Blue Flax - Linum lewisii / Linum perenne ??

I agree with Hywell its a flax plant or linseed or linen depending on what you want to call it by.The fields near us are full of it, its gorgeous.

Thanks from me also, as I have this in my garden and amd forever pulling it up, though I thought mine might have a pink flower does it come in pink and will I regret letting some flower?

It comes in red. I usually sew the seeds. The red one is an annual. I don't get any trouble from it seeding around.

Thanks Hywel
