Title: Another campanulate mystery -- this time teeny, tiny
Post by: Claire Cockcroft on June 13, 2023, 06:19:30 PM: Little white flowers showed up in a planter of other Betty Lowry seed bank plants (Collomia debilis and yet another unknown campanula). The white trumpets are only a centimeter long. Any guesses what this might be?

I think C. lourica has amythest veining between the fused petals.
Claire's flower appears to be pure white.

The pure white blooms and slightly recurved petals suggest C. medium 'Cama White'

I think 'Cama White' has smaller flowers than most C. medium.

the growth habit does not appear to be like Campanula medium which is an upright spike
cheers

Post by: Jon Evans on June 14, 2023, 01:50:24 PM: This is a little annual species which I have grown for years in the alpine house. It used to have a label, but as the plant moves around each year, neither of the plants I have now carry a name, and I have forgotten it. The leaves are distinctive. Try to take seed - dont try to move or repot it, it resents this and dies.

Post by: Claire Cockcroft on June 14, 2023, 05:30:16 PM: Thank you for the advice, Jon. I couldn't dig it if I wanted to -- it's buried in the collomia and the other campanula. I will try to get seeds; time to get the paint brush out to hand pollinate!

C. rotundifolia 'White Gem' looks quite similar.

Post by: Claire Cockcroft on June 15, 2023, 01:23:18 AM: Thanks, Marc, 'White Gem' is much bigger than this little guy.

Post by: Jon Evans on June 15, 2023, 07:21:26 PM: I think it might be Campanula alsinoides - that rings a bell. Some photos show stripes on the fused tube, but mine is pure white.
Title: Re: Another campanulate mystery -- this time teeny, tiny
Post by: Claire Cockcroft on June 16, 2023, 06:25:04 PM: Thanks, Jon. The size and flower match C. alsinoides online pictures. There are very faint stripes on the fused tube that darken slightly as the flower ages. The notation on the seed packet read:
Campanula sp., tiny, white flrs, crevice 3100m
JJH 9186838
ex Gruzia 95-96

And yes, a lot of the seeds in Betty Lowry's seed bank that have germinated and grown on are very, very old. Amazing!
