is? My family and I cant figure it out. We are in love with this plant. It is the coolest one on the whole back porch. This plant lives in Illinois now. It's from my grandfather that lives in Texas. A seed shot out one day and now it's a plant, so I have that inside my green house in Chicago now. We all love it. We see it as my grandfather.

Anyone have any clue? they have been calling it a potato plant and I said no it's not a potato plant :)
