Mystery campanula

[fermi de Sousa]

I received this as seed from the ?AGS Seedex a few years ago as "Campanula ?aff. lourica".
It flowered last year and this is the second generation.
The foliage looks more like a silene and they were nearly binned because I feared they were S.flavescens, a particularly pernicious weed in this garden!
The original plant is still alive and flowering so it doesn't appear to be monocarpic, but flowering this heavily from seed in less than 12 months make me worry it has weed potential!
Any ideas on what it might be?
cheers

OOPs, no, sorry, i was mistaking it for YOUR Campanula ? trogerae and Lesley's hybrid. I could have sworn I saw a furry leaved campanula like this somewhere lately... perhaps I need to have some supper, i may be hallucinating! Just realised I haven't had eaten... most unlike me!
