American Mannagrass is a tall, robust native grass of wet habitats across most of North America, growing 3–5 feet tall in marshes, stream banks, and shallow water. It produces large, spreading, purplish-green panicles that arch gracefully in summer. Mannagrass seeds were an important food for Indigenous peoples of the Great Lakes region, where they were harvested by canoe in a process similar to wild rice harvesting. It provides excellent waterfowl habitat.
