Sagittaria platyphylla, the delta arrowhead, [2] broad-leaf arrowhead or delta duck-potato, is a plant species native to the eastern United States. The core of its range extends from central Texas to the Florida Panhandle north to southern Illinois.
As an ornamental it has also been spread to other locations. [3] Isolated populations have been reported from Washington state, Missouri, Kansas, Ohio, Kentucky, Pennsylvania, West Virginia, eastern Virginia, North and South Carolina and eastern Georgia, Nuevo León, Michoacán and Panamá. It has also become a noxious weed in Australia. [4] On August 6 2015 S. platyphylla was found for the first time in China, specifically in the Yangtze River Basin. This detection was in an irrigation ditch in Zhangjiashai, Wuhan, Hubei, PRC. Other detections have continued through at least 2019 demonstrating its establishment in provinces of the middle and lower Yangtze. It presents a significant threat to the ecology and economy of the Yangtze area, especially to agricultural irrigation. [3]
The plant is an emergent aquatic found in ponds, lakes and slow-moving streams. [5] [6] [7] Sagittaria platyphylla is a perennial herb up to 150 centimetres (59 in) tall, producing underground corms (similar to tubers). The plant reproduces by means of stolons as well as seeds. Some leaves are totally submerged, others emergent (raising above the surface of the water). Submerged leaves have flattened petioles but no true blades. Emergent leaves have ovate to elliptical blades up to 17 centimetres (7 in) long. Inflorescence is a raceme with 3-9 whorls of flowers. Flowers are white, up to 2 centimetres (3⁄4 in) in diameter.

Sagittaria is a genus of about 30 species of aquatic plants whose members go by a variety of common names, including arrowhead, duck potato, katniss, Omodaka, swamp potato, tule potato, and wapato. Most are native to South, Central, and North America, but there are also some from Europe, Africa, and Asia.
Sagittaria latifolia is a plant found in shallow wetlands and is sometimes known as broadleaf arrowhead, duck-potato, Indian potato, or wapato. This plant produces edible tubers that have traditionally been extensively used by the indigenous peoples of the Americas.
Sagittaria montevidensis is a species of flowering plant in the water-plantain family Alismataceae. Common names include giant arrowhead and California arrowhead.
Sagittaria lancifolia, the bulltongue arrowhead, is a perennial, monocot plant in the family Alismataceae, genus Sagittaria, with herbaceous growth patterns. It is native to the southeastern United States. It is known from every coastal state from Delaware to Texas. The species is also considered native to Mexico, Central America, the West Indies and northern South America. It has become naturalized on the Island of Java in Indonesia.
Sagittaria cuneata is a species of flowering plant in the water plantain family known by the common name arumleaf arrowhead or duck potato. Like some other Sagittaria species, it may be called wapato. It is native to much of North America, including most of Canada as well as the western and northeastern United States.
Sagittaria longiloba is a species of flowering plant in the water plantain family known by the common name longbarb arrowhead and Gregg arrowhead. It is native to the south-central and southwestern United States plus Mexico, Venezuela and Nicaragua. It is also reportedly naturalized in the western Himalayas of India and Bhutan. It grows in slow-moving, stagnant, and ephemeral water bodies such as ponds and small streams, and sometimes disturbed and cultivated habitat such as rice fields and irrigation ditches.
Sagittaria sanfordii is an uncommon species of flowering plant in the water plantain family known by the common names valley arrowhead and Sanford's arrowhead. It is endemic to California, where it is known from a few scattered occurrences on the North Coast and in the Central Valley. Many occurrences previously noted in the Central Valley and in southern California have been extirpated as the plant's aquatic habitat has been lost to human activity.
Sagittaria australis, the Appalachian arrowhead or longbeak arrowhead, is a plant species native to much of the eastern part of the United States, from Louisiana to Iowa to New York State to Florida, mostly between New Jersey and Mississippi with scattered locations elsewhere in the range.

Sagittaria rigida, the sessilefruit arrowhead or Canadian arrowhead, is an aquatic plant species native to Canada and to the United States and also naturalized in Great Britain. It grows in shallow waters along the edges of ponds and streams. It generally has linear to narrowly elliptical leaves and sessile female flowers.
Sagittaria kurziana, common names springtape and strap-leaf sagittaria, is an aquatic plant species native to Florida and naturalized in the Mariana Islands. It grows along large springs, very often those with high sulfur content, and along the banks of watercourses downstream from such springs.
