Can anyone tell me what this plant is?

I am so not green-fingered, but this is going nuts in my garden this year and the bees absolutely adore it! It's beautiful whatever it is

it's a bellflower... campanula latifolia

Thank you gatekeeper!

Lovely isn't it; I have different varieties of campanula dotted about and between them and the foxgloves all I can hear all day is muffled buzzing
