The flowers of most poppy species are attractive and are widely cultivated as annual or perennial ornamental plants. This has resulted in a number of commercially important cultivars, such as the Shirley poppy, a cultivar of Papaver rhoeas and semi-double or double (flore plena) forms of the opium poppy Papaver somniferum and oriental poppy (Papaver orientale). Poppies of several other genera are also cultivated in gardens. A few species have other uses, principally as sources of drugs and foods. The opium poppy is widely cultivated and its worldwide production is monitored by international agencies. It is used for production of dried latex and opium, the principal precursor of narcotic and analgesic opiates such as morphine, heroin and codeine. Poppy seeds are rich in oil, carbohydrates, calcium and protein. Poppy oil is often used as cooking oil, salad dressing oil, or in products such as margarine. Poppy oil can also be added to spices for cakes, or breads. Poppy products are also used in different paints, varnishes, and some cosmetics (Jonsson and Krzymanski, 1989).
