Papaver setigerum, common name poppy of Troy or dwarf breadseed poppy, is a herbaceous annual plant of the family Papaveraceae.
This plant is closely related to and sometimes treated as a subspecies of opium poppy (Papaver somniferum). In fact it produces a very small amount of morphine alkaloids. However, P. somniferum is diploid (n=11) and P. setigerum is tetraploid (n=22) with twice the number of chromosomes. So it cannot be considered the wild ancestral species of the opium poppy.
