well some people would say its a weed, but it looks a bit like forget me nots

Weed, devil to get out as well, roots go down to Australia... can't remember what its called either.

Borage?

is it borage or is it alkanet

forgot to add hellcat,if its borage the leaves can be eaten in a salad and taste like cucumber or infused and made into a drink

It's not borage, the flowers are larger, darker and more "clustery" and the buds are hairy.I'll go for alkanet too. Loves damp ditches, good for a "natural garden".
How's this for a match?

Thanks for the replies. Definitely alkanet, so will have to decide what to do about it!!! Looks quite pretty but spreading out of control. Watch this space

I have alkanet in a wild part of the garden. the bees like it. it is a member of the borage family too.

My guess, Hellcat: viper's bugloss (Echium vulgare), probably in more shade than it likes

definately not Borage , the leaves would be furry as well , if it was borage the flowers would be star like

Well, whatever it's called (can't be bothered to check, no time) the leaves on this are unpleasant to touch, very rough.
