Can anyone identify this self-seeded flower growing in my pot?

[CosyTurtle]

This beautiful flower has grown by itself in a pot, does anyone know what it is?

Canterbury bells I think.

Looks like a small campanula, roughly speaking an alpibe plant. Pretty and harmless, likes growing in cracks in oavibgcand walls.

Google Lens is quite good at helping identify plants. Try to take pics that show leaves and indicates the height..

It is cantebury bells.
Thank you all.

No idea but I’d love to have it in my garden ☺️

Canterbury Bells is another name for Campanula. These a wide variety, all lovely.

Oh you lucky thing! Of all plants to self-seed, that’s a beautiful one 🌼

It's the perfect time to sow a tray of them as they're biennial. Plant them out in autumn and you could have dozens next year for only a couple of quid!

Aren't they harebells, rather than canterbury bells?

Campanula

They're all campanula species. Difficult to tell quite which from the pic.

Hold on, can you really use seeds, just put them in the ground and they grow?
Campanulas are one of my favourite flowers. I love all sizes and I’ve been spending a lot of money buying them in pots to plant in the ground.
The ground covering ones don’t always take for some reason.

Yes you can grow them from seed, there are lots of varieties, some quite different sizes and style.
Usually sown in a greenhouse or indoors from Autumn to Spring, they then can be planted outside after the last frost has gone. But different varieties require different germination conditions. It can take some quite a long time to get established, which is why the larger types are better bought as plants.
Its fun growing from seed, so a bit of research and reading the back of the seed packet should help you.

I have that. Originally they were all blue but now I have white ones too.
