Broadleaf Arrowhead (Duck Potato) Sagittaria latifolia is an emergent, colony-forming, aquatic perennial plant (24” – 36“) with fleshy, arrow-shaped basal leaves. It occurs throughout Louisiana in marshes, ponds, streams, swamps and ditches. White or pink-tinged blooms appear on a flower stalk located between the leaves July – November.
Rhizomes form starchy tubers known as “duck potatoes”, which are eaten by at least 15 species of ducks, snapping turtles, and muskrats. Broadleaf Arrowhead thrives in mud, shallow water or fully saturated soils in sun to part shade. It makes an attractive plant in a water garden, bog, or pond.
