Discussion

J. W. Kadereit (1990) suggested that Papaver rhoeas originated on the east coast of the Mediterranean, probably derived from one or more of the other species of the section that are native in that region, and only after (and because) "suitable habitats in sufficient extent were provided by man." Various forms with pale pink or white, unspotted, sometimes doubled petals are grown for ornament, notably the Shirley poppies. In North America, the species escapes from cultivation fairly readily and has been introduced also as a crop weed.

Papaver hybridum should be expected elsewhere in the flora. Some California collections of this crop weed have been misidentified as Papaver apulum Tenore var. micranthum (Boreau) Fedde, which is not known to occur in the flora.
