What is this pretty thing?

[IHeartDodo]

Hi all, wondering if anyone might know what this plant is?
Hard to see the scale but the flowers are tiny (about 1cm across) and look like tiny paper roses.

looks like a double flower campanula

I think Campanula too. The leaves are a giveaway.

Gorgeous flowers

ooh yes I just googled and that's it!
...off to buy some seeds!
Thank you :)

It's a campanula haylodgensis bali.
I saw it in Holland (really cheap in garden centre) but struggling to find it here.
