kathrot's Campanula _______ x 1

I love the Campanula flower forms, but am interested in the pinks / reds instead of blues / purples (my garden has too many of them). i thought i’d try this one out – i’m still looking for Campanula punctata ‘Cherry Bells’, in the deep red. in the meantime – does anyone know what this is? it has the potential to become invasive – i weed it every two weeks or so.
