Please help with flower identification

Hello all,

I found this plant growing in an untended bed in Chicago, IL. I think that it is a perennial geranium but I am not sure as most of these plants have five petals.

Thank you,

Alison

 

Would you be able to get a pic of the leaves? Looks like Malva sylvestris zebrina, normally 5 petals, however, there is a pic on the net which shows both 4 and 5 petals.

Malva sylvestris, the form commonly called "zebrina" in the trade.
