name that plant

It looks very much like Campanula lactiflora Loddon Anna.

I don't have a clue but whatever it is, it's pretty.

What colour are the flowers? Loddon Anna are pale mauve. I am not actually convinced that it is C.lactiflora as the flowers on yours are in spikes, not groups at the top of stems. I do agree that it's a Campanula, though! Could it be C.latifolia???
