Before blooming, the petals are crumpled in the bud, and as blooming finishes, the petals often lie flat before falling away. A whorl of stamens is in the center of the flower.
The pollen of the oriental poppy, Papaver orientale, is dark blue. The pollen of the field poppy or corn poppy (Papaver rhoeas) is dark blue to grey. Bees use poppies as a pollen source.
Type: There are a multitude of poppy varieties in the world, varying in color, size and smell. The colors of the flower petals can range from white, pink, yellow, orange, red and blue. Most poppies have dark (usually black) centers. Perhaps the best known poppy type is the opium poppy, which has been cultivated for centuries for medicinal and recreational uses. The personal cultivation of opium poppy is illegal in the United States and many other countries. There are many types of legal poppy common for gardening purposes. These include the corn poppy, Iceland poppy, Mexican poppy, California poppy and Oriental poppy. These types range in appearance and environmental conditions needed for cultivation.
Uses: All species of poppies are attractive and most are cultivated as ornamental plants. A few species have other uses, principally as sources of drugs and foods. The opium poppy (Papaver somniferum) is so widely used, for both drugs and food, that its worldwide production is monitored by international agencies. It yields opium and opiates, poppy seeds for use in cooking and baking, and poppyseed oil for culinary and other uses, and is also cultivated as an ornamental plant.
