Papaver rhoeas

Papaver rhoeas

''Papaver rhoeas'' is an annual herbaceous species of flowering plant in the poppy family, Papaveraceae. This poppy is notable as an agricultural weed and after World War I as a symbol of dead soldiers.

Before the advent of herbicides, ''P. rhoeas'' sometimes was abundant in agricultural fields. Although the corn poppy and the California poppy are widely grown in gardens, only ''Papaver somniferum'', the opium poppy, has significant farm production.

''Papaver rhoeas'' is a variable, erect annual, forming a long-lived soil seed bank that can germinate when the soil is disturbed. In the northern hemisphere it generally flowers in late spring but if the weather is warm enough other flowers frequently appear at the beginning of autumn. It grows up to about 70 cm in height. The stems hold single flowers, which are large and showy, 5–10 cm across,:32 with four petals that are vivid red, most commonly with a black spot at their base. The petals slightly overlap each other. The plant can produce up to 400 flowers in a warm season, despite their lasting only one day. The flower stem is usually covered with coarse hairs that are held at right angles to the surface, helping to distinguish it from ''Papaver dubium'' in which the hairs are more usually appressed . The capsules are hairless, obovoid , less than twice as tall as they are wide, with a stigma at least as wide as the capsule. Like many other species of ''Papaver'', the plant exudes white to yellowish latex when the tissues are broken.:88

Not all corn poppies that are available commercially have red flowers. Selective breeding has resulted in cultivars in yellow, orange, pink, and white. The Shirley poppy is the most known cultivar. A very pale speckled variety, derived from the Shirley, is also available.

A nearly black-flowering hybrid, known as Evelina, was bred in Italy in the late 1990s, with ''P. dubium'', but does not appear to be available commercially.

''P. rhoeas'' is a temperate native with a very wide distribution area, from Africa to temperate and tropical Asia and Europe.

''P. rhoeas'' is a temperate native with a very wide distribution area, from Africa to temperate and tropical Asia and Europe.It grows in fields, beside roads, and on grasslands.
It is hardy to between USDA Zone 8 and Zone 10, or down to 10 °F .

Its origin is not known for certain. As with many such plants, the area of origin is often ascribed by Americans to Europe, and by northern Europeans to southern Europe. It is known to have been associated with agriculture in the Old World since early times and has had an old symbolism and association with agricultural fertility. It has most of the characteristics of a successful weed of agriculture. These include an annual lifecycle that fits into that of most cereals, a tolerance of simple weed control methods, the ability to flower and seed itself before the crop is harvested, and the ability to form a long-lived seed bank. The leaves and latex have an acrid taste and are mildly poisonous to grazing animals.

A sterile hybrid with ''P. dubium'' is known, ''P. x hungaricum'', that is intermediate in all characters with ''P. rhoeas''.

''P. rhoeas'' topped the list in a UK study of meadow pollen production, on a per flower basis, with its rate of 13.3 ± 2.8 μl. The California poppy placed second with a rate of 8.3 ± 1.1 μl. The pollen production of ''P.rhoeas'', on a per flower basis, was very high in comparison with the other plants tested, at almost triple the amount of the top-ranked perennial . When sampled at the level of the entire capitulum, however, it was outranked by the ox-eye daisy, ''Leucanthemum vulgare'', with its 15.9 ± 2 μl measurement. It tied with ''Cosmos bipinnatus''. Neither poppy produced a significant quantity of nectar, making their role in meadow ecology specific to pollen-gathering/consuming insects. As poppies are not wind-pollinated, their pollen poses no allergy risk via inhalation.

The commonly grown garden decorative Shirley poppy is a cultivar of this plant.

The black seeds are edible, and can be eaten either on their own or as an ingredient in bread. Oil made from the seed is highly regarded in France.

The petals contain a red dye which is used in some medicines and wines, also the dried petals are occasionally used to give colour to potpourris.

In traditional folk medicine, it was used for gout, aches, and pains. The petals were used to create a syrup that was fed to children to help them sleep.

Due to the extent of ground disturbance in warfare during World War I, corn poppies bloomed between the trench lines and no man's lands on the Western front. Poppies are a prominent feature of "In Flanders Fields" by Canadian Lieutenant Colonel John McCrae, one of the most frequently quoted English-language poems composed during the First World War. During the 20th century, the wearing of a poppy at and before Remembrance Day each year became an established custom in English-speaking western countries. It is also used at some other dates in some countries, such as at appeals for Anzac Day in Australia and New Zealand.

This poppy appears on a number of postage stamps, coins, banknotes, and national flags, including:

⤷ Two hundred lei
⤷ Canadian twenty-dollar note and Canadian ten-dollar note
⤷ Some commemorative Canadian twenty-five cent coins in 2004 and 2008
⤷ Great Britain commemorative stamps 2000-2009: 2007 Lest we forget - 90th anniversary of the Battle of the Somme

The common or corn poppy was voted the county flower of Essex and Norfolk in 2002 following a poll by the wild plant conservation charity Plantlife.
