Etymology The genus comes from the Latin word sagittārius, meaning 'pertaining to arrows', owing to the leaf shape of many species.

Uses Many species have , prized for millennia as a reliable source of starch and carbohydrates, even during the winter. Some are edible raw, though are less bitter when cooked.

Bradford Angier (1974). 9780811706162, Stackpole Books. . ISBN 9780811706162

They can be harvested by hand or by treading the mud in late fall or early spring, causing light to float to the surface. The plants are easy to propagate by replanting the roots.

Native American peoples such as the Algonquian, Omaha people, Pawnee people, and Ho-Chunk use the tubers for food, prepared by boiling or roasting. They were also planted and eaten in China.

In culture

Other names are Pshitola (Dakota), Si" (Omaha-Ponca), Si-poro (Winnebago) and Kirit (Pawnee), 'cricket' (from the likeness of the tuber to the form of a cricket); known also as kits-hat, 'standing in water', the tuber being termed kirit.

Sagittaria is mentioned in the Omaha myths "Ishtinike and the Four Creators" and "How the Big Turtle Went to War".

In 1749, Peter Kalm mentioned Sagittaria as a food plant among the Algonquian peoples:

American explorers Lewis and Clark used arrowhead tubers to survive the winter of 1805–1806.

Katniss Everdeen of the Hunger Games franchise was named after Sagittaria.
