The plant is a variable 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. The flower is large and showy, with four petals that are vivid red, most commonly with a black spot at their base. Like many other species of ''[[Papaver]]'', it exudes a white [[latex]] when the tissues are broken.
It is known to have been associated with [[agriculture]] in the [[Old World]] since early times. 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.

Papaver Rhoeas, Linn. Corn Poppy. Fig. 2750. Hispid annual, or rarely glabrescent. erect and branching, 1 to about 3 ft.: lvs. coarselv toothed (rarely nearly entire) to more or less pinnatifid, lanceolate in outline: bud oblong- ovoid, roundish at apex: petals orbicular or nearly so, entire or sometimes crenate or incised, cinnabar-red, deep purple to scarlet, white and variously marginate, sometimes dark-spotted, the fls. 2 in. or more across; stigmatic disk usually 10-radiate, but varying from 5-18. Eu. and Asia; run wild in N. Amer. Abundant in fields in Eu. Gn. 30, p. 297.—An immensely variable species,from 25-30 botanical varieties and subvarieties being recognized; and the cultural variations are numberless. In cult, every shade known to the opium poppy has been reproduced in the corn poppy, but the fls. are always smaller. In the wild it varies greatly, the foliage once or twice pinnately parted, the bristles many or few, appressed or spreading, the fls. spotted or not. Up to 1886 the French poppies were considered the best strain. Since then the strain or race known as Shirley poppies has surpassed all others. This strain was developed by the Rev. W. Wilks, secretary of the Royal Horticultural Society. (See p. 2456.) Var. ranunculi- florum, Hort., is a strain with double fls. in various colors, self and variegated, with the petals entire, rounded and somewhat reflexed. Var. japonicum, Hort., is a strain intro. about 1893 from Japanese gardens, and said to have smaller and fuller fls. than ordinary and of more varied shades. They are called Japanese or Japanese pompons. Rhaeas was the name used by the ancient Greeks and Romans for the corn poppy.
