What vegetables/fruits benefit from having cornflowers around?

[Snailfox]

I've got some cornflower seed that I'll be planting come spring, down at the allotment, but was wondering if anyone has any idea what sort of vegetables (if any) benefit from their presence? I've read that they're good for the bees, but other than that, I don't know much about them.

I'm sure I've read something about cornflowers being good to plant amongst carrots but anyway I know bees love them so that's why I grow them in my garden.
