Papaver dubium is a species of poppy known by the common names Long-headed Poppy and Blindeyes. It is a very undemanding species which prefers sandy soils without lime. It is widespread throughout Europe and America. It has been introduced into Australia, probably accidentally, but at least around Melbourne it is not widespread.
