Discussion | Subspecies numerous (4 in the flora). Many infraspecific taxa have been named from throughout the extensive range of this extremely variable species. Within North America, the following broadly circumscribed subspecies are generally, but not always, distinguishable. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Unknown in the wild, Papaver somniferum probably came originally from southeastern Europe and/or southwestern Asia. It has been cultivated for centuries as the source of opium (and its modern derivatives heroin, morphine, and codeine), and also for edible seeds and oil. Various color forms with laciniate and/or doubled petals are grown for ornament. Widely introduced from cultivation and also as a crop weed, it should be expected elsewhere in the flora.
