Colocasia esculenta is a tropical plant grown primarily for its edible corms, the root vegetables most commonly known as taro. It is believed to be one of the earliest cultivated plants. Linnaeus originally described two species which are now known as Colocasia esculenta and Colocasia antiquorum of the cultivated plants that are known by many names including eddoes, dasheen, taro and madumbi, but many later botanists consider them all to be members of a single, very variable species, the correct name for which is Colocasia esculenta.
Taro () commonly refers to the plant Colocasia esculenta, the most widely cultivated species of several plants in the Araceae family which are used as vegetables for their corms, leaves, and petioles.
Colocasia esculenta is thought to be native to Southern India and Southeast Asia, but is widely naturalised. It is a perennial, tropical plant primarily grown as a root vegetable for its edible starchy corm, and as a leaf vegetable. It is a food staple in African, Oceanic and Indian cultures and is believed to have been one of the earliest cultivated plants. Colocasia is thought to have originated in the Indomalaya ecozone, perhaps in East India, Nepal, and Bangladesh, and spread by cultivation eastward into Southeast Asia, East Asia and the Pacific Islands; westward to Egypt and the eastern Mediterranean Basin; and then southward and westward from there into East Africa and West Africa, where it spread to the Caribbean and Americas. It is known by many local names and often referred to as "elephant ears" when grown as an ornamental plant.

Taxonomy
The specific epithet, esculenta, means "edible" in Latin.
Taro is related to Xanthosoma and Caladium, plants commonly grown as ornamentals, and like them it is sometimes loosely called elephant ear.
Description
Rhizomes of different shapes and sizes. Leaves up to 40×24.8 cm, sprouts from rhizome, dark green above and light green beneath, triangular-ovate, sub-rounded and mucronate at apex, tip of the basal lobes rounded or sub-rounded. Petiole 0.8 -1.2 m high. Spathe up to 25 cm long. Spadix about 3/5 as long as the spathe, flowering parts up to 8 mm in diameter. Female portion at the fertile ovaries intermixed with sterile white ones. Neuters above the females, rhomboid or irregular oblong. Male portion above the neuter. Synandrium lobed, cells 6 or 8. Appendage shorter than the male portion.
Distribution and habitat
Taro was probably first native to the lowland wetlands of Malaysia (taloes). Estimates are that taro was in cultivation in wet tropical India before 5000 BC, presumably coming from Malaysia, and from India further transported westward to ancient Egypt, where it was described by Greek and Roman historians as an important crop.
In Australia, Colocasia esculenta var. aquatilis is native to the Kimberley region of Western Australia; variety esculenta is naturalised in Western Australia, the Northern Territory, Queensland and New South Wales.
In Turkey, Colocasia esculenta is locally known as "gölevez" and mainly grown on the Mediterranean coast, such as the Alanya & Anamur district of Antalya.
In the southeastern USA, this plant is recognized as an invasive species.
Cultivation
Taro can be grown in paddy fields where water is abundant or in upland situations where water is supplied by rainfall or supplemental irrigation. Taro is one of the few crops (along with rice and lotus) that can be grown under flooded conditions. This is due to air spaces in the petiole, which permit underwater gaseous exchange with the atmosphere. For a maximum dissolved oxygen supply, the water should be cool and flowing. Warm, stagnant water causes basal rotting. For maximum yields, the water level should be controlled so that the base of the plant is always under water.
Flooded cultivation has some advantages over dry-land cultivation: higher yields (about double), out-of-season production (which may result in higher prices), and weed control (which flooding facilitates). On the other hand, in flooded production systems taro requires a longer maturation period, investment in infrastructure, and higher operational costs, and monoculture is likely.
Like most root crops, taro and eddoes do well in deep, moist or even swampy soils where the annual rainfall exceeds 2,500 mm. Eddoes are more resistant to drought and cold. The crop attains maturity within six to twelve months after planting in dry-land cultivation and after twelve to fifteen months in wetland cultivation. The crop is harvested when the plant height decreases and the leaves turn yellow. These signals are usually less distinct in flooded taro cultivation.
Harvesting is usually done by hand tools, even in mechanized production systems. First, the soil around the corm is loosened, and then, the corm is pulled up by grabbing the base of the petioles. The global average yield is 6.2 tones/hectare but varies according to the region. In Asia, average yields reach 12.6 tones/hectare.
Uses
Taro's primary use is the consumption of its edible corm and leaves. In its raw form, the plant is toxic due to the presence of calcium oxalate, and the presence of needle-shaped raphides in the plant cells. However, the toxin can be minimized and the tuber rendered palatable by cooking, or by steeping in cold water overnight.
Corms of the small round variety are peeled and boiled, sold either frozen, bagged in its own liquids, or canned. The leaves are rich in vitamins and minerals. It is also sold as an ornamental aquatic plant.
It is also used for Anthocyanin study experiments especially with reference to abaxial and adaxial anthocyanic concentration.
The corms, which have a light purple color due to phenolic pigments, are roasted, baked or boiled, and the natural sugars give a sweet nutty flavor. The starch is easily digestible, and since the grains are fine and small it is often used for baby food. Young taro leaves and stems can be eaten after boiling twice to remove the acrid flavor, and the leaves are a good source of vitamins A and C and contain more protein than the corms.
Azores
In the Azores taro is known as inhame or inhame-coco and is commonly steamed with potatoes, vegetables and meats or fish. It is also consumed as a dessert after first being steamed and peeled, then fried in vegetable oil or lard, and finally sprinkled with sugar. Taro grows in the fertile land of the Azores, as well as in creeks that are fed by mineral springs. Through migration to other countries, the inhame is found in the Azorean diaspora.
Bangladesh
In Bangladesh taro is a very popular vegetable known as kochu (???) or mukhi (????). It is usually cooked with small prawns or the ilish fish into a curry, but some dishes are cooked with dried fish. Its green leaves, kochu pata (??? ????), and stem, kochu (???), are also eaten as a favourite dish and usually ground to a paste or finely chopped to make shak - but it must be boiled well beforehand. Taro stolons or stems, kochur loti (???? ???), are also favoured by Bangladeshis and cooked with shrimp, dried fish or the head of the ilish fish. Taro is available, either fresh or frozen, in the UK and US in most Asian stores and supermarkets specialising in Bangladeshi or South Asian food. Also, another variety called maan kochu is consumed and is a rich source of vitamins and nutrients. Maan Kochu is pasted and fried to prepare a delicious food known as Kochu Bata.
Brazil
In Lusophone countries, inhame (pronounced [? ' ????mi], [' ????mi] or [??'???mi], literally "yam") and cará are the common names for various plants with edible parts of the genera Alocasia, Colocasia (family Araceae) and Dioscorea (family Dioscoreaceae), and its respective starchy edible parts, generally tubers, with the exception of Dioscorea bulbifera, called cará-moela (pronounced [k?'?a mu'?l?], literally, "gizzard yam"), in Brazil and never deemed to be an inhame. Definitions of what constitutes an inhame and a cará vary regionally, but the common understanding in Brazil is that carás are potato-like in shape, while inhames are more oblong.
In the "broad" lower class Brazilian Portuguese of the hotter and drier Northeastern region, both inhames and carás are called batata (literally, "potato"). For differentiation, potatoes are called batata-inglesa (literally, "English potato"), a name used in other regions and sociolects to differentiate it from the batata-doce, "sweet potato", ironic names since both were first cultivated by the indigenous peoples of South America, their native continent, and only later introduced in Europe by the colonizers.
Taros are often prepared like potatoes, eaten boiled, stewed or mashed, generally with salt and sometimes garlic as condiment, as part of a meal (most often lunch or dinner).
Chinese cuisine
China
Taro (simplified Chinese: ??; traditional Chinese: ??; pinyin: yùtou; Cantonese Yale: wuhtáu), is commonly used as a main course as steamed taro with or without sugar, as a substitute for other cereals, in Chinese cuisine in a variety of styles and provinces steamed, boiled or stir fried as a main dish and as a flavor enhancing ingredient. In Northern China it is often boiled or steamed then peeled and eaten with or without sugar much like a potato. It is commonly braised with pork or beef. It is used in the dim sum cuisine of southern China to make a small plated dish called taro dumpling as well as a pan-fried dish called taro cake. It can also be shredded into long strips which are woven together to form a seafood birdsnest.
Taro cake is a delicacy traditionally eaten during Chinese New Year celebrations. As a dessert, it can be mashed into a purée or used as flavoring in tong sui, bubble tea, ice cream, and other desserts such as Sweet Taro Pie. McDonald's sells taro-flavored pies in China.
Taro is mashed in the dessert known as taro purée.
Taiwan
In Taiwan, taro is called ?? (yùtóu) in Mandarin, or ?? (??-á) in Taiwanese. Taro is well-adapted to Taiwanese climate and can grow almost anywhere with minimal maintenance. Before the Taiwan Miracle made rice affordable to everyone, taro was one of the main staple foods in Taiwan. Nowadays taro is used more often in desserts. Supermarket varieties range from about the size and shape of a brussels sprout to longer, larger varieties the size of a football. Taro chips are often used as a potato chip-like snack. Compared to potato chips, taro chips are harder and have a nuttier flavor. Other popular traditional Taiwanese taro snacks are taro balls served on ice or deep-fried.
Cook Islands
Taro is the pre-eminent crop of the Cook Islands, and surpasses all other crops in terms of land area devoted to production. The prominence of the crop in the Cook Islands has also led to it being a staple of the population?s diet. Taro is grown across the country, but the method of cultivation depends on the nature of the island it is grown upon. Taro also plays an important role in the export trade of the country. The root is eaten boiled, as is standard across Polynesia. Taro leaves are also eaten as a delicacy, cooked with coconut milk, onion and meat or fish.
Costa Rica, Nicaragua and Panama
In Costa Rica, Nicaragua and Panama, taro is eaten in soups, as a replacement for potatoes, and as chips. It is known locally as malanga (also malanga coco) in Costa Rica, quiquizque in Nicaragua, and as "otoe" in Panama.
East Africa
In Kenya, Uganda and Tanzania, taro is commonly known as arrow root, ggobe, or nduma and madhumbe in some local Bantu languages. It is usually boiled and eaten with tea or other beverages, or as the main starch of a meal. It is also cultivated in Malawi, Mozambique, and Zimbabwe.
Egypt
In Egypt, taro is known as Qolqas (Egyptian Arabic: ??????, IPA: [?ol'?æ:s]). The corms are larger than what would be found in North American supermarkets. After being peeled completely, it is cooked in one of two ways. It is cut into small cubes and cooked in broth with fresh coriander and chard and served as an accompaniment to meat stew, or it may be sliced and cooked with minced meat and tomato sauce.
In the army, the black dish (?????? ?????? al-?abkha al-sawda) is a combination of eggplants and unpeeled taro halves.
Europe
Taro was consumed by the early Romans in much the same way the potato is today. They called this root vegetable colocasia. The Roman cookbook Apicius mentions several methods for preparing taro, including boiling, preparing with sauces, and cooking with meat or fowl. After the fall of the Roman Empire the use of taro dwindled in Europe. This was largely due to the decline of trade and commerce with Egypt, previously controlled by Rome. It is still important to note the Taro because when the Spanish and Portuguese sailed to the new world, they brought taro along with them. Taro has remained popular in the Canary Islands. Recently there has been renewed interest in exotic foods and consumption is increasing.
Cyprus
In Cyprus, taro has been in use since the time of the Roman Empire. Today it is known as kolokasi (????????), which comes from the Ancient Greek name ?????????? ("kolokasion") for lotus root. It is usually sauteed with celery and onion with pork or chicken, in a tomato sauce - a vegetarian version is also available. "Baby" taro is called "poulles" on the island, and after being sauteed the vessel is decaramelised with dry red wine and coriander seeds, then served with freshly squeezed lemon.
Greece
In Greece, taro grows on Icaria. Icarians credit taro for saving them from famine during World War II. They boil it until tender and serve it as a salad.
Spain
Taro root is consumed in the south of Spain. Taro is called ñame (which normally designates yams) in Canarian Spanish and is a common crop in the Autonomous Community of the Canary Islands (Canary Islands, Spain).
Fiji
Taro (dalo in Fijian) has been a staple of the Fijian diet for centuries, and its cultural importance is celebrated on Taro Day. Its growth as an export crop can be said to have begun in 1993 when the taro leaf blight (Phytophthora colocasiae) decimated the taro industry in neighboring Samoa. Fiji filled the void and was soon supplying taro internationally. Almost 80% of Fiji's exported taro comes from the island of Taveuni where the taro beetle species (Papuana uninodis) is absent. The Fijian taro industry on the main islands of Viti Levu and Vanua Levu faces constant damage from the beetles. The Fiji Ministry of Agriculture and the Land Resources Division of the Secretariat of the Pacific Community (SPC) are researching pest control and instigating quarantine restrictions to prevent spread of the pest. Taveuni now exports pest damage-free crops.
Hawaii
Kalo is the Hawaiian name for the Taro plant. The local crop plays an important role in Hawaiian culture, mythology, and cuisine. Kalo is a traditional staple of the native cuisine of Hawaii. Some of the uses for taro include poi, table taro (steamed and served like a potato), taro chips, and luau leaf (to make laulau)). In Hawaii, kalo is farmed under either dryland or wetland conditions. Taro farming in the Hawaiian Islands is challenging owing to the difficulties of accessing fresh water. Kalo is usually grown in "pond fields" known as lo?i. Cool, flowing water yields the best crop. Typical dryland or "upland" varieties (varieties grown in watered but not flooded fields) in Hawaii are lehua maoli and bun long, the latter widely known as "Chinese taro". Bun long is used for making taro chips. Dasheen (also called "eddo") is another dryland variety of C. esculenta grown for its edible corms or just as an ornamental plant. A contemporary Hawaiian diet consists of many tuberous plants, particularly sweet potato and kalo.
The Hawaii Agricultural Statistics Service determined the 10-year median production of kalo in Hawaii to be about 6.1 million pounds (2,800 t). However, 2003 taro production in Hawaii was only 5 million pounds (2,300 t), an all-time low since record-keeping started in 1946. The previous low of 1997 was 5.5 million pounds (2,500 t). Despite generally growing demand, production was even lower in 2005--only 4 million pounds, with kalo for processing into poi accounting for 97.5%. Urbanization is one cause driving down harvests from the high of 14.1 million pounds (6,400 t) in 1948, but more recently, the decline has resulted from pests and diseases. A nonnative apple snail (Pomacea canaliculata) is a major culprit along with a plant rot disease traced to a newly identified species of Fungus in the genus Phytophthora that now affects kalo crops throughout Hawaii. Although pesticides could control both problems to some extent, pesticide use in the lo?i is banned because of the opportunity for chemicals to migrate quickly into streams, and then eventually the sea.
Social issue.
Important aspects of Hawaiian culture revolve around kalo cultivation and consumption. For example, the newer name for a traditional Hawaiian feast (luau) comes from the kalo. Young kalo tops baked with coconut milk and chicken meat or octopus arms are frequently served at luaus.
By ancient Hawaiian custom, fighting is not allowed when a bowl of poi is "open". Similarly, it is also considered disrespectful to fight in front of an elder and one should not raise their voice, speak angrily, or make rude comments/gestures. An "open" poi bowl is connected to this concept because H?loa (kalo) is the name of the firstborn son of the parents who begat the entire human race under Hawaiian legend. Hawaiians identify strongly with kalo. In fact, the Hawaiian term for family, ?ohana, is derived from ?oh?, the shoot or sucker which grows from the kalo corm. The reason being: as young shoots grow from the corm of the kalo plant, so people, too, grow from their family.
Lo?i
A lo?i is a patch of wetland dedicated to growing kalo. Hawaiians have traditionally used water irrigation systems to produce kalo. Wetland fields produce ten to fifteen times more kalo per acre than dry fields. Wetland-grown kalo need a constant flow of water, and to get this water, fields are usually positioned between the mauka (mountains) and makai (sea). Note: lo'i specifically denotes wetland kalo growing, not dry land.
The lo?i is part of an ahupua?a, a division of land from the mountain to the sea. Ahupua?a means "pig altar," and was named for stone altars with pig head carvings that marked the boundaries of each Hawaiian land division. Ideally, an ahuapua?a has all necessities in its borders. From the mountains, materials such as wood are provided for thatching roofs and twining rope. The uplands produce crops like sugar cane and sweet potatoes, while the lowlands provide taro and fish. This system typically satisfies the large populations in each ahupua?a.
When kalo was brought to Hawai?i, there were about 300 varieties (about 100 remain).The kalo plant takes seven months to grow until harvest, so lo`i fields are used in rotation and the soil can be replenished while the lo?i in use has sufficient water. The stems are typically replanted in the lo`i for future kalo harvests. Once harvested, kalo is incorporated into many foods. The leaves are used to make laulau, the corm poi or pa?i?ai, but in order for the plant to be edible, the leaves and the corm must be steamed. Both of these plant parts contain calcium oxalate, which can be harmful if consumed in high amounts. The leaves or furry corms are even known to cause irritation of the skin and pruritus when touched.
History
One mythological version of Hawaiian ancestry cites the taro plant as an ancestor to Hawaiians. Legend joins the two siblings of high and divine rank: Papah?naumoku ("Papa from whom lands are born", or Earth mother) and W?kea (Sky father). Together they create the islands of Hawaii and a beautiful woman, Ho?ohokukalani (The Heavenly one who made the stars).
The story of kalo begins when Wakea and Papa conceived their daughter, Ho?ohokukalani. Daughter and father then conceived a child together named H?loanakalaukapalili (Long stalk trembling), but it was stillborn. After the father and daughter buried the child near their house, a kalo plant grew over the grave:
The stems were slender and when the wind blew they swayed and bent as though paying homage, their heart-shaped leaves shivering gracefully as in hula. And in the center of each leaf water gathered, like a mother's teardrop.
The second child born of Wakea and Ho?ohokukalani was named H?loa after his older brother. The kalo of the earth was the sustenance for the young brother and became the principal food for successive generations. Now, as man continues to work the wetlands for this sacred crop, he remembers Haloanaka, the ancestor that nourishes him.
India
In India, taro or eddoe is a common dish served in many ways.
It is called Arvi in Urdu/Hindi in Central & North India, which is often mispronounced as Arbi.
It is called ???(kachu) in Sanskrit.
In Mizoram, it is called bäl; the leaves, stalks and tubers are eaten as dawl bai. The leaves and stalks are often traditionally preserved to be eaten in dry season as "dawl rëp bai".
In Assam, a north-eastern state of India, taro is known as "kosu". Various parts of different types of such plants are eaten by making different dishes. The leave buds called "Kosu lati" are cooked with sour dried fruits called "Thekera" or sometimes with Tarmarind or Elephant apple alone or with little amount of pulses and sometimes, fishes. Similar dishes are prepared from long root like structures called "Kosu thuri". A fried dish with sour objects is also made from its flower (Kosu kala). Soupy dishes are made from solid roots which sometimes is also boiled and taken sometimes with salt as snacks or home-made fast food.
In Manipur, another north-eastern state of India, taro is known as "pan".The kuki tribes called it "bal". Boiled "bal" is snacked as lunch along with chutney or hot chilli-flakes besides cooked as a main dish along with smoked or dried meat, beans, mustard leaves.They also sundried the leaves and keep it for future use as broth and hodge-podge. It is widely available and is eaten in many forms, either baked, boiled, and cooked into a curry with Hilsa fish or with fermented soyabeans called "Hawai-zaar". The leaves are also used in a special traditional dish called "utti", cooked with peas.
In Himachal Pradesh, a northern state in India, taro is known as ghandyali in Mandi district. The dish called patrodu is made from the leaves of the ghandyali. Also in the capital Shimla, a pancake-style dish, called patra or patid, is made using gram flour.
A tall-growing variety of taro is extensively used on the western coast of India to make patrode, patrade, or patrada, literally a "leaf-pancake". In Dakshin Kannada district in the state of Karnataka, it is used as a morning breakfast dish, either made like fritters, or steamed. In the state of Maharashtra, the leaves, called alu che paana, are de-veined, rolled with a paste of gram flour, tamarind paste, red chili powder, turmeric, coriander, asafoetida, and salt, and then steamed. These can be eaten whole or cut into pieces, or shallow fried and eaten as a snack known as alu chi wadi. Alu chya panan chi patal bhaji a lentil and colocasia leaves curry, is also popular.In Goan cuisine as well as the Konkani cuisine Taro leaves are very popular.
In the Indian states of Gujarat and Maharashtra, the leaves of the plant are used to make patra a dish with gram flour, tamarind and other spices.
Sindhis call it kachaloo; they fry it, compress it, and re-fry it to make a dish called tuk which complements Sindhi curry.
In Kerala, a state in southern India, taro corms are known as ?????? ??????? chembu-kizhangu. Taro is used as a staple food, as a side dish, or as an ingredient in various side dishes like sambar. As a staple food, it is steamed and eaten with a spicy chutney of green chillies, tamarind, and shallots. The leaves and stems of certain varieties of taro are used as a vegetable in Kerala.
In other Indian states, Tamil Nadu and Andhra Pradesh, taro corms are known as sivapan-kizhangu (seppankilangu or cheppankilangu), chamagadda, or in coastal Andhra districts as chaama dumpa in Telugu, and it can be cooked in many ways, such as deep fried in oil for a side item with rice, or cooked in a tangy tamarind sauce with spices, onion, and tomato.
In the East Indian state of West Bengal, taro roots are thinly sliced and fried to make chips called kochu bhaja. The stem is used to cook a very tasty Kochur saag with fried hilsha fish head or boiled chhola (chickpea), often eaten as a starter with hot rice. The roots are also made into a paste with spices and eaten with rice. The most popular dish is a spicy curry made with prawn and taro roots.
In Mithilanchal region of Bihar, taro root is known as ???? and its leaves are called ??????? ?? ???. the curry of taro leave is made with mustard paste and ???? (dried mango pulp in sun for sour taste in Daal, curry and sour gravy) .
In the eastern Indian state of Odisha, taro root is known as saru. Dishes made of taro include saru besara (taro in mustard and garlic paste). It is also an indispensable ingredient in preparing the heart of Odia cuisine, the dalma, where vegetables are cooked with dal. Sliced taro roots, deep fried in oil and mixed with red chili powder and salt, are known as saru chips.
In the north Indian state of Uttarakhand and neighbouring Nepal, taro is considered a healthy food cooked in a variety of ways. The delicateGaderi taro of Kumaun, especially from Lobanj region is much sought after. Most commonly it is boiled in tamarind water till tender, then cubes are diced out, which are stir fried in mustard oil with methi (fenugreek) leaves. Boiling it in salty water in iron cooking pots until it becomes like porridge, is another technique. The young leaves, called gaaba, are steamed, then sun-dried and stored for later use. For another use, the taro leaves and stems are used raw as an ingredient for pickles. Crushed leaves and stems are mixed with de-husked urad dal - black lentils and then dried as small balls called badi. The stems may also be sun-dried and stored for later use. On one special day, women worship saptarshi ("seven sages") and eat only rice with taro leaf vegetable.
Japan
A similar plant in Japan is called satoimo (???????, literally "village potato"). The "child" and "grandchild" corms (cormels, cormlets) which bud from the parent satoimo, are called koimo (??) and magoimo (??), respectively, or more generally imonoko (???). Satoimo has been propagated in Southeast Asia since the late J?mon period. It was a regional staple food before rice became predominant. The tuber, satoimo, is often prepared through simmering in fish stock (dashi) and soy sauce. The stalk, zuiki, can also be prepared a number of ways, depending on the variety.
Korea
In Korea, taro is called toran (Korean: ??: "egg from earth"), and the corm is stewed and the leaf stem is stir-fried. Taro roots can be used for medicinal purposes, particularly for treating insect bites. It is made into the Korean traditional soup toranguk (???). Taro stems are often used as an ingredient in yukgaejang (???).
Lebanon
In Lebanon, taro is known as "kilkass" and is mainly grown along the Mediterranean coast. The leaves and stems are not consumed in Lebanon and the variety grown produces round to slightly oblong tubers that vary in size from a tennis ball to a small cantaloupe. Kilkass is a very popular winter dish in Lebanon and is prepared in two ways: "kilkass with lentils" is a stew flavored with crushed garlic and lemon juice and "'il'as (?????) bi-tahini". Another common method of preparing taro is to boil, peel then slice it into 1 cm thick slices, before frying and marinating in edible "red" sumac. In northern Lebanon, it is known as a potato with the name Borshoushi (El-Orse Borshushi). It is also prepared as part of a lentil soup with crushed garlic and lemon juice. Also in the north, it is known by the name "Bouzmet", mainly around Menieh town, where it is first peeled, and left to dry in the sun for a couple of days. After that, it is stir fried in lots of vegetable oil in a casserole till golden brown, then a big amount of wedged, welted onions are added, in addition to water, chickpeas and some seasoning. These are all left to simmer for a few hours, and the result is a stew-like dish. It is considered a hard to make delicacy, not only because of the tedious preparation, but the consistency and flavour that the taro must reach. The smaller variety of taro is more popular in the north due to its tenderness.
Maldives
Ala was widely grown in southern atolls of Addu Atoll, Fuvahmulah, Huvadhu Atoll, and Laamu Atoll and is considered a staple food even after rice was introduced. Ala and olhu ala are still widely eaten all over Maldives, cooked or steamed with salt to taste and eaten with grated coconut along with chili paste and fish soup. It is also prepared as a curry. The roots are sliced and fried to make chips and are also used to prepare varieties of sweets.
Nepal
Taro is grown in the Terai and hilly regions of Nepal. The root (corm) of taro is known as pindalu (???????) and petioles with leaves are known as karkalo (??????) and also as Gava (????). Almost all parts are eaten in different dishes. Boiled corm of Taro is commonly served with salt, spices and chillies. Taro is a popular dish in hilly region. Chopped leaves and petioles are mixed with Urad bean flour to make dried balls called maseura (???????). Large taro leaves are used as an alternative to an umbrella when unexpected rain occurs. Popular attachment to taro since ancient times is reflected in popular culture, such as in songs and textbooks. Jivan hamro karkala ko pani jastai ho (???? ?????? ???????? ???? ????? ??) means, "Our life is as vulnerable as water stuck in the leaf of taro".
Taro is cultivated and eaten by Tharu people in the Inner Terai as well. Roots are mixed with dried fish and turmeric, then dried in cakes called sidhara which are curried with radish, chile, garlic and other spices to accompany rice. The Tharu prepare the leaves in a fried vegetable side-dish that also shows up in Maithili cuisine.
Philippines
Taro is called gabi in the Philippines and is widely available throughout the archipelago. Its adaptability to marshland and swamps make it one of the most common vegetables in the Philippines. The leaves, stems, and corms are all consumed and form part of the local cuisine. A popular recipe for taro is laing; the dish's main ingredients are taro leaves (at times including stems) cooked in coconut milk, and salted with fermented shrimp or fish bagoong. It is sometimes heavily spiced with red hot chilies called siling labuyo. Another dish in which taro is commonly used is the Philippine national stew, sinigang, although radish can be used if taro is not available. This stew is made with pork and beef, shrimp, or fish, a souring agent (tamarind fruit, kamias, etc.) with the addition of peeled and diced corms as thickener. The corm is also prepared as a basic ingredient for ginataan, a coconut milk and taro dessert.
Pakistan
In Pakistan, taro or eddoe or arvi is a very common dish served with or without gravy; a popular dish is arvi gosht, which includes beef, lamb or mutton. The leaves are rolled along with gram flour batter and then fried or steamed to make a dish called Pakora, which is finished by tempering with red chillies and carrom (ajwain) seeds. Taro or Arvi is also cooked with chopped spinach. The dish called "Arvi Palak" is the second most renowned dish made of Taro.
Papua New Guinea
The Taro corm is a traditional staple food crop for large parts of Papua New Guinea, with domestic trade extending its consumption to areas where it is not traditionally grown. Taro from some regions have developed particularly good reputations with (for instance) Lae taro being highly prized.
Among the Urapmin people of Papua New Guinea, taro (known in Urap as ima) is the main source of sustenance along with the sweet potato (Urap: wan). In fact, the word for "food" in Urap is a compound of these two words.
Polynesia
Considered the staple starch of traditional Polynesian cuisine, taro is both a common and prestigious food item that was first introduced to the Polynesian islands by prehistoric seafarers of Southeast Asian derivation. The tuber itself is prepared in various ways, including baking, steaming in earth ovens (umu or imu), boiling, and frying. The famous Hawaiian staple poi is made by mashing steamed taro roots with water. Taro also features in traditional desserts such as Samoan "fa'ausi", which consists of grated, cooked taro mixed with coconut milk and brown sugar. The leaves of the taro plant also feature prominently in Polynesian cooking, especially as edible wrappings for dishes such as Hawaiian laulau, Fijian and Samoan "palusami" (wrapped around onions and coconut milk), and Tongan "lupulu" (wrapped corned beef). Ceremonial presentations on occasion of chiefly rites or communal events (weddings, funerals, etc.) traditionally included ritual presentation of raw and cooked taro roots/plants. The Hawaiian laulau traditionally contains pork, fish, and lu'au (cooked taro leaf). The wrapping is inedible ti leaves (Hawaiian: lau ki). Cooked taro leaf has the consistency of cooked spinach and is therefore unsuitable for use as a wrapping.
Samoa
In Samoa the baby talo leaves and coconut milk are wrapped into parcels and cooked, along with other food, in an umu. The parcels are called palusami or lu'au. The resulting taste is smoky, sweet, savoury and has a unique creamy texture. The root is also baked (Talo tao) in the umu or boiled with coconut cream (Faálifu Talo). It has a slightly bland and starchy flavor. It is sometimes called the Polynesian potato.
Sri Lanka
Many varieties are recorded in Sri Lanka, several being edible, others being toxic to humans and therefore not cultivated. Edible varieties (kiri ala, kolakana ala, gahala, sevel ala) are cultivated for their corms and leaves. Sri Lankans eat corms after boiling them or making them into a curry with coconut milk. The leaves of only one variety (kolakana ala) are eaten.
Suriname
In Suriname, the taro root is called aroei by the native Indians and is commonly known as "Chinese tayer". The variety known as "eddoe" is also called Chinese tayer. It is a popular cultivar among the marroon population in the interior, also because it is not adversely affected by high water levels. The "dasheen" variety, commonly planted in swamps, is rare, although appreciated for its taste. The closely related Xanthosoma species is the base for the popular Surinamese dish, pom.
Thailand
In Thai cuisine, taro Thai: ????? (pheuak) is used in a variety of ways depending on the region. Boiled taro is readily available in the market packaged in small cellophane bags, already peeled and diced, and eaten as a snack. Pieces of boiled taro with coconut milk are a traditional Thai dessert. Raw taro is also often sliced and deep fried and sold in bags as chips (????????). As in other Asian countries, taro is a popular flavor for ice cream in Thailand.
Tonga

Trinidad & Tobago
The leaves of the taro plant are used to make the Trinidadian variant of the Caribbean dish known as callaloo (which is made with okra, dasheen/taro leaves, coconut milk or creme and aromatic herbs) and it is also prepared similarly to steamed spinach. The root of the taro plant is often served boiled, accompanied by stewed fish or meat, curried, often with peas and eaten with roti, or in soups.
Turkey
Taro Turkish: Gölevez is grown in the south coast of Turkey, especially in Mersin, Bozyaz?, Anamur and Antalya. It is boiled in a tomato sauce or cooked with meat, beans and chickpeas. Often used to substitute Potato.
United States Mainland
In American Chinatowns, people often use taro in Chinese cuisine, though it is not as popular as in Asian and Pacific nations. Since the late 20th century, taro chips have been available in many supermarkets and natural food stores. In the 1920s, dasheen, as it was known, was highly touted by the Secretary of the Florida Department of Agriculture as a valuable crop for growth in muck fields. Fellsmere, Florida, near the east coast, was a farming area deemed perfect for growing dasheen. It was used in place of potatoes and dried to make flour. Dasheen flour was said to make excellent pancakes when mixed with wheat flour.
Venezuela
In Venezuela, taro is called ocumo chino or "chino" and used in soups and sancochos. Soups contain large chunks of several kinds of tubers, including ocumo chino, especially in the eastern part of the country, where West Indian influence is present. It is also used to accompany meats in "parrillas" (barbecue) or fried cured fish where yuca is not available. "Ocumo" is an indigenous name, and "chino" means Chinese, since people tend to give the "chinese" adjective to any produce that is considered "exotic". "Ocumo" without the Chinese denomination is a tuber from the same family, but without taro's inside purplish color. Ocumo is the Venezuelan name for malanga, so "ocumo chino" means "chinese malanga". Taro is always prepared boiled. No porridge form is known in the local cuisine.
Vietnam
In Vietnam, there is a large variety of taro plants. One is called Khoai môn, which is used as a filling in spring rolls, cakes, puddings and sweet soup desserts, smoothies and other desserts. Taro is used in the T?t dessert chè khoai môn which is sticky rice pudding with taro roots. The stems are also used in soups such as canh chua. One is called Khoai s?, which is smaller in size and more delicious than Khoai môn, and of course, more expensive than Khoai môn. Another more popular taro plants the roots grow in shallow waters and the stems and leaves above the surface of the water. This taro plants have saponins-like substances that make the endurable feeling of hot and itch in the mouth and throat. Northern farmers used to plant them to cook the stems and leaves to feed their hogs for their high speed of re-growth from their roots. After the cooking, the saponins in the soup of taro stems and leaves reduce to the level the trained hogs can eat. Nowadays, this practice is no longer widely popular in Vietnam agriculture. These taro plants are commonly called as khoai ng?a which literally means itchy potato.
West Africa
Taro is consumed as a staple crop in West Africa, particularly in Ghana, Nigeria and Cameroon. It is called cocoyam in Nigeria, Ghana and Anglophone Cameroon, and macabo in Francophone Cameroon. "Ede" in Igbo language .Cocoyam is often boiled, fried, or roasted and eaten with a sauce. In Ghana, it substitutes for plantain in making fufu when plantains are out of season. It is also cut into small pieces to make a soupy baby food and appetizer called mpotompoto. It is also common in Ghana to find cocoyam chips (deep-fried slices, about 1 mm thick). Cocoyam leaves, locally called kontomire in Ghana, are a popular vegetable for local sauces such as palaver sauce and egusi/agushi stew. It is also commonly consumed in Guinea and parts of Senegal, as a leaf sauce or as a vegetable side, and is referred to as jaabere in the local Pulaar dialect.
West Indies
Taro is called dasheen, in contrast to the smaller variety of corms called eddo, or tanya in the English speaking countries of the West Indies, and is cultivated and consumed as a staple crop in the region. There are differences amongst the roots mentioned above: taro or dasheen is mostly blue when cooked, tanya is white and very dry, and eddoes are small and very slimy.
In the Spanish speaking countries of the Spanish West Indies taro is called ñame, the Portuguese variant of which (inhame) is used in former Portuguese colonies where taro is still cultivated, including the Azores and Brazil. In Puerto Rico and Cuba, and the Dominican Republic it is sometimes called malanga or yautia. In some countries, such as Trinidad and Tobago, Saint Vincent and the Grenadines, and Dominica, the leaves and stem of the dasheen, or taro, are most often cooked and pureed into a thick liquid called callaloo, which is served as a side dish similar to creamed spinach. Callaloo is sometimes prepared with crab legs, coconut milk, pumpkin and okra. It is usually served alongside rice or made into a soup along with various other roots.
Toxicity
Taro contains oxalic acid which forms raphides. It is reduced to safe levels by steeping cubed taro roots in cold water overnight and disposing of the water. Calcium oxalate is highly insoluble and contributes to kidney stones. It has been recommended to avoid consuming calcium-rich foods like milk together with taro.
Similar plants
Similar taro variety is known as eddoe or Colocasia antiquorum. Other species of taro include giant taro (Alocasia macrorrhizos), swamp taro (Cyrtosperma merkusii), and arrowleaf elephant's ear (Xanthosoma sagittifolium).
