Taro ( ), also called Dasheen, and one of several plants called Cocoyam ,is a tropical plant grown primarily as a vegetable food for its edible corm, and secondarily as a leaf vegetable. It is considered a staple in Oceanic cultures. It is believed to be one of the earliest cultivated plants. In its raw form the plant is toxic due to the presence of calcium oxalate, although the toxin is destroyed by cooking or can be removed by steeping taro roots in cold water overnight. Taro is closely related to Xanthosoma and Caladium, plants commonly grown as ornamentals, and like them it is sometimes loosely called elephant ear. The name "taro" is from Tahitian or other Polynesian languages; the plant is also called kalo (from Hawaiian), gabi in The Philippinesmarker, dalo in Fijimarker, seppankizhangu in Tamil, chembu in Malayalam Arvee in Hindi, kochu in Bengali and Karkalo in Nepali.

Names and origin

Taro was probably first native to the lowland wetlands of Indonesiamarker where it was known as "talas." Estimates are that taro was in cultivation in wet tropical Indiamarker before 5000 B.C., presumably coming from Malaysia, and from India further transported westward to ancient Egyptmarker, where it was described by Greek and Roman historians as an important crop. The Indonesian crop and the indigenous name ("talas") followed prehistoric Austronesian seafarers into Oceania where it is currently known as cognate variants of "talas" including "dalo," "talo," "taro," and "kalo."

The scientific name for the species that includes Taro is Colocasia esculenta; esculent is an English word taken directly from Latin and means edible. The Xanthosoma genus is closely related, and several common names including callaloo and coco or cocoyam are used to refer to either Taro or domesticated Xanthosoma species which share substantially the same uses. Taro may be distinguished as "taro cocoyam" or "old cocoyam", with the term "new cocoyam" referring to species of Xanthosoma.

In Kenyamarker, taro root is referred to as arrow root, or by the Kikuyu or Kamba word ndŭma. In the Maldivesmarker this root or yam is referred as Ala. Varieties that grows in muddy ponds are called Olhu Ala . Olhu means a muddy pond. In South Africa, it referred to by the Zulu word amaDumbe or the anglicised madumbi. In some Caribbeanmarker countries, it is sometimes known as dasheen, a name said to be derived from the French de Chine which means from China and evokes the plant's Asian origins. The leaves are used to make a soup popular in the West Indiesmarker, called callaloo soup. In Cyprusmarker it is known as kolokassi, which is similar to the name the Romans used: colocasia, and it is known as "Qolqass" in Egypt. In Lebanonmarker it is known as kilkass. Taro is also known as dalo In the Fijian Islandsmarker and in Japan as satoimo.

Eddoe is another name that is sometimes used to designate small corm varieties of Taro, but more usually is reserved for an upland variety of C. esculenta that grows in drier soil.



Taro was used by the early Romans in much the same way the potato would later be used by Europeans. They called this root vegetable colocasia.Apicius mentions several methods for preparing taro. The text of Apicius seems to imply that the usual cooking method was to boil taro in water. Apicius suggests that a sauce be made from pepper, cumin, rue, vinegar, oil and liquamen to be served with chopped pieces of boiled taro. Apicius also mentions recipes in which pieces of taro are cooked along with meat or fowl, similar to the manner in which potatoes are now used in European meat dishes. After the fall of the Roman Empire, the use of taro gradually ceased in Europe. This was largely due to the decline of trade and commerce, as most of the taro used throughout the Roman Empire had been grown and exported from Egypt.

The small round variety is peeled and boiled, sold either frozen, bagged in its own liquids, or canned. The plant is actually inedible when raw because of needle-shaped raphides (calcium oxalate) in the plant cells.

Typical of leaf vegetables, taro leaves are rich in vitamins and mineral. They are a good source of thiamin, riboflavin, iron, phosphorus, and zinc, and a very good source of vitamin B6, vitamin C, niacin, potassium, copper, and manganese. Taro corms are very high in starch, and are a good source of dietary fiber. Oxalic acid may be present in the corm and especially in the leaf, and these foods should be eaten with milk or other foods rich in calcium in order to remove the oxalate in the digestive tract. Absorbing a large quantity of the oxalate ion into the blood stream poses health risks, especially for people with kidney disorders, gout, or rheumatoid arthritis. Calcium in the body reacts with the oxalate to form calcium oxalate, which is highly insoluble and is suspected to cause kidney stones.


In Bangladesh it is known as mukhi kochu. It is cooked with small prawns into a thick curry.


In Brazil the root is known as inhame. It is often prepared like the potato: boiled, mashed, or stewed.It is considered a health food, good for the immune system, particularly as a preventative againstmalaria, yellow fever and dengue.

Taro (called yutou, 芋头 or yunai, 芋艿 in China; 芋頭, wuh táu? in Hong Kong) is commonly used within Chinese cuisine in a variety of styles, mainly as a flavor enhancing ingredient. 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 is also woven to form a seafood birdsnest. The taro cake is also a delicacy traditionally eaten during the Chinese New Year. In desserts it is used in tong sui, bubble tea, as a flavoring in ice cream and other desserts in the China(f. ex. Sweet Taro Pie). McDonald's sells Taro flavored pies at their stores in China.


In Cyprus, taro has been in use since the time of the Roman Empire. Today it is known as "kolokassi" which is similar to the name the Romans used: colocasia. It is usually stewed with celery (and sometimes meat) in a tomato sauce. Taro also grows on Ikariamarker island; Ikarians credit the taro for saving them from famine during World War II.


Excavated Japanese satoimo root (stems are cut before the plant is dug up): (1) Remaining stem from parent or seed satoimo, (2) Parent or seed satoimo, (3) Remaining stem from child satoimo, (4) Child satoimo, (5) Grandchild satoimo
In Japanmarker, it is called , (kanji: 里芋) "village potato". The "child" and "grandchild" corms which bud from the parent satoimo, are called . Satoimo is has been propagated in Southeast Asia since the late Jōmon period. It was a regional staple food before rice became predominant.

The tuber, satoimo, is often prepared through simmering, but occasionally grated and eaten raw or steamed. The stalk, zuiki, can also be prepared a number of ways, depending on its variety.


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 2 ways: "Kilkass with lentils" which is a stew flavored with crushed garlic and lemon juice and "kilkass in tahini" (tahini is a sesame seed paste).


Ala was widely grown southern atolls, Addu, Fuvammulahmarker, Huvadhu, and Haddhunmathimarker, . They considered it a stable food even after rice was introduced. Ala and Olhu Ala is still widely eaten all over maldives. It is 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 also used to prepare varieties of sweets.


Taro is grown in the hilly regions of Nepalmarker. The modified stem (corm) of Taro is known as 'Pindalu' and petioles with leaves are known as 'Karkalo'. Almost all parts are eaten by making different dishes. Large leaves of Taro are use as an alternative to umbrella when unexpected rain occurs. Boiled corm of Taro is commonly served with salt, spices and chillies.It is popular among hill people. Chopped and dried leaf petioles are used to make cake called 'Maseura'.


In the Philippines, taro is called gabi. A popular rendition of the taro is Laing (pronounced /lah - ing/) which originates from the Bicol region in Southern Luzon. The dish's main ingredients are taro stem and leaf cooked in coconut milk, salted with fermented shrimp or fish bagoong. It is also heavily spiced with red hot chilies called sili'ng labuyo ("wild pepper")

Another dish where taro finds common use in the Filipino kitchen is the Philippine national stew, called sinigang. This sour stew may be made with pork and beef, shrimp, or fish. Peeled and diced taro is a basic ingredient of pork sinigang.

Finally, the third most common use of taro in the Filipino diet is in ginataan, literally meaning "cooked with coconut milk." This form of dessert, where coconut milk and taro are combined along with indigenous ingredients such as sago and jackfruit, is shared throughout most Southeast Asian cuisines.


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 methods 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 & Samoan "palusami" (wrapped coconut milk and onions), 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 with inedible ti leaves (Hawaiian: lau ki). The cooked taro leaf has the consistency of cooked spinach and would be unsuitable for use as a wrapping.

In the state of Maharashtra, it is called Alu in Marathi. The leaves, called 'Alu che Paana', are de-veined, rolled with a paste of gram flour, tamarind paste, red chilli powder, turmeric, coriander, asoefotida, salt and steamed. These can be cut into pieces, eaten as such 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 the Indian state of Gujaratmarker it is used to make patra, a dish with the leaves of the plant prepared with tamarind and other spices. Sindhis call it 'Kachaloo'; They fry it, smash it and re-fry it to make a dish called 'Took' which compliments Sindhi Curry.

In Keralamarker, a state in southern Indiamarker, taro corms are known as Chembu-kizhangu. It is used as a staple food, as a side dish, or as a component in various side dishes. As a staple food it is steamed, and eaten with a chutney of green pepper and shallot onions. The leaves and stems of certain varieties of taro are used as a vegetable in Kerala.

In other Indian states, Tamil Nadu & Andhra Pradeshmarker, taro corms are known as Sivapan-kizhangu 'chamagadda' or in coastal Andhra districts as 'Chaama dumpa' in Telugu, and can be cooked in many ways, deep fried in oil for a side item with rice, or cooked in a tangy tamarind sauce with spices, onion and tomato.

In Dakshin Kannada district in the state of Karnatakamarker, Taro is used in morning breakfast dish as Patrode.

In the Indian state of Uttarakhandmarker and neighbouring Nepalmarker, it is considered a health food with a variety of cooking styles. The most common style is boiling it in salty water in iron cooking pots until it becomes like porridge. Another style is to steam the young leaves called 'gava', sun-dry and then store it for later use. For another variety, the taro leaves and stems are used raw as an ingredient for pickles. The leaves and stems are mixed with black lentils and then dried as small balls called badi and used later on. The stems are also sun-dried and stored for later use. On one special day, women worship saptarshi (seven sages) and have rice with taro leaf vegetable only.

Care must be taken to oil one's hands before handling the leaves, as some leaves are acidic and cause scratching. The leaves are completely safe and delicious after cooking.

Taro is grown in the south coast of Turkey, especially in Mersin and Antalya. It is boiled in a tomato sauce or cooked with meat, beans and chickpeas.

United States

In Hawaiimarker, taro is a traditional staple, as in many tropical areas of the world, and is the base for making poi. In Chinatowns, people often use taro in Chinese cuisine, though it is not consumed or popularized nearly as much 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, Floridamarker, 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. In areas with large Spanish speaking communities (especially from of the Spanish West Indies like Puerto Rico, Cuba, Domican Republic,etc..) it is called ñame.


In Vietnam, where taro is called khoai môn, it is used as a filling in spring rolls, cakes, puddings, smoothies, soups and other desserts.

Taro can be grown in paddy fields or in upland situations where watering is supplied by rainfall or by supplemental irrigation. Some varieties of taro can also be grown away from the tropics.


Taro is usually grown in pondfields known as lo i in Hawaiian. The picture below shows several small lo i in Maunawili Valleymarker on Oahumarker. The ditch on the left in the picture is called an auwai and supplies diverted stream water to the 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 sometimes just as an ornamental plant.

The Hawaii Agricultural Statistics Service puts the 10-year median production of taro in the Hawaiian Islands at about 6.1 million pounds (2,800 t; Viotti, 2004). However, 2003 taro production in Hawaii was only 5 million pounds (2,300 t), an all-time low (record keeping started in 1946). The previous low, reached in 1997, was 5.5 million pounds (2,500 t). Yet, 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 has driven down harvests from a high of 14.1 million pounds (6,400 t) in 1948. But more recently the decline has resulted from pests and diseases. A non-native apple snail (Pomacea canaliculata) is a major culprit in the current crop declines. Also, a plant rot disease, traced to a newly identified species of the fungal genus, Phytophthora, now plagues crops throughout the state. Although pesticides could control both pests to some extent, pesticide use in the pondfields is barred because of the clear opportunity for chemicals to quickly migrate into streams and then into the ocean.

In early April 2008, the Hawaiian House Agriculture Committee voted 9-3 to send a bill to the full house that would put a 5 year moratorium on genetic modification of taro in Hawaii. This moratorium would only apply to Hawaiian varieties of taro, thereby allowing genetic alteration of non-native species. This would include possible alteration to Chinese varieties, which are currently being grown in Hawaii, giving rise to an opportunity for cross-pollination.


Although taro has been a staple of the Fijian diet for centuries, its growth as a commercial 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 to the large Polynesian populations of New Zealand, Australia, and Los Angeles in the United States.

Almost 80% of Fiji's exported taro comes from the Island of Taveunimarker 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) have been putting in place internal quarantine restrictions to prevent spread of the taro beetles to Taveuni to protect the export industry there. To date farmers from Taveuni are exporting taro beetle damage free produce to major consumers overseas.

The SPC Land Resources Division has also been conducting research into how best to control this pest in Fiji as well as other countries like Vanuatu, Solomon Islands and Papua New Guinea.
