Poppies. A poppy is a flowering plant in the subfamily Papaveroideae of the family Papaveraceae. Poppies are herbaceous plants, often grown for their colourful flowers. One species of poppy, Papaver somniferum, is the source of the narcotic drug opium which contains powerful medicinal alkaloids such as morphine and has been used since ancient times as an analgesic and narcotic medicinal and recreational drug. It also produces edible seeds. Following the trench warfare in the poppy fields of Flanders, Belgium during World War I, poppies have become a symbol of remembrance of soldiers who have died during wartime. Poppies are herbaceous annual, biennial or short-lived perennial plants. Some species are monocarpic, dying after flowering. Poppies can be over a metre tall with flowers up to 15 centimetres across. Flowers of species have 4 to 6 petals, many stamens forming a conspicuous whorl in the center of the flower and an ovary of from 2 to many fused carpels. The petals are showy, may be of almost any color and some have markings. The petals are crumpled in the bud and as blooming finishes, the petals often lie flat before falling away. In the temperate zones, poppies bloom from spring into early summer. Most species secrete latex when injured. Bees use poppies as a pollen source. The pollen of the oriental poppy, Papaver orientale, is dark blue, that of the field or corn poppy is grey to dark green. The opium poppy, Papaver somniferum, grows wild in eastern and southern Asia, and South Eastern Europe. It is believed that it originated in the Mediterranean region. Poppies belong to the subfamily Papaveroideae of the family Papaveraceae, which includes the following genera: Papaver-Papaver rhoeas, Papaver somniferum, Papaver orientale, Papaver nudicaule, Papaver cambricum. Eschscholzia-Eschscholzia californica. Meconopsis-Meconopsis napaulensis. Glaucium-the horned poppies including Glaucium flavum and Glaucium corniculatum. Stylophorum-celandine poppy. Argemone-prickly poppy. Romneya-matilija poppy and relatives. Canbya-pygmy poppy. Stylomecon-wind poppy. Arctomecon-desert bearpaw poppy. Hunnemannia-tulip poppy. Dendromecon-tree poppy. 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 forms of the opium poppy Papaver somniferum and oriental poppy. 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. Ancient Egyptian doctors would have their patients eat seeds from a poppy to relieve pain. Poppy seeds contain small quantities of both morphine and codeine, which are pain-relieving drugs that are still used today. Poppy seeds and fixed oils can also be nonnarcotic because when they are harvested about twenty days after the flower has opened, the morphine is no longer present. In Mexico, Grupo Modelo, the makers of Corona beer, used red poppy flowers in most of its advertising images until the 1960s. Artificial poppies are used in the veterans' aid campaign by the Veterans of Foreign Wars, which provides money to the veterans who assemble the poppies and various aid programs to veterans and their families. A poppy flower is depicted on the reverse of the Macedonian 500-denar banknote, issued in 1996 and 2003. The poppy is also part of the coat of arms of North Macedonia. Canada issued special quarters with a red poppy on the reverse in 2004, 2008 and 2010. The 2004 Canadian poppy quarter was the world's first coloured circulation coin. The girl's given name Poppy is taken from the name of the flower. Poppies have long been used as a symbol of sleep, peace, and death: Sleep because the opium extracted from them is a sedative, and death because of the common blood-red color of the red poppy in particular. In Greek and Roman myths, poppies were used as offerings to the dead.
