Potato Plant Flowers

A little while back I planted some seed potatoes in a huge concrete pot that I had sitting empty for quite a while. I wasn't sure is it was a good spot for them, but I wanted somewhere where they would be contained and tires just didn't work for me.
This morning when I went outside I got such a lovely surprise. They have all started flowering, and it's looking stunning. Who know that a simple potato plant could be so beautiful!
