poppies have four petals in white, violet, pink, or red. They surround a star-shaped stigma from which at least five and up to sixteen ’rays’ fan out. A single pistil (containing from 150 to 200 stamens) is surrounded by five concentric circles. Fertilisation produces from 800 to 2,000 seeds. The true opium-producing plant, Papaver somniferum L., is a member of the poppy family Papaveraceae. There are over 100 species in that family, several with many varieties. Most are found in temperate Asia and in central and southern Europe, not in the fields of California.
