Hi,
I grew this from seed and have it labelled as
Campanula autraniana; however, the leaf shape (among other things, I imagine) is wrong for that (supposed to be "cordate-acuminate, finely dentate on long petioles" according to Graham Nicholls'
Dwarf Campanulas).
I think it's
C. tridentata... or at least in that bunch of similar ones, i.e.
C. tridentata/aucheri/saxifraga/bellidifolia. Having said that, the flowers are larger and tubbier than what I grow as
C. saxifraga.
Can anyone say what it is? Thanks for any info.
