Opium poppy

Papaver somniferum, commonly called the opium poppy, is a plant used for manufacturing opium, the base of many narcotics including morphine, thebaine, codeine, and others. Opium is also the requisite resource for the manufacture of heroin, though thankfully, opium poppies are impossible to cultivate in northern America due to the extreme change in climate. Myron and the Mordinos learned this the hard way.
