When is the best time to divide campanula? I have very "busy" rosettes from last year .... I forgot to take a picture of them at their best last year, so I've uploaded one that shows them nearly past flowering (as I can't remember what kind I bought) but anyway, in the photo they're sandwiched between the jap anemones and osteospermums .... help!

Now is a good time to split any perennials, as long as the soil isn't frozen. I can't tell from your photo which Campanulas they are, I'm afraid, so I can't say if they're 'splittable' plants. Try one and see if you can. :-)
