Well.....as best able to make out from the picture and size being relevant to the finger in the picture....I'd have to say Malva sylvestris, noting the dark red veins, on pink or lavender flowers, common name High Mallow.

It does resemble cheeses or common mallow, but appears to have an upright habit, not creeping. 

Malva sylvestris can grow 1-3 ft high,  leaves are "broad and crinkly,  five lobed, ivy like..." It's bloom time would be June - August.
