Title: Campanula thyrsoides - set no seeds
Post by: Catwheazle on August 25, 2025, 07:36:50 AM

Hello, I've had both varieties of Campanula thyrsoides in cultivation and flowering several times. Unfortunately, they never set seeds for me, so I don't have any plants left at the moment. I want to try again this fall. Does anyone have any help?
Thanks!
Bernd

Bernd,

They frequently appear on the exchanges.
Between the SRGC and AGS exchanges you are very likely to find it.

Hello,
that's not the problem. I received seeds and young plants. My question is: Does anyone have any idea why my plants aren't producing seeds?

Bernd,

I have read about a shortage of pollenators in Europe. Perhaps your plants are not being visited. You might consider buying some bees.

I'd also thought that a special pollinator might be present. Although: there are (still) quite a few wild bees and bumblebees in my garden. ...What could also speak for a special pollinator is the fact that they don't occur here in the mountains. 50-100 km away, in Austria, with the same soil and the same altitude, they exist again.
