Also known as Duck Potato or Wapato, Arrowhead produces edible tubers. Grow arrowhead in water gardens, pond edges, or decorative containers with 3 to 6 inches of standing water.The showy white flowers are often hidden in the large arrow-shaped foliage. The edible tubers are a food source for ducks and will float to the water surface once dislodged from the muck. The "potatoes" will form new plants if given the chance; arrowhead spreads vigorously.Uses: birds, edible, pond/wetland restoration, container gardeningBloom time: June - SeptemberHeight: 18 to 30 inchesSpace: 2 to 5 feetSun: Half to full sunMoisture: Submerged, wet
