Wild rice
Wild rice, also called manoomin, mnomen, psíŋ, Canada rice, Indian rice, or water oats, is any of four species of grasses that form the genus Zizania, and the grain that can be harvested from them. The grain was historically and is still gathered and eaten in North America and, to a lesser extent, China, where the plant's stem is used as a vegetable.
Wild rice and domesticated rice, are in the same botanical tribe Oryzeae. Wild-rice grains have a chewy outer sheath with a tender inner grain that has a slightly vegetal taste.
The plants grow in shallow water in small lakes and slow-flowing streams; often, only the flowering head of wild rice rises above the water. The grain is eaten by dabbling ducks and other aquatic wildlife.
Species
Three species of wild rice are native to North America:- Northern wild rice is an annual plant native to the Great Lakes region of North America, the aquatic areas of the Boreal Forest regions of Northern Ontario, Alberta, Saskatchewan and Manitoba in Canada and Minnesota, Wisconsin, Michigan and Idaho in the US.
- Southern or annual wild rice, also an annual, grows in the Saint Lawrence River, the state of Florida, and on the Atlantic and Gulf coasts of the United States.
- Texas wild rice is a perennial plant found only in a small area along the San Marcos River in central Texas.
- Manchurian wild rice is a perennial native to China.
The genomes of northern and Manchurian wild rices have been sequenced. There appears to be a whole-genome duplication after the genus split from Oryza.
Culinary use
The species most commonly harvested as grain are the annual species: Zizania palustris and Zizania aquatica. The former, though now domesticated and grown commercially, is still often gathered from lakes in the traditional manner, especially by indigenous peoples in North America; the latter was also used extensively in the past. The stems and root shoots also contain an edible portion on the interior.Use by Native Americans
and others harvest wild rice by canoeing into a stand of plants, and bending the ripe grain heads with two small wooden poles/sticks called "knockers" or "flails", so as to thresh the seeds into the canoe.One person vans rice into the canoe while the other paddles slowly or uses a push pole. The plants are not beaten with the knockers, but require only a gentle brushing to dislodge the mature grain. Some seeds fall to the muddy bottom and germinate later in the year. The size of the knockers, as well as other details, are prescribed in state and tribal law. By Minnesota statute, knockers must be at most diameter, long, and weight.
Several Native American cultures, such as the Ojibwe, consider wild rice to be a sacred component of their culture. The Ojibwe people call this plant ᒪᓅᒥᓐ manoomin, meaning . In 2018, the White Earth Nation of Ojibwe granted manoomin certain rights, including the right to exist and flourish; in August 2021, the Ojibwe filed a lawsuit on behalf of wild rice to stop the Enbridge Line 3 oil sands pipeline, which puts the plant's habitat at risk.
Tribes that are recorded as historically harvesting Zizania aquatica are the Dakota, Menominee, Meskwaki, Ojibwe, Cree, Omaha, Ponca, Thompson, and Ho-Chunk. Native people who utilized Zizania palustris are the Ojibwe, Ottawa/Odawa and Potawatomi. Ways of preparing it varied from stewing the grains with venison stock and/or maple syrup, making it into stuffings for wild birds, or even steaming it into sweets like puffed rice, or rice pudding sweetened with maple syrup. For these groups, the harvest of wild rice is an important cultural event. The Omǣqnomenēwak tribe take their name, and the name Omanoominii that the neighboring Ojibwa use for them, from this plant. Many places in Illinois, Indiana, Manitoba, Michigan, Minnesota, Ontario, Saskatchewan, and Wisconsin are named after this plant, including Mahnomen, Minnesota, and Menomonie, Wisconsin; many lakes and streams bear the name "Rice", "Wildrice", "Wild Rice", or "Zizania".
Commercialisation
Because of its nutritional value and taste, wild rice increased in popularity in the late 20th century, and commercial cultivation began in the U.S. and Canada to supply the increased demand. In 1950, James and Gerald Godward started experimenting with wild rice in a one-acre meadow north of Brainerd, Minnesota. They constructed dikes around the acre, dug ditches for drainage, and put in water controls. In the fall, they tilled the soil. Then, in the spring of 1951, they acquired of seed from Wildlife Nurseries Inc. They scattered the seed onto the soil, diked it in, and flooded the paddy. Much to their surprise, since they were told wild rice needs flowing water to grow well, the seeds sprouted and produced a crop. They continued to experiment with wild rice throughout the early 1950s and were the first to officially cultivate the previously wild crop.In the United States, the main producers are California and Minnesota, and it is mainly cultivated in paddy fields. In Canada, it is usually harvested from natural bodies of water; the largest producer is Saskatchewan. Wild rice is also produced in Hungary and Australia. In Hungary, cultivation started in 1989.
Manchurian wild rice
Manchurian wild rice, gathered from the wild, was once an important grain in ancient China. It is now very rare in the wild, and its use as a grain has completely disappeared in China, though it continues to be cultivated for its stems.The swollen crisp white stems of Manchurian wild rice are grown as a vegetable, popular in East and Southeast Asia. The swelling occurs because of infection with the smut fungus Ustilago esculenta. The fungus prevents the plant from flowering, so the crop is propagated asexually, the infection being passed from mother plant to daughter plant. Harvest must be made between about 120 days and 170 days after planting, after the stem begins to swell, but before the infection reaches its reproductive stage, when the stem will begin to turn black and eventually disintegrate into fungal spores.
The vegetable is especially common in China, where it is known as gāosǔn or jiāobái. In Japan it is known as makomodake. Other names which may be used in English include coba and water bamboo. Importation of the vegetable to the United States is prohibited in order to protect North American species from the smut fungus.
Nutrition
Wild rice is relatively high in protein, the amino acid lysine and dietary fiber, and low in fat. Nutritional analysis shows wild rice to be the grain second only to oats in protein content per 100 calories. Like true rice, it does not contain gluten. It is also a good source of certain minerals and B vitamins. One cup of cooked wild rice provides 5% or more of the daily value of thiamin, riboflavin, iron, and potassium; 10% or more of the daily value of niacin, vitamin B6, folate, magnesium, phosphorus; 15% of zinc; and over 20% of manganese.Safety
Wild rice seeds can be infected by the highly toxic fungus ergot, which is dangerous if eaten. Infected grains have pink or purplish blotches or growths of the fungus, from the size of a seed to several times larger.Archaeology of Minnesota wild rice
Food source
Anthropologists since the early 1900s have focused on wild rice as a food source, often with an emphasis on the harvesting of the aquatic plant in the Lake Superior region by the Anishinaabe people, also known as the Chippewa, Ojibwa and Ojibwe. The Smithsonian Institution's Bureau of American Ethnology published The Wild Rice Gatherers in the Upper Great Lakes: A Study in American Primitive Economics by Albert Ernest Jenks in 1901. In addition to his fieldwork interviewing members of various tribal communities, Jenks examined the accounts of explorers, fur traders and government agents from the early 1600s to the late 1800s to detail an "aboriginal economic activity which is absolutely unique, and in which no article is employed not of aboriginal conception and workmanship". His study further notes wild rice's importance in the fur-trading era because the region would have been nearly inaccessible if not for the availability of wild rice and the ability to store it for long periods of time. Wild rice's social and economic importance has continued into present times for the Anishinaabe and other north woods tribal members despite the availability of more easily obtainable food sources.Processing by various cultures
The continued use of wild rice from ancient to modern times has provided opportunities to examine the plant's processing by various cultures through the archaeological record they left behind during their occupation of seasonal ricing camps. Early ethnographic reports, tribal accounts and historical writings also inform archaeological research in the human use of wild rice. For example, geographer and ethnologist Henry Schoolcraft in the mid-1800s wrote about depressions in the ground on the shore of a lake with wild rice growing in the water. He wrote that wild rice processors placed animal hides in the holes, filled them with rice and stomped on the rice to thresh it. These jigging pits are part of the husking needed to process wild rice, and archaeologists see these holes in the soil stratigraphy in archaeological excavations today. Such historical records from the post-contact period in the Lake Superior region focus on Anishinaabe harvesting and processing techniques. Archaeological investigations of wild rice processing from the American era, before and after the creation of federal Indian reservations, also provide information on the loss of traditional harvesting areas, as 1800s fur trader and Indian interpreter Benjamin G. Armstrong wrote about outsiders "who claimed to have acquired title to all the swamps and overflowed lakes on the reservations, depriving the Indians of their rice fields, cranberry marshes and hay meadows".Despite the close association of the Anishinaabe and wild rice today, indigenous use of this food for subsistence also predates their arrival in the Lake Superior region. The Anishinaabe today were part of a larger Algonquian group who left eastern North America on a centuries-long journey to the west along the St. Lawrence River and Great Lakes. The Anishinaabe migration story details a vision to follow a giant clam shell in the sky to a place where the food grows on the water. This journey ended between the late 1400s and early 1600s in the Lake Superior wild rice country when they encountered the plant.
