The Bulltongue arrowhead (Sagittaria lancifolia) belongs to Alismataceae (the Water-plantain family). It is a perennial herb that is native to the southeastern United States. This herb grows in fresh or brackish water, and up to a height of 30-120 cm. It forms large potato-like corms underground. The large, lance-shaped leaves grow up from underground rhizomes. The white flowers bloom at the end of long, thick stalks. Each flower has three green sepals, three white or pink-tinged petals. It reproduces both asexually through spreading rhizomes and sexually through reproduction of copious achenes, a dry fruit each of which carries a single seed.
