The Corn Poppy, Field Poppy, Flanders Poppy, or Red Poppy is the wild poppy of agricultural cultivation-Papaver rhoeas. It is a variable annual plant. The four petals are vivid red, most commonly with a black spot at their base. 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 has a variety of common names. 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. Like many such weeds, it also shows the tendency to become a crop in its own right; its seed is a moderately useful commodity, and its flower is edible.
