A couple of Campanulas for ID

[davidbr]

Despite my best efforts online & off, I've drawn a total blank on these two (which probably means they're common as dirt and someone will answer this in two seconds flat...)

Anyway...two alien campanulas, the first a sturdy, white-flowered plant that bears more than a passing resemblance to Cornish Bellflower (C.alliarifolia) but the multiple flower spikes would seem to rule that out. It was growing in rough grassland in the over-flow car park of Weston-super-Mare railway station (photo taken on Jul 21st this year), a fair way from the nearest garden.




The second has standard blue flowers in a cluster, linear foliage and was perhaps a more obvious garden chuck-out, growing as it was in woodland next to an allotment (Royate Hill, in the Bristol suburb of Fishponds). Again, photo taken on July 19th of this year.

All input gratefully appreciated!

The first one could be a white form of Campanula trachelium.

The second is Campanula persicifolia.

2 is Campanula persicifolia

I haven't seen C. alliariifolia, but it could be first photo, but I'm not sure.

Hi

I grow C.alliarifolia, it is in flower at the moment and the flowers are smaller than those in the picture appear to be, also it has ovate almost heart-shaped leaves that not surprisingly looking a lot like Garlic Mustard leaves.

I would go with Tiggrx as a white form of C.trachelium.

All the best
