Sagittaria lancifolia (Bulltongue Arrowhead or Duck Potato) is a bold, tuber-producing aquatic perennial native to Texas and the southeastern U.S. Known for its tall, arrowhead-shaped leaves and clean white flowers, it thrives in shallow water at the edges of ponds, ditches, and slow-moving streams. Often called "Duck Potato" or "Wapato," this plant produces edible rhizomes historically harvested by Native American communities. It's perfect for pond margins and bog filters, providing both ecological and cultural value.
