Puzzle in the Evening Sun

I have always loved Forget-me-nots but since I started learning to identify wild flowers these innocent looking blossoms have really given me trouble and headache every year. Even in Finland there are several species and they are really difficult to identify exactly. I think this is Myosotis sylvatica, puistolemmikki. I know three smaller species which this definitely is not, I suppose that is already something to be proud of.

I also back-blipped Happy reunion with a relative of Forget-me-nots yesterday.
