Lance-leaf Arrowhead, (Sagittaria lancifolia), is commonly found in freshwater marshes and swamps and along streams, ponds, and lakes. It tolerates brackish water. This native Florida plant, also known as Duck Potato, can grow to 4-feet tall. The plant is a rhizomatous perennial that also reproduces with seed dispersal. It thrives in water up to 12-inches deep and in silty, wet soils.
Birds enjoy the seeds and tubers and use the plants for cover. Other aquatic animals such as fish and insects find shelter in the foliage. Lance-leaf Arrowhead extracts metals and nutrients from water and sediments where it grows. Native Americans used the corms which are bulb-like stem parts as food, to treat wounds, and as herbal medicine to treat a variety of ailments.
