The plant Papaver Somniferum aka the Opium Poppy.
Opium poppy, Papaver somniferum, is the species of plant from which opium and poppy seeds are extracted.
Opium is the source of many opiates, including morphine, thebaine, codeine, papaverine, and noscapine.
The Latin botanical name means the “sleep-bringing poppy”, referring to the sedative properties of some of these opiates.
The poppy is the only species of Papaveraceae that is an agricultural crop grown on a large scale.
Other species, Papaver rhoeas and Papaver argemone, are important agricultural weeds, and may be mistaken for the crop.
