Real identity of "Campanula rigidipila" of gardens?

What's the correct name for the (quite nice) plant making its rounds as "Campanula rigidipila"? The real C. rigidipila is an Ethiopian native, and looks nothing like the plant I grow in my garden.

Campanula sarmatica or a closely related taxon. Occurs in Caucasus.

Thank you, that looks like a perfect match! I see that C. sarmentosa and C. rigidipila are synonyms, so the mix-up with C. sarmatica does make some sense.
