Papaver is a genus of poppies, belonging to the Poppy family. The large, showy terminal flowers grow on long, hairy stalks, to a height of even 3 ft or more as in the Oriental Poppy (Papaver orientale). Their color vary from the deepest crimson, lilac, or white, or violet, to bright yellow or soft pink. The tissue-paper-like flowers may be single, double or semi-double.
