AY Honors/Edible Wild Plants/Amaranth

Template:Redirect Template:TaxoboxAmaranthus, collectively known as amaranth, is a cosmopolitan genus of herbs. Approximately 60 species are recognized, with inflorescences and foliage ranging from purple and red to gold. Members of this genus share many characteristics and uses with members of the closely related genus Celosia.

Although several species are often considered weeds, people around the world value amaranths as leaf vegetables, cereals, and ornamentals. A traditional food plant in Africa, amaranth has the potential to improve nutrition, boost food security, foster rural development and support sustainable landcare.

The ultimate root of "amaranth" is the Greek Template:Polytonic (amarantos) "unfading" with the Greek word for "flower" ἄνθος (anthos) factoring into the word's development as "amaranth" - the more correct "amarant" is an archaic variant.

Systematics

Amaranthus shows a wide variety of morphological diversity among and even within certain species. Although the family (Amaranthaceae) is distinctive, the genus has few distinguishing characters among the 70 species included. This complicates taxonomy and Amaranthus has generally been considered among systematists as a “difficult” genus.

Formerly, Sauer (1955) classified the genus into 2 sub-genera, differentiating only between monoecious and dioecious species: Acnida (L.) Aellen ex K.R. Robertson and Amaranthus. Although this classification was widely accepted, further infrageneric classification was (and still is) needed to differentiate this widely diverse group.

Currently, Amaranthus includes 3 recognized sub-genera and 70 species, although species numbers are questionable due to hybridization and species concepts. Infrageneric classification focuses on inflorescence, flower characters and whether a species is monoecious/dioecious, as in the Sauer (1955) suggested classification. A modified infrageneric classification of Amaranthus was published by Mosyakin & Robertson (1996) and includes 3 subgenera: Acnida, Amaranthus and Albersia. The taxonomy is further differentiated by sections within each of the sub-genera.

Uses

Amaranth Seed

Several species are raised for amaranth "grain" in Asia and the Americas. This should more correctly be termed "pseudograin" (see below). They are highly edible by gluten intolerant individuals because they are not a member of the grass family and contain no gluten.

Ancient amaranth grains still used to this day include the three species, Amaranthus caudatus, Amaranthus cruentus, and Amaranthus hypochondriacus. Although amaranth was (and still is) cultivated on a small scale in parts of Mexico, Guatemala, Peru, India, and Nepal, there is potential for further cultivation in the U.S and tropical countries and it is often referred to as "the crop of the future." It has been proposed as an inexpensive native crop that could be cultivated by indigenous people in rural areas for several reasons: 1) it is easily harvested, 2) it produces lots of fruit and thus seeds, which are used as grain, 3) it is highly tolerant of arid environments, which are typical of most subtropical and some tropical regions, and 4) its seeds contain large amounts of protein and essential amino acids, such as lysine. 5) Amaranthus species are reported to have a 30% higher protein value than cereals, such as rice, wheat flour, oats, and rye. 6) It requires little fuel to cook. As befits its weedy life history, amaranth grains grow very rapidly and their large seedheads can weigh up to 1 kilogram and contain a half-million seeds.

Amaranth was one of the staple foodstuffs of the Incas, and it is known as kiwicha in the Andes today. It was also used by the ancient Aztecs, who called it huautli, and other Native America peoples in Mexico to prepare ritual drinks and foods. To this day, amaranth grains are toasted much like popcorn or martala and mixed with honey, molasses or chocolate to make a treat called alegría (joy in Spanish).

Amaranth grain is a crop of moderate importance in the Himalaya.

Because of its importance as a symbol of indigenous culture, and because it is very palatable, easy to cook, and its protein particularly well suited to human nutritional needs, interest in grain amaranth (especially A. cruentus and A. hypochondriacus) revived in the 1970s. It was recovered in Mexico from wild varieties and is now commercially cultivated. It is a popular snack sold in Mexico City and other parts of Mexico, sometimes mixed with chocolate or puffed rice, and its use has spread to Europe and parts of North America. Amaranth and quinoa are called pseudograins because of their flavor and cooking similarities to grains. These are dicot plant seeds, and both contain exceptionally complete protein for plant sources. Besides protein, amaranth grain provides a good source of dietary fiber and dietary minerals such as iron, magnesium, phosphorus, copper, and especially manganese. It has been claimed to be beneficial in preventing greying of hair.^{[citation needed]}

Vegetables

Amaranth species are cultivated and consumed as a leaf vegetable in many parts of the world. There are 4 species of Amaranthus documented as cultivated vegetables in eastern Asia: Amaranthus cruentus, Amaranthus blitum, Amaranthus dubius, and Amaranthus tricolor.

In Indonesia and Malaysia, leaf amaranth is called bayam, while the Tagalogs in the Philippines call the plant kulitis or Callaloo. In Karnataka state in India it is used to prepare curries like Hulee, palya, Majjigay-hulee and so on. In Tamilnadu State, it is called முளைக்கீரை, and is regularly consumed as a favourite dish, where the greens are steamed, and mashed, with light seasoning of salt, red chillis and cumin. It is called keerai masial (கீரை மசியல்). In Andhra Pradesh, India, this leaf is added in preparation of a popular dal called thotakura pappu తొట కూర పప్పు (Telugu). In Maharashtra, it is called as "Shravani Maath" (literally माठ grown in month of Shravan) and it is available in both red and white colour. In Orissa, it is called as "Khada saga", it is used to prepare 'Saga Bhaja', in which the leaf is fried with chillies and onions.

Root of mature amaranth is an excellent vegetable. It is white in colour and is cooked with tomatoes or tamarind gravy. It has a milky taste and is alkaline.

In China, the leaves and stems are used as a stir-fry vegetable, or in soups, and called yin choi (苋菜; pinyin: xiàncài; and variations on this transliteration in various dialects). Amaranth greens are believed to help enhance eyesight. In Vietnam, it is called rau dền and is used to make soup. There are two species popular as edible vegetable in Vietnam: dền đỏ- amaranthus tricolor and dền cơm or dền trắng- amaranthus viridis.

In East Africa, Amaranth leaf is known in Chewa as Bonongwe, and in Swahili as mchicha, as Terere in Kikuyu, Meru and Embu; and as Telele in Kamba. In Bantu-speaking regions of Uganda it is known as Doodo. It is sometimes recommended by some doctors for people having low red blood cell count. Also known among the Kalenjin as a drought crop (chepkerta). In West Africa such as in Nigeria, it is a common vegetable, and goes with all Nigerian carbohydrate dishes. It is known in Yoruba as efo tete or arowo jeja ("we have money left over for fish"). In CongoTemplate:Clarify it is known as lenga lenga or biteku teku. In the Caribbean, the leaves are called callaloo and are sometimes used in a soup called pepperpot soup.

In Greece, Green Amaranth (Amaranthus viridis) is a popular dish and is called vlita or vleeta. It's boiled, then served with olive oil and lemon like a salad, usually alongside fried fish. Greeks stop harvesting the (usually wild-grown) plant when it starts to bloom at the end of August. In Sri Lanka, it is called "Koora Thampala". Sri Lankans cook it and eat it with rice. Fiji Indians call it choraiya bhaji.

Dyes

The flowers of the 'Hopi Red Dye' amaranth were used by the Hopi (a tribe in the western United States) as the source of a deep red dye. There is also a synthetic dye that has been named "amaranth" for its similarity in color to the natural amaranth pigments known as betalains. This synthetic dye is also known as Red No. 2 in North America and E123 in the European Union.

Ornamentals

The genus also contains several well-known ornamental plants, such as Amaranthus caudatus (love-lies-bleeding), a native of India and a vigorous, hardy annual with dark purplish flowers crowded in handsome drooping spikes. Another Indian annual, A. hypochondriacus (prince's feather), has deeply veined lance-shaped leaves, purple on the under face, and deep crimson flowers densely packed on erect spikes.

Amaranths are recorded as food plants for some Lepidoptera (butterfly and moth) species including the nutmeg moth and various case-bearer moths of the genus Coleophora: C. amaranthella, C. enchorda (feeds exclusively on Amaranthus), C. immortalis (feeds exclusively on Amaranthus), C. lineapulvella and C. versurella (recorded on A. spinosus).

Nutritional value

Amaranth greens, also called Chinese spinach, hinn choy or yin tsoi (Template:Zh); callaloo, dhantinasoppu (Kannada); తోటకూర (Telugu); Rajgira (Marathi); முளைக் கீரை (Tamil), cheera ചീര (Malayalam); bayam (Indonesian); phak khom ผักโขม (Thai); tampala, or quelite, (Oriya); Khada Saga, are a common leaf vegetable throughout the tropics and in many warm temperate regions. It is very popular in India. They are a very good source of vitamins including vitamin A, vitamin K, vitamin B6, vitamin C, riboflavin, and folate, and dietary minerals including calcium, iron, magnesium, phosphorus, potassium, zinc, copper, and manganese. Because of its valuable nutrition, some farmers grow amaranth today. However their moderately high content of oxalic acid can inhibit the absorption of calcium and zinc, and also indicates that they should be eaten with caution under consultation with healthcare providers by people with kidney disorders, gout, or rheumatoid arthritis, concerning mineral absorption and supplementation.^{[citation needed]} Reheating cooked amaranth greens is often discouraged, particularly for consumption by small children, as the nitrates in the leaves can be converted to nitrites, similarly to spinach.^{[citation needed]}

Amaranth seeds, like buckwheat and quinoa, contain protein that is unusually complete for plant sources. Most fruits and vegetables do not contain a complete set of amino acids, and thus different sources of protein must be used.

Its seeds have a protein content greater than that of wheat. However, unlike that found in true grains (i.e. from grass seeds) its protein is not of the problematical type known as gluten.

Several studies have shown that like oats, amaranth seed or oil may be of benefit for those with hypertension and cardiovascular disease; regular consumption reduces blood pressure and cholesterol levels, while improving antioxidant status and some immune parameters. While the active ingredient in oats appears to be water-soluble fiber, amaranth appears to lower cholesterol via its content of plant stanols and squalene.

As a weed

Not all amaranth plants are cultivated. Most of the species from Amaranthus are summer annual weeds and are commonly referred to as pigweeds. These species have an extended period of germination, rapid growth, and high rates of seed production and have been causing problems for farmers since the mid-1990s. This is partially due to the reduction in tillage, reduction in herbicidal use and the evolution of herbicidal resistance in several species where herbicides have been applied more often. The following 9 species of Amaranthus are considered invasive and noxious weeds in the U.S and Canada: A. albus, A. blitoides, A. hybridus, A. palmeri, A. powellii, A. retroflexus, A. spinosus, A. tuberculatus, and A. viridis.

A new herbicide-resistant strain of Amaranthus palmeri or Palmer amaranth has appeared; it is Glyphosate-resistant and so cannot be killed by the widely used Roundup herbicide. Also, this plant can survive in tough conditions. This could be of particular concern to cotton farmers using Roundup Ready cotton. The species Amaranthus palmeri (Palmer amaranth) causes the greatest reduction in soybean yields and has the potential to reduce yields by 17-68% in field experiments. Palmer amaranth is among the “top five most troublesome weeds” in the southeast and has already evolved resistances to dinitroanilines and acetolactate synthase inhibitors. This makes the proper identification of Amaranthus species at the seedling stage essential for agriculturalists. Proper herbicide treatment needs to be applied before the species successfully colonizes in the crop field and causes significant yield reductions.

Beneficial weed

Pigweed can be a beneficial weed, as well as a companion plant, serving as a trap for leaf miners and some other pests, as well as sheltering ground beetles (which prey upon insect pests) and breaking up hard soil for more delicate neighboring plants.

Myth, legend and poetry

Amaranth, or Amarant (from the Greek amarantos, unwithering), a name chiefly used in poetry, and applied to Amaranth and other plants which, from not soon fading, typified immortality.

Aesop's Fables (6th century BC) compares the Rose to the Amaranth to illustrate the difference in fleeting and everlasting beauty.

A Rose and an Amaranth blossomed side by side in a garden,

and the Amaranth said to her neighbour,

"How I envy you your beauty and your sweet scent!

No wonder you are such a universal favourite."

But the Rose replied with a shade of sadness in her voice,

"Ah, my dear friend, I bloom but for a time:

my petals soon wither and fall, and then I die.

But your flowers never fade, even if they are cut;

for they are everlasting."

Or in story mode:

An amaranth planted in a garden near a Rose-Tree, thus addressed it: "What a lovely flower is the Rose, a favorite alike with Gods and with men. I envy you your beauty and your perfume." The Rose replied, "I indeed, dear Amaranth, flourish but for a brief season! If no cruel hand pluck me from my stem, yet I must perish by an early doom. But thou art immortal and dost never fade, but bloomest for ever in renewed youth."

Thus, in John Milton's epic poem Paradise Lost (1667), iii. 353:

"Immortal amarant, a flower which once

In paradise, fast by the tree of life,

Began to bloom; but soon for man's offence

To heaven removed, where first it grew, there grows,

And flowers aloft, shading the fount of life,

And where the river of bliss through midst of heaven

Rolls o'er elysian flowers her amber stream:

With these that never fade the spirits elect

Bind their resplendent locks."

Samuel Taylor Coleridge, in Work Without Hope (1825), also refers to the herb, likely referencing Milton's earlier work. (ll 7-10 excerpted):

Yet well I ken the banks where Amaranths blow,

Have traced the fount whence streams of nectar flow.

Bloom, O ye Amaranths! bloom for whom ye may,

For me ye bloom not! Glide, rich streams, away!

Joachim du Bellay mentioned the herb in his "A Vow To Heavenly Venus," ca. 1500.

We that with like hearts love, we lovers twain,

New wedded in the village by thy fane,

Lady of all chaste love, to thee it is

We bring these amaranths, these white lilies,

A sign, and sacrifice; may Love, we pray,

Like amaranthine flowers, feel no decay;

Like these cool lilies may our loves remain,

Perfect and pure, and know not any stain;

And be our hearts, from this thy holy hour,

Bound each to each, like flower to wedded flower.

The original spelling is amarant; the more common spelling amaranth seems to have come from a folk etymology assuming that the final syllable derives from the Greek word anthos ("flower"), common in botanical names.

In ancient Greece, the amaranth (also called chrysanthemum and helichrysum) was sacred to Ephesian Artemis. It was supposed to have special healing properties, and as a symbol of immortality was used to decorate images of the gods and tombs. In legend, Amarynthus (a form of Amarantus) was a hunter of Artemis and king of Euboea; in a village of Amarynthus, of which he was the eponymous hero, there was a famous temple of Artemis Amarynthia or Amarysia (Strabo x. 448; Pausan. i. 31, p. 5). It was also widely used by the Chinese for its healing chemicals, curing illnesses such as infections, rashes, and migraines. The "Amarantos" is the name of a several-century-old popular Greek folk song:

Look at the amaranth:

on tall mountains it grows,

on the very stones and rocks

and places inaccessible.

In Popular Culture

• In Abhorsen, Amaranth is, along with Rosemary, the smell of Astrael - one of the 9 Bright Shiners and one of the seven who gave themselves to the creation of the Charter (but one of the two who wasn't consumed):

"It's rosemary," said the Dog shortly. "And there is amaranth, too, though you probably cannot smell it." "Fidelity in love," said a small voice from Sam's backpack. "With the flower that never fades. And you still say she is not there?"

Orson Scott Card's novel Speaker for the Dead features a plant called amaranth, genetically modified to survive on the planet Lusitania, where the majority of the story takes place.

In Vampire: The Masquerade lore, an amaranth placed on the bed of a vampire was the warning of Diablerie soon to come. The act of Diablerie was also referred to as "Amaranth".

Noted British motorcycle designer, Edward Turner chose Amaramth Red as the colour for his revolutionary 1938 Triumph Speed Twin in memory of his late first wife's appreciation of its bloom. The model kept this colour throughout its model run and initially upon re-design in 1959.
