Unknown plant - better photo

The flowers look like impatiens to me, but the broad leaves with toothed edges don't match. Are the broad leaves from the flowered plant or from something else nearby? The leaves on the plant next to it on the left looks like impatiens though.

The broad leaves are a Campanula which flowers later. The leaves of the plant are quite small - you can just see them in pairs under two of the flowers. No, it isn't an Impatiens, though. It's a perennial and pops up each year..Thanks for the thought.
