Papaver dubium is a species ofpoppy known by the common nameslong-headed poppy andblindeyes. It is an annual species which prefers sandy soils without lime. It is native to Europe, North Africa and south-western Asia and widespread as an introduction in America and elsewhere.[1][2]
Papaver dubium is a variable annual, growing to about 60 cm in height. It generally flowers in late spring to mid-summer. The flower is large (30–70 mm)[3] and showy, with four petals that are lighter red than in the similarPapaver rhoeas, and most commonly without a black spot at the base. Theflower stem is usually covered with coarse hairs that are closely appressed to the surface, helping to distinguish it fromP. rhoeas in which the hairs are more usually patent, held at right angles to the stem. The capsules are hairless, elongated to more than twice as tall as they are wide, tapering slightly at the tip, with a stigma generally less wide than the capsule. The plant exudes white to yellowishlatex when the tissues are broken.[4] The species can form a long-livedsoil seed bank that can germinate when the soil is disturbed.
A nearly black-flowering hybrid, known as Evelina, was bred in Italy in the late 1990s, withPapaver rhoeas, but does not appear to be available commercially.[5]
