Anyone know what this flower is???

I was cleaning out some things today and I came across some pictures of my grandparents in Missouri from a few years ago. In one particular there are some very beautiful flowers. They plants stand very tall and the flowers are huge. I was wondering if anyone knew what they are called or anything about them in general. Please take a look at the picture in the cut. Thanks for your help??
