Can anyone Id this flower?
It's a mallow.



The leaves - they look like maple leaves - and the flower are identical.

Mallows are from the family Malvaceae, which includes food plants (okra, cocoa beans, kola nut), economic plants (cotton), and ornamentals (e.g. hibiscus) One species of this family (Althaea officinalis) is actually the original ingredient to make marshmallows.

I'm not sure which mallow it is (there are 243 genera with 4225+ species), but it's a common weed wildflower all over the world.
