Sarracenia is a genus comprising 8 to 11 species of North American pitcher plants, commonly called trumpet pitchers. The genus belongs to the family Sarraceniaceae, which also contain the closely allied genera Darlingtonia and Heliamphora. Sarracenia is a genus of carnivorous plants indigenous to the eastern seaboard, Texas, the Great Lakes area and southeastern Canada, with most species occurring only in the south-east United States (only S. purpurea occurs in cold-temperate regions). The plant's leaves have evolved into a funnel in order to trap insects, digesting their prey with proteases and other enzymes. The insects are attracted by a nectar-like secretion on the lip of pitchers, as well as a combination of color and scent. Slippery footing at the pitchers' rim, aided in at least one species by a narcotic drug lacing the nectar, causes insects to fall inside, where they die and are digested by the plant as a nutrient source.
