Field Poppy

I have two species of Poppy in the garden, this one which I believe to be the Field  Poppy or Corn Poppy and the Long Headed Poppy.   This one has four black marks at the base of the petals which look similar to a Celtic Cross.   I know puritans will say I shouldn't have Poppies in the garden, but I love them and against the deep indigo Aquilegias they look stunning.
