Arrowhead, duck potato or wapato is a vigorous, deciduous, marginal aquatic perennial that typically grows 1-4′ tall. It is noted for its arrowhead-shaped leaves and three-petaled white flowers in whorls of three. Fantastic Arrowhead features variegated foliage. It commonly grows submerged in shallow water or out of water on wet muddy banks. It is native to sloughs, swamps, marshes and margins of streams and ponds throughout North America. Plants bloom freely from July to September. The common names of duck potato and wapato are in reference to the enlarged rounded starchy golfball-sized tubers that form at the ends of underground plant runners (rhizomes).
