Opium poppies are popular and attractive garden plants, whose flowers vary greatly in color, size and form. A modest amount of domestic cultivation in private gardens is not usually subject to legal controls. In part, this tolerance reflects variation in addictive potency. A cultivar for opium production, "Papaver somniferum L. elite", contains 91.2 percent morphine, codeine, and thebaine in its latex alkaloids, whereas in the latex of the condiment cultivar "Marianne", these three alkaloids total only 14.0 percent. The remaining alkaloids in the latter cultivar are primarily narcotoline and noscapine.
