Sarracenia (/ˌsærəˈsiːniə/ or /ˌsærəˈsɛniə/) 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. The plant attracts its insect prey with secretions from extrafloral nectaries on the lip of the pitcher leaves, as well as a combination of the leaves' color and scent. Slippery footing at the pitcher's rim, causes insects to fall inside, where they die and are digested by the plant with proteases and other enzymes.
