Papaver somniferum
Summary
Papaver somniferum, commonly known as the opium poppy or breadseed poppy, is a species of flowering plant in the family Papaveraceae. It is the species of plant from which both opium and poppy seeds are derived and is also a valuable ornamental plant grown in gardens. Its native range was east of the Mediterranean Sea, but now is obscured by ancient introductions and cultivation, being naturalized across much of Europe and Asia.
This poppy is grown as an agricultural crop on a large scale, for one of three primary purposes. The first is to produce seeds that are eaten by humans, commonly known as poppy seed. The second is to produce opium for use mainly by the pharmaceutical industry. The third is to produce other alkaloids, mainly thebaine and oripavine, that are processed by pharmaceutical companies into drugs such as hydrocodone and oxycodone. Each of these goals has special breeds that are targeted at one of these businesses, and breeding efforts (including biotechnological ones) are continually underway. A comparatively small amount of P. somniferum is also produced commercially for ornamental purposes.
The common name "opium poppy" is increasingly a misnomer as many varieties have been bred that do not produce a significant quantity of opium. The cultivar 'Sujata' produces no latex at all. Breadseed poppy is more accurate as a common name today because all varieties of P. somniferum produce edible seeds. This differentiation has strong implications for legal policy surrounding the growing of this plant.
Papaver somniferum is an annual herb growing to about tall. The plant is strongly glaucous, giving a greyish-green appearance, and the stem and leaves bear a sparse distribution of coarse hairs. The large leaves are lobed, the upper stem leaves clasping the stem, the lowest leaves with a short petiole. The flowers are up to diameter, normally with four white, mauve or red petals, sometimes with dark markings at the base. The fruit is a hairless, rounded capsule topped with 12–18 radiating stigmatic rays, or fluted cap.
