Purple Pitcher Plant, Sarracenia purpurea

Quoddy Head State Park
Pitcher plants are carnivorous. Their leaves fuse together to form a pitcher-shaped container that fills with water. The lips of the pitcher are lined with downward-pointing hairs. Any insects that land in the pitcher for a drink are unable to climb out, and eventually drown and sink to the bottom. There they are digested. Pitcher plants (and other carnivorous plants) do not kill insects for energy (they are able to photosynthesize), but to obtain nitrogen, which is scarce in the boggy soils in which they grow.
