Papaver rhoeas - the corn poppy, red poppy or corn poppy - is an annual herbaceous species in the poppy family, Papaveraceae, notable as an agricultural weed. It is an erect annual growing up to about 70 cm in height, with stems holding single large and showy, 5 to 10cm across flowers with four petals that are usually vivid red, most commonly with a black spot at their base. Not all poppies that are available commercially have red flowers. Selective breeding has resulted in cultivars in yellow, orange, pink, and white, with the Shirley Poppy probably being the most known cultivar.
