Poppies?

They are very impressive but to my aesthetic the double headed poppies aren't my thing. I love the species poppies with the open flower heads though.

That's what I have on a small uncultivated area on one of my diagonal beds. They are four feet tall and have wonderful pink single flowers 4 inches in diameter.
I have no Idea where they have come from as there weren't any on the plot last year? I will deffo be trying to get some seeds from them and will take a piccie tomorrow if I think on!

I need to cultivate the bed but will try to work around them until they have set seed.
