have no idea

some kind of nice flower and I have no idea what it is, maybe you know. anyway I made a picture of it because I wanted to find out what it is but then I forget about it and now I am too lazy :)
Photo is from Adamov (Czech Republic) where I grow up. Adamov is surrounded by huge and very beautiful forest. when I was little I nearly lived in the woods - after school and till sunset and every Sunday me and my family went on a walk, pick up nice flowers (spring-summer) or mashrooms (summer-autumn) or make BIG snowmen in winter.
