Lovely flower

I have no idea what kind of flower this is! I emailed the picture to my friend Ruth and text her to ask what it is called before I downloaded it, but no reply so far, she must be working a late shift!

I got up early this morning, went for a lovely long walk before I had to go to work. I tried all different types of pictures and my son picked this one as the best. Hopefully I will be able to add the name soon.... thought it was lovely, it was all on its own among lots of weeds and trees.
