Is this a mallow?

This picture was taken in July or early August. It's in partial light shade. I think it might be some kind of mallow. Any ideas?

I think that looks a lot like an Althea. You call them hollyhocks I believe.

 

If so I hope I can figure out the species or cultivar, as I want it again next year if possible.
