Sagittaria lancifolia L.
Lanceleaf Arrowhead, Duck-potato, Bulltongue Arrowhead
Alismataceae (Water-Plantain Family)
USDA Symbol: SALA
This perennial arises with basal leaves to 3 feet tall from tuber-producing rhizomes. The leaves have long petioles and arrowhead shaped leaf blades to 10 inches long. Submerged leaves are lance-shaped or even bladeless. The ½ to 1 inch wide 3 petaled white flowers appear in late spring and summer.
Members of the Water-Plantain Family grow in water, in swamps, on muddy banks, or occasionally in wet sand. Each plant has long-petioled leaves in a clump with a flowering stem rising among them. The flowers have 3 green sepals, 3 white or pink-tinged petals, 6 or more stamens, and several pistils. Stamens and pistils may be in separate flowers.

Native Habitat: This is the most common arrowhead of eastern North America. It grows at low elevations in shallow water on the fringe of ponds, lakes, streams and wet ditches.
Growing ConditionsWater Use: High
Light Requirement: Sun
Soil Moisture: Wet
Conditions Comments: Arrowheads are reliable perennials used for water gardens. In nature, they are emergent aquatic plants that grow on the margins of ponds and slow moving streams. They should be planted no deeper that 12 in a water garden in a full sun location.
BenefitUse Food: Called Duck Potato or Wapato because of its edible egg-shaped rhizomes. Native Americans cleared ponds of competing plants to locate and harvest the tubers in fall. The tubers were stored and cooked as needed, providing an excellent source of carbohydrates.
