Sweet Potato

I fell in love with pictures of the sweet potato vines. I never grew potatoes before so I tried to get starters. I tried at Burpee but they do not ship these to Florida. So I asked several people at work and they all said stick it in the ground. I purchased one at the grocery store and I put it in a pint sized canning jar with water and put it on the kitchen windowsill. It sat for a few weeks with nothing happening. Then I noticed roots growing and leaves pressed against the glass. I planted it and it has grown so much that a larger container will be needed.
