It looks like an honesty that has been munched by catepilliars. To the right of one of the pictures it looks like you've got seed pods forming.
From your pictures this looks like this years growth that did very well and threw out a couple of flowers. Honesty are really tough plants and grow wild. I don't think you need to do anything as they are really hardy, The risk taker in me would probably cut them back a bit in the hope they grow to their full potential next year.
There's some self seeded honesty here that are in flower, probably from plants that were in flower this spring.
I could be wrong though
