This has popped up in my garden and it's so pretty, but I have no idea what it is! Can anyone help?

hmm big photo fail - I will try again.....

third time lucky- bloody mobile!

Might be a campanula?

It is a campanula, they come in several varieties. This one is my favourite, it also comes in blue. They will self seed around the garden.

Yep, campanula or Canterbury bells. I love them!

Thanks you all, it really is lovely and I'm delighted that they will self seed around the garden!
