"Poppy is a genus of plants, of which there are numerous species, mostly natives of Europe and Asia, some of them found in the very N. regions, but most of them in the warmer temperate parts. By far the most important species is that known as the opium poppy, also called the white poppy and the oil poppy. But the same species is important on account of the bland fixed oil of the seeds, and is much cultivated as an oil plant. Poppy oil is as sweet as olive oil, and is used for similar purposes. It is imported into the United States in considerable quantities from India. A variety with double flowers is cultivated in flower gardens, under the name of carnation poppy. <em>a,</em> whole plant"&mdash;(Charles Leonard-Stuart, 1911)
