Sarracenia purpurea — purple pitcherplant

Facts

The purple pitcherplant is the only pitcherplant native to New England. Carnivory helps it to thrive in the low-nitrogen environment of peat bogs. Insects are attracted into the lurid red or purple pitchers, and are then prevented from getting out by downward-pointing hairs. They eventually fall into the fluid enclosed in the leaves, where the prey are digested by a community of insect larvae, flesh flies, and other organisms. Native Americans used the roots as a diuretic, a treatment for childbirth-related symptoms, and an anti-diabetic (three compounds isolated from S. purpurea show enhanced glucose uptake in rat liver cells). The pitcherplant was also used to prevent smallpox, and recent studies have confirmed that extracts from this plant can inhibit pox viruses from reproducing.
