Broadleaf Arrowhead   Sagittaria latifolia

This semi-submerged succulent – commonly known as duck potato and Indian onion -- has arrowhead leaves that grow up to three feet tall, and produces white flowers in summer. Its small nutlet seeds and tuberous egg-shaped roots are favorite foods of waterfowl and muskrats. It is best planted in full sun in the spring in mud or water as deep as two feet. The plant serves as a good water filter and oxidizer if it can be protected from grazing animals.

The Shinnecock Indians harvested many parts of this plant -- for food, for fiber for mats and baskets, and for calking and other home uses.
