Unknown Campanula or Symphyandra

[Knud]

Hello,
I have this biennial plant self-seeding carefully in the rockgarden. First year it has a small rosette of leaves, less than 2-5 cm (1-2") across, as seen immediately below the flower in the bottom left corner of the attached picture. In the second year the rosette grows in size, like on the right edge of the picture, and it sends out a long, 10 - 20 cm (4 - 8") creeping stem along which blooms several upturned white ( or very pale blue) bells. Two are blooming, and several buds can be seen in the picture.

I called it unknown Campanula in the picture, but I now wonder if it might be a Symphyandra.

Any suggestions?

Thanks,
Knud

Possibly C. sartori - or possibly not. It should be greyer in the leaf.

Thank you again Lesley,
from what I can find about C. Sartorii on the internet it looks like the one I have. And it is usually greyer in leaf, but this summer's incessant rain has wet it properly and made it appear greener than normal.

Knud we had this once but it disappeared from the garden, a year later it popped up right next to a drain so it obviously doesn't mind water.

All Symphyandras have now gone back into Campanula

Oh my, thanks for that Diane.... this shifting about drives me nuts...

I think you are right about the water Shelagh, we have had a very wet summer thus far and the plants of this campanula have never been as big as this year.

Thank you Diane, for this information. When the genus name changes, do they keep the species name? So are the S. zangezura and S. hoffmannii we have now Campanula zangezura and C. hoffmannii?

Yes, because Symphyandra and Campanula are the same gender, then the species name is the same, so we have C zangezura and C hofmannii (one "f")

Thank you Diane, for the useful link. The C. zangezura and hofmannii selfsow here and there in the garden, the hofmannii more than the zangezura. The C. hofmannii in the picture below appeared in a pot next to my old Yucca harrimaniae.
