Below is the notorious Papaver somniferum or opium poppy, growing in Giverny, France. Most people probably know that this plant is responsible for the drugs morphine, codeine and of course, heroin.
Poppies were first recorded as a cultivated plant by Sumerians around 4000BC. They called it the 'plant of joy' presumably due to the narcotic effects the plant had on them.
The seed pods themselves are quite sculptural in the garden but no, you probably won't be able to do much with this plant in its rare form. (Not that you'd try.) The process of converting the milky sap of the fruit into a drug is fairly complicated, as I recently learned in an article on PBS Frontline. But you can enjoy the lovely flower of this annual, self-seeding plant. You can also enjoy poppyseed muffins, but remember what happened to Elaine on Seinfeld.
There are over 100 species of Papaver. Though I cannot find out why this plant was given the genus name Papaver, somniferum refers to the sleep-inducing qualities of this plant.
