Cocos nucifera, the coconut palm, is a monocot perennial member of the Arecaceae (palm family), cultivated in tropical areas worldwide for its fruit and fiber. It has been extolled in songs, novels, and films, such as the Marx Brothers movie, Cocoanuts and The Coconut song (see YouTube clip and YouTube song). It is particularly important in Pacific islands, where it can be a primary source of food and a major cash crop.
The species has been cultivated since prehistoric times and is no longer found in the wild. Its progenitors are thought to have originated in the western Pacific region known as Malesia (the floristic region that includes the Malay Peninsula and archipelago, New Guinea, and the Bismarck Archipelago) and the southwest Pacific. It is now cultivated and sometimes naturalized across tropical and subtropical areas worldwide, where it often grows along coastal areas.
Coconut palms are medium-sized, solitary herbaceous plants. Although treelike in form, their trunks are composed not of wood, but of fibrous, stout, overlapping stems, and may grow to 25 m tall (80 feet), topped by a crown of pinnately compound leaves up to 4 meters (15 feet) long.
The coconut is known for its great versatility as seen in the many domestic, commercial, and industrial uses of its different parts. Coconuts are part of the daily diet of many people. Its endosperm is known as the edible "flesh" of the coconut; when dried it is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is a refreshing beverage and can be processed to create alcohol or blended with gums and whiteners to make a popular milk substitute. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. It also has cultural and religious significance in many societies that use it. As of 2009, coconut was grown commercially in 80 countries, with total production of 61 million tons; leading producers were the Philippines, Indonesia, and India.
Coconuts have been used in traditional medicine around the world to treat numerous ailments, ranging from sore throat, colds, and earaches to tuberculosis, tumors, and ulcers. Recent medical studies have found that coconut can have antibacterial, antifungal, antihelmintic, and antiviral properties, among other health benefits. Coconut oil was once avoided because it is composed of saturated fats, which were thought to raise cholesterol. However, recent research suggests that because it has medium- rather than long-chain fatty acids, coconut oil does not raise cholesterol, but may actually protect against heart disease. Coconut has now become popular as a health food, with numerous products and web sites extolling its benefits.
The term coconut can refer to the entire coconut palm, the seed, or the fruit, which is not technically a nut. The spelling cocoanut is an old-fashioned form of the word. The term is derived from 16th century Portuguese and Spanish “cocos,” meaning "grinning face," from the three small holes on the coconut shell that resemble human facial features.

Cocos nucifera is commonly known as a coconut palm and literally has hundreds of uses but is most well known for the products of its fruit, such as coconut meat, coconut water, coconut milk, and coconut oil. While the coconut palm is well known for many edible products it is also an important source of traditional medicine, crafting material and fuel (Morrison et al. 1994).
Almost all edible products of the coconut come from the fruit, or “nut” portion of the plant. The hard endosperm of the seed is edible when fresh but can also be dried and shredded to make desiccated coconut, a common topping for baked goods and sweets in the Europe and North America which is especially popular as a topping on bread, chocolate, cake and ice cream or frozen yogurt (Haynes and McLaughlin 2000).
The liquid endosperm of the immature fruit, often called "coconut water" is potable and readily consumable when fresh (Bennett 2007). It has nearly the same composition as many popular sports drinks that are marketed as “hydration aids” and has experience a recent explosion of commercial popularity in North America though it has been a common beverage in the tropics and subtropics for generations (Haynes and McLaughlin 2000). In the Philippines, it is the key ingredient for making the gelatinous dessert nata de coco and is also used to feed infants, as it is in many other countries. Coconut water is also used for medicinal purposes (Grimwood 1975).
Modern medicine has found that coconut water can be a good substitute for intravenous infusions, and it has been used to replace blood plasma in emergency surgery (Bennett 2007; Grimwood 1975). In Nigerian folk medicine, the coconut fruit products are prescribed as “anti-poison” treatments that are meant to neutralize toxic and venomous substances (Aiyeloja and Bello 2006). Whereas in traditional South Asian medicine, coconut water is sometimes mixed with “coconut milk,” to treat intestinal worms and other stomach problems. It is said to be particularly useful for dealing with cholera because the salines and albumins in it restrict vomiting and has further been reported to reduce rashes from small pox, chicken pox and measles (Grimwood 1975).
More edible products can be made by tapping the inflorescence of the plant for sap, which is called “tody” (Bennett 2007). Tody can then be boiled to produce coconut sugar which is known as “jaggery (Haynes and McLaughlin 2000).” If the tody is instead fermented, it can become the alcoholic beverage arrack, which in turn can become coconut vinegar if it is fermented for even longer (Haynes and McLaughlin 2000; Grimwood 1975). Additionally, coconut heart of palm can be harvested from any plant older than three years of age and used to make salads (Haynes and McLaughlin 2000).
Coconut milk and coconut cream are also products of the fruit however the terms “coconut milk” and “coconut cream” are not always distinct and can be used in different parts of the world to refer to the same product (Haynes and McLaughlin 2000). Coconut milk/cream is an emulsion of coconut oil and water achieved by shredding and squeezing the fresh coconut flesh from inside the nut and then adding coconut oil; alternately, a simpler version can be produced by grating the coconut with hot water (Grimwood 1975; Bennett 2007). These products, along with coconut oil, have no cholesterol and are readily digestible (Haynes and McLaughlin 2000). The coconut palm is also an important source of vegetable oil and fixed oil in the Americas among the three most important oil yielding palms (Haynes and McLaughlin 2000).
Coconut fruit provides many edible products to humans but is also often used as food for domestic animals in tropical countries, especially pigs, chickens and dogs, but is also used in industrial livestock and poultry operations as a component of animal feed (Morrison et al. 1994).
The shell of the fruit is also highly useful in and yields its own products. In addition to being used as cups, bowls, spoons, containers and other cooking equipment, the excess shells from coconut plantations are often used to build roads and also for lining wells during drilling (Morrison et al. 1994; Grimwood 1975). It is also the preferred portion of the plant to use for fuel (though all portions may be used for fuel) because it is an excellent source of coconut charcoal (Morrison et al. 1994). Coconut charcoal is produced industrially in the Caribbean, South Asia and the Pacific Islands and is a big source of fuel in many islands of the Pacific (Grimwood 1975; Morrison et al. 1994). Furthermore, ash from coconut shells are said to be good substitutes for potassium fertilizer and sample measurements from Malaysia show that they contain the equivalent of 52.2% potassium in ash form (Grimwood 1975).
In terms of yielding construction material, the husk fiber, known as coir is derived from the mesocarp fibers that surround the seed and is used to manufacture items like rope and twine, which are then used to lash together structures or for fishing nets and string fishing lines (Morrison et al. 1994). Coir can also be used as stuffing or caulking, or for weaving mats, skirts, hats and paint brushes (Bennett 2007, Morrison et al. 1994). The palm leaf can also be woven or used for split roof thatch but may also be woven to produce other products including baskets, purses, bags and hats (Bennett 2007).

Life History and Behavior
Evolution and Systematics
The seeds of coconut palms survive long sea voyages because they are enclosed in nutrient-rich, water-filled protective shells.
"Some trees send their seeds, not by air, but by sea. The most famous of all is the coconut palm. It dispatches its seed inside a hard shell that contains everything needed for a long voyage. Inside there is a supply of rich food, the so-called meat, and a half-a-pint or so of water. On the outside, it is fitted with a fibre float that keeps it on the surface of the water. This survival package serves it so well that coconut palms have colonised beaches throughout the tropics." (Attenborough 1995:21)

Comments: Liquid endosperm (coco milk) is drunk and the hard part of the endosperm is eaten, used in ice cream, for sweet coco pasta, and for dried coco flour. Minor uses include household articles, trinkets, and souvenirs which are made from the hard, bony endocarp and sold; the Cayapas indians in western Ecuador use immature fruits as a sterilizing remedy, crushing, boiling, and drinking a decoction of the husk twice daily during menstruation to stop the periods. On the market-place in Otavalo, Ecuador, the coconut husk is sold as a remedy against abdominal pains and small brooms are made from the leaf-base fibers; on Isla Puná it is used as a remedy against intestinal parasites and some kidney diseases and its leaves are used for thatch. This species is amply cultivated.
The coconut palm (Cocos nucifera), is a member of the family Arecaceae (palm family). It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from 16th-century Portuguese and Spanish coco, meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.
Found throughout the tropic and subtropic area, the coconut is known for its great versatility as seen in the many uses of its different parts. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is a refreshing drink. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. It also has cultural and religious significance in many societies that use it.

Cocos nucifera is a large palm, growing up to 30 m (98 ft) tall, with pinnate leaves 4–6 m (13–20 ft) long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. Coconuts are generally classified into two general types: tall and dwarf. On very fertile land, a tall coconut palm tree can yield up to 75 fruits per year, but more often yields less than 30, mainly due to poor cultural practices. In recent years, improvements in cultivation practices and breeding have produced coconut trees that can yield more.
Botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers: the exocarp, mesocarp, and endocarp. The exocarp and mesocarp make up the "husk" of the coconut. Coconuts sold in the shops of nontropical countries often have had the exocarp (outermost layer) removed. The mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores (stoma) or "eyes" that are clearly visible on its outside surface once the husk is removed.
The coconut palm root system consists of an abundance of thin roots that grow outward from the plant near the surface. Only a few of the roots penetrate deep into the soil for stability. The type of root system is known as fibrous or adventitious, and is a characteristic of grass species. Other types of large trees produce a single downward-growing tap root with a number of feeder roots growing from it.
Coconut palms continue to produce roots from the base of the stem throughout its life. The number of roots produced depends on the age of the tree and the environment, with more than 3,600 roots possible on a tree that's 60 to 70 years old.
Roots are usually less about 3 inches in diameter and uniformly thick from the tree trunk to the root tip.
The palm produces both the female and male flowers on the same inflorescence; thus, the palm is monoecious. Other sources use the term polygamomonoecious. The female flower is much larger than the male flower. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some[which?] dwarf varieties are self-pollinating.
One of the earliest mentions of the coconut dates back to the One Thousand and One Nights story of Sinbad the Sailor; he is known to have bought and sold coconuts during his fifth voyage. Tenga, its Malayalam name, was used in the detailed description of coconut found in Itinerario by Ludovico di Varthema published in 1510 and also in the later Hortus Indicus Malabaricus. Even earlier, it was called nux indica, a name used by Marco Polo in 1280 while in Sumatra, taken from the Arabs who called it جوز هندي jawz hindī. Both names translate to "Indian nut". In the earliest description of the coconut palm known, given by Cosmos of Alexandria in his Topographia Christiana written about 545 AD, there is a reference to the argell tree and its drupe.
Historical evidence favors the European origin of the name "coconut", for no name is similar in any of the languages of India, where the Portuguese first found the fruit; and indeed Barbosa, Barros, and Garcia, in mentioning the Malayalam name tenga, and Canarese narle, expressly say, "we call these fruits quoquos", "our people have given it the name of coco", and "that which we call coco, and the Malabars temga".
The OED states: "Portuguese and Spanish authors of the 16th c. agree in identifying the word with Portuguese and Spanish coco "grinning face, grin, grimace", also "bugbear, scarecrow", cognate with cocar "to grin, make a grimace"; the name being said to refer to the face-like appearance of the base of the shell, with its three holes. According to Losada, the name came from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The coconut shell reminded them of a ghost or witch in Portuguese folklore called coco (also côca). The first known recorded usage of the term is 1555.
The specific name nucifera is Latin for "nut-bearing".
Origin, domestication, and dispersal
The origin of the plant is the subject of debate. O.F. Cook was one of the earliest modern researchers to draw conclusions about the location of origin of Cocos nucifera based on its current-day worldwide distribution. He hypothesized that the coconut originated in the Americas, based on the fact that American coconut populations predated European contact and because he considered pan-tropical distribution by ocean currents improbable. Thor Heyerdahl later used this hypothesis of the American origin of the coconut to support his theory that the Pacific Islanders originated in South America. However, more evidence exists for an Indo-Pacific origin either around Melanesia and Malesia or the Indian Ocean. The oldest fossils known of the modern coconut dating from the Eocene period from around 37 to 55 million years ago were found in Australia and India. However, older palm fossils such as some of nipa fruit have been found in the Americas.
Since 1978, the work on tracing the probable trajectory of cultivation for Cocos nucifera has only recently been augmented by a publication on the germination rate of the coconut seednut  and another on the importance of the coral atoll ecosystem. Briefly, the coconut originated in the coral atoll ecosystem - without human intervention - and required a thick husk and slow germination to survive and disperse. Coconuts could NOT reach inland location without human intervention (to carry seednuts, plant seedlings, etc) and it was early germination on the palm (vivipary) that was important, rather than increasing the number or size of the edible parts of a fruit that was already large enough. Human cultivation of the coconut selected, not for larger size, but for thinner husks and increased volume of endosperm, the solid “meat” or liquid “water” that provides the fruit its food value. Although these modifications for domestication would reduce the fruit’s ability to float, this ability would be irrelevant to a cultivated population. Among modern C. nucifera, two major types or variants: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera: the first coconuts were of the niu kafa type, with thick husks to protect the seed, an angular, highly ridged shape to promote buoyancy during ocean dispersal, and a pointed base that allowed fruits to dig into the sand, preventing them from being washed away during germination on a new island. As early human communities began to harvest coconuts for eating and planting, they (perhaps unintentionally) selected for a larger endosperm to husk ratio and a broader, spherical base, which rendered the fruit useful as a cup or bowl, the creating the niu vai type. The decreased buoyancy and increased fragility of this spherical, thin-husked fruit would not matter for a species that had started to be dispersed by humans and grown in plantations. Harries’ adoption of the Polynesian terms niu kafa and niu vai has now passed into general scientific discourse, and his hypothesis is generally accepted.
Variants of C. nucifera are also categorized as Tall (var. typical) or Dwarf (var. nana). The two groups are genetically distinct, with the Dwarf variety showing a greater degree of artificial selection for ornamental traits and for early germination and fruiting. The Tall variety is outcrossing while Dwarf palms are incrossing, which has led to a much greater degree of genetic diversity within the Tall group. It is believed that the Dwarf subgroup mutated from the Tall group under human selection pressure.
It is often cited that coconuts can travel 110 days, or 3000 miles, by sea and still be able to germinate. This figure has been questioned based on the extremely small sample size of the paper that makes this claim. Thor Heyerdahl provides an alternative, and much shorter, estimate based on his first-hand experience crossing the Pacific Ocean on the raft Kon-Tiki: “The nuts we had in baskets on deck remained eatable and capable of germinating the whole way to Polynesia. But we had laid about half among the special provisions below deck, with the waves washing around them. Every single one of these was ruined by the sea water. And no coconut can float over the sea faster than a balsa raft moves with the wind behind it." He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, it is more than likely that the coconut variety Heyerdahl chose for his long sea voyage was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type. Therefore Heyerdahl’s observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.
Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided. This provides some circumstantial evidence that Austronesian peoples carried coconuts across the ocean and that they could not have dispersed worldwide without human agency. More recently, genomic analysis of cultivated coconut (Cocos nucifera L.) has shed light on the movements of Austronesian peoples. By examining 10 microsatelite loci, researchers found two genetically distinct subpopulations of coconut—one originating in the Indian Ocean, the other in the Pacific Ocean. However, admixture, the transfer of genetic material, evidently occurred between the two populations. Given that coconuts are ideally suited for ocean dispersal, individuals from one population possibly could have floated to the other. However, the locations of the admixture events are limited to Madagascar and coastal east Africa, and exclude the Seychelles. This pattern coincides with the known trade routes of Austronesian sailors. Additionally, a genetically distinct subpopulation of coconut on the Pacific coast of Latin America has undergone a genetic bottleneck resulting from a founder effect; however, its ancestral population is the Pacific coconut, which suggests Austronesian peoples may have sailed as far east as the Americas.
The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild are light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents. Specimens have been collected from the sea as far north as Norway. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years, but evidence of their presence on the Pacific coast of South America predates Christopher Columbus's arrival in the Americas. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America.
The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually), which makes colonizing shorelines of the tropics relatively straightforward. Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity, like the southeastern Mediterranean or Andalusia, even where temperatures are high enough (regularly above 24 °C or 75.2 °F).
Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Optimum growth is with a mean annual temperature of 27 °C (81 °F), and growth is reduced below 21 °C (70 °F). Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28 and 37 °C (82 and 99 °F), and survival as long as winter temperatures are above 4–12 °C (39–54 °F); they will survive brief drops to 0 °C (32 °F). Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C (25 °F). They may grow but not fruit properly in areas with insufficient warmth, such as Bermuda.
The conditions required for coconut trees to grow without any care are:
- Mean daily temperature above 12–13 °C (53.6–55.4 °F) every day of the year
- Mean annual rainfall above 1,000 mm (39.37 in)
- No or very little overhead canopy, since even small trees require direct sun
The main limiting factor for most locations which satisfy the rainfall and temperature requirements is canopy growth, except those locations near coastlines, where the sandy soil and salt spray limit the growth of most other trees.
The coconut palm is damaged by the larvae of many Lepidoptera (butterfly and moth) species which feed on it, including Batrachedra spp.: B. arenosella, B. atriloqua (feeds exclusively on C. nucifera), B. mathesoni (feeds exclusively on C. nucifera), and B. nuciferae.
Brontispa longissima (coconut leaf beetle) feeds on young leaves, and damages seedlings and mature coconut palms. In 2007, the Philippines imposed a quarantine in Metro Manila and 26 provinces to stop the spread of the pest and protect the $800 million Philippine coconut industry.
The fruit may also be damaged by eriophyid coconut mites (Eriophyes guerreronis). This mite infests coconut plantations, and is devastating: it can destroy up to 90% of coconut production. The immature seeds are infested and desapped by larvae staying in the portion covered by the perianth of the immature seed; the seeds then drop off or survive deformed. Spraying with wettable sulfur 0.4% or with neem-based pesticides can give some relief, but is cumbersome and labor intensive.
In Kerala, the main coconut pests are the coconut mite, the rhinoceros beetle, the red palm weevil and the coconut leaf caterpillar. Research on this topic has as of 2009[update] produced no results, and researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode are still searching for a cure. The Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called compact area group approach (CAGA) to combat coconut mites.

Coconut palms are grown in more than 80 countries of the world, with a total production of 61 million tonnes per year. Coconut trees are very hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.
In some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand, and in the Malaysian state of Kelantan. Competitions are held each year to find the fastest harvester.
Traditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Puducherry, Andhra Pradesh, Karnataka, Goa, Maharashtra, Odisha, West Bengal and the islands of Lakshadweep and Andaman and Nicobar. Four southern states combined account for almost 92% of the total production in the country: Kerala (45.22%), Tamil Nadu (26.56%), Karnataka (10.85%), and Andhra Pradesh (8.93%). Other states, such as Goa, Maharashtra, Odisha, West Bengal, and those in the northeast (Tripura and Assam) account for the remaining 8.44%. Kerala, which has the largest number of coconut trees, is famous for its coconut-based products—coconut water, copra, coconut oil, coconut cake (also called coconut meal, copra cake, or copra meal), coconut toddy, coconut shell-based products, coconut wood-based products, coconut leaves, and coir pith.
Various terms, such as copra and coir, are derived from the native Malayalam language. In Kerala, the coconut tree is called "Thengu" also termed as kalpa vriksham, which essentially means all parts of a coconut tree is useful some way or other.
The coconut is the national tree of the Maldives and is considered the most important plant in the country. A coconut tree is also included in the country's national emblem or coat of arms. Coconut trees are grown on all the islands. Before modern construction methods were introduced, coconut leaves were used as roofing material for many houses in the islands, while coconut timber was used to build houses and boats.
The main coconut-producing area in the Middle East is the Dhofar region of Oman, but they can be grown all along the Persian Gulf, Arabian Sea and Red Sea coasts, because these seas are tropical and provide enough humidity (through seawater evaporation) for coconut trees to grow. The young coconut plants need to be nursed and irrigated with drip pipes until they are old enough (stem bulb development) to be irrigated with brackish water or seawater alone, after which they can be replanted on the beaches. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea in Kerala. The reasons why coconut are cultivated only in Yemen's Al Mahrah and Hadramaut governorates and in the Sultanate of Oman, but not in other suitable areas in the Arabian Peninsula, may originate from the fact that Oman and Hadramaut had long dhow trade relations with Burma, Malaysia, Indonesia, East Africa and Zanzibar, as well as southern India and China. Omani people needed the coir rope from the coconut fiber to stitch together their traditional high seas-going dhow vessels in which nails were never used. The 'know how' of coconut cultivation and necessary soil fixation and irrigation may have found its way into Omani, Hadrami and Al-Mahra culture by people who returned from those overseas areas.
The coconut cultivars grown in Oman are generally of the drought-resistant Indian "West Coast tall" (WC Tall) variety. Unlike the UAE, which grows mostly non-native dwarf or hybrid coconut cultivars imported from Florida for ornamental purposes, the slender, tall Omani coconut cultivars are relatively well-adapted to the Middle East's hot dry seasons, but need longer to reach maturity. The Middle East's hot, dry climate favors the development of coconut mites, which cause immature seed dropping and may cause brownish-gray discoloration on the coconut's outer green fiber.
The ancient coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla. The annual rainy season known locally as Khareef or monsoon makes coconut cultivation easy on the Arabian east coast.
Coconut trees also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE has, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, as the mixing of date and coconut trees poses a risk of cross-species palm pests, such as rhinoceros beetles and red palm weevils. The artificial landscaping adopted in Florida may have been the cause for lethal yellowing, a viral coconut palm disease that leads to the death of the tree. It is spread by host insects, that thrive on heavy turf grasses. Therefore, heavy turf grass environments (beach resorts and golf courses) also pose a major threat to local coconut trees. Traditionally, dessert banana plants and local wild beach flora such as Scaevola taccada and Ipomoea pes-caprae were used as humidity-supplying green undergrowth for coconut trees, mixed with sea almond and sea hibiscus. Due to growing sedentary life styles and heavy-handed landscaping, there has been a decline in these traditional farming and soil-fixing techniques.
An early mention of the planting of coconuts is found in the Mahavamsa during the reign of Agrabodhi II around 589 AD. Coconuts are common in the Sri Lankan diet and the main source of dietary fat. Sri Lanka is home to the Coconut Research Institute of Sri Lanka.
The only places in the United States where coconut palms can be grown and reproduced outdoors without irrigation are Hawaii, southern Florida, and the territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands.
Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in the Tampa and Clearwater metro areas and around Cape Canaveral, as well as the Orlando-Kissimmee-Daytona Beach metro area. They may likewise be grown in favoured microclimates in the Rio Grande Valley area of southern Texas near Brownsville, along the upper northeast coast of by Galveston Island, and in the Southern California coast, specifically Newport Beach, California. They may reach fruiting maturity, but are damaged or killed by the occasional winter freezes in these areas. While coconut palms flourish in southern Florida, rare cold snaps can injure coconut palms there, as well. Only the Florida Keys and the distant southern Atlantic coastlines provide safe havens from the cold for growing coconut palms on the mainland.
Coconuts are commonly grown around the northern coast of Australia, and in some warmer parts of New South Wales.
Most of the tall mature coconut trees found in Bermuda were shipped to the island as seedlings on the decks of ships. In more recent years, the importation of coconuts was prohibited, therefore, a large proportion of the younger trees have been propagated from locally grown coconuts.
In the winter months, the growth rate of coconut trees declines due to cooler temperatures and people have commonly attributed this to the reduced yield of coconuts in comparison to tropical regions. However, whilst cooler winter temperatures may be a factor in reducing fruit production, the primary reason for the reduced yield is a lack of water. Bermuda's soil is generally very shallow (1.5 to 3 feet) and much of a coconut tree's root mass is found in the porous limestone underneath the soil. Due to the porosity of the limestone, Bermuda's coconut trees do not generally have a sufficient supply of water with which they are able to support a large number of fruit as rain water quickly drains down through the limestone layer to the water table which is far too deep for a coconut's roots to reach. This typically leads to a reduction in fruit yield (sometimes as little as one or two mature fruits) as well as a reduced milk content inside the coconut that often causes the fruit to be infertile.
Conversely, trees growing in close proximity to the sea almost universally yield a much greater volume of fruit as they are able to tap directly into the sea water which permeates the limestone in such areas. Not only do these trees produce a significantly higher yield, but also the fruit itself tends to be far more fertile due to the higher milk content. Trees found growing in Bermuda's marshy inland areas enjoy a similar degree of success as they are also able to tap directly into a constant supply of water.
In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana), is used in landscaping. Its fruits are very similar to the coconut, but much smaller. The queen palm was originally classified in the genus Cocos along with the coconut, but was later reclassified in Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar, is nearly identical to the coconut, more so than the queen palm and can also be grown in slightly cooler climates than the coconut palm. Coconuts can only be grown in temperatures above 18 °C (64 °F), but need a daily temperature above 22 °C (72 °F) to produce fruit.
Overview of uses
The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and nonculinary uses; virtually every part of the coconut palm can be used by humans in some manner and has significant economic value. Coconuts' versatility is sometimes noted in its naming. In Sanskrit, it is kalpa vriksha ("the tree which provides all the necessities of life"). In the Malay language, it is pokok seribu guna ("the tree of a thousand uses"). In the Philippines, the coconut is commonly called the "tree of life".
The various parts of the coconut have a number of culinary uses. The seed provides oil for frying, cooking, and making margarine. The white, fleshy part of the seed, the coconut meat, is used fresh or dried in cooking, especially in confections and desserts such as macaroons. Desiccated coconut or coconut milk made from it is frequently added to curries and other savory dishes. Coconut flour has also been developed for use in baking, to combat malnutrition. Coconut chips have been sold in the tourist regions of Hawaii and the Caribbean. Coconut butter is often used to describe solidified coconut oil, but has also been adopted as a name by certain specialty products made of coconut milk solids or puréed coconut meat and oil. Dried coconut is also used as the filling for many chocolate bars. Some dried coconut is purely coconut but others are manufactured with other ingredients, such as sugar, propylene glycol, salt, and sodium metabisulfite.

Coconut water serves as a suspension for the endosperm of the coconut during its nuclear phase of development. Later, the endosperm matures and deposits onto the coconut rind during the cellular phase. Coconut water contains sugar, dietary fiber, proteins, antioxidants, vitamins, and minerals, and provides an isotonic electrolyte balance. It is consumed as a refreshing drink throughout the humid tropics, and is gaining popularity as a sports drink. Mature fruits have significantly less liquid than young, immature coconuts, barring spoilage. Coconut water can be fermented to produce coconut vinegar.

Coconut milk, not to be confused with coconut water, is obtained primarily by extracting juice by pressing the grated coconut's white kernel or by passing hot water or milk through grated coconut, which extracts the oil and aromatic compounds. It has a fat content around 17%. When refrigerated and left to set, coconut cream will rise to the top and separate from the milk. The milk can be used to produce virgin coconut oil by controlled heating and removal of the oil fraction.
Another byproduct of the coconut is coconut oil. It is commonly used in cooking, especially for frying. It can be used in liquid form as would other vegetable oils, or in solid form as would butter or lard.
Toddy and nectar
The sap derived from incising the flower clusters of the coconut is drunk as neera, also known as toddy or tuba (Philippines), tuak (Indonesia and Malaysia) or karewe (fresh and not fermented, collected twice a day, for breakfast and dinner) in Kiribati. When left to ferment on its own, it becomes palm wine. Palm wine is distilled to produce arrack. In the Philippines, this alcoholic drink is called lambanog or "coconut vodka".
The sap can be reduced by boiling to create a sweet syrup or candy such as te kamamai in Kiribati or dhiyaa hakuru and addu bondi in the Maldives. It can be reduced further to yield coconut sugar also referred to as palm sugar or jaggery. A young, well-maintained tree can produce around 300 liters (66 imp gal; 79 U.S. gal) of toddy per year, while a 40-year-old tree may yield around 400 liters (88 imp gal; 110 U.S. gal).
Heart of palm and coconut sprout
Apical buds of adult plants are edible, and are known as "palm cabbage" or heart of palm. They are considered a rare delicacy, as harvesting the buds kills the palms. Hearts of palm are eaten in salads, sometimes called "millionaire's salad". Newly germinated coconuts contain an edible fluff of marshmallow-like consistency called coconut sprout, produced as the endosperm nourishes the developing embryo.
In 2010, Indonesia increased its coconut production. It is now the world's second largest producer of coconuts. The gross production was 15 million tonnes. A sprouting coconut seed is the logo for Gerakan Pramuka Indonesia, the Indonesian Scouting organization. It can be seen on all the scouting paraphernalia that elementary (SMA) school children wear as well as on the scouting pins and flags.
The Philippines is the world's largest producer of coconuts, the production of coconuts plays an important role in the economy. Coconuts in the Philippines are usually used in making main dishes, refreshments and desserts. Coconut juice is also a popular drink in the country. In the Philippines, particularly Cebu, rice is wrapped in coconut leaves for cooking and subsequent storage; these packets are called puso. Coconut milk, known as gata, and grated coconut flakes are used in the preparation of dishes such as laing, ginataan, bibingka, ube halaya, pitsi-pitsi, palitaw, buko pie and more. Coconut jam is made by mixing muscovado sugar with coconut milk. Coconut sport fruits are also harvested. One such variety of coconut is known as macapuno. Its meat is sweetened, cut into strands and sold in glass jars as coconut strings, sometimes labeled as "gelatinous mutant coconut". Coconut water can be fermented to make a different product—nata de coco (coconut gel).
In Vietnam, coconut is grown mainly in Bến Tre Province, often called the "land of the coconut". It is used to make coconut candy, caramel, and jelly. Coconut juice and coconut milk are used, especially in Vietnam's southern style of cooking, including kho and chè.
In southern India, most common way of cooking vegetables is to add grated coconut and then steam them with spices fried in oil. People from southern India also make chutney, which involves grinding the coconut with salt, chillies, and whole spices. Uruttu chammanthi (granulated chutney) is eaten with rice or kanji (rice gruel). It is also invariably the main side dish served with idli, vadai, and dosai. Coconut ground with spices is also mixed in sambar and other various lunch dishes for extra taste. Dishes garnished with grated coconut are generally referred to as poduthol in North Malabar and thoran in rest of Kerala. Puttu is a culinary delicacy of Kerala and Tamil Nadu, in which layers of coconut alternate with layers of powdered rice, all of which fit into a bamboo stalk. Recently, this has been replaced with a steel or aluminium tube, which is then steamed over a pot. Coconut (Tamil: தேங்காய்) is regularly broken in the middle-class families in Tamil Nadu for food. Coconut meat can be eaten as a snack sweetened with jaggery or molasses. In Karnataka sweets are prepared using coconut and dry coconut "copra"., Like Kaie Obattu, Kobri mitai etc.
Commercial, industrial, and household use
Coconut has a number of commercial and traditional cultivars. They can be sorted mainly into tall cultivars, dwarf cultivars and hybrid cultivars (hybrids between talls and dwarfs). Some of the dwarf cultivars such as Malayan dwarf has shown some promising resistance to lethal yellowing while other cultivars such as Panama tall is highly affected by the same plant disease. Some cultivars are more drought resistant such as West coast tall (India) while others such as Hainan Tall (China) are more cold tolerant. Other aspects such as seed size, shape and weight and copra thickness are also important factors in the selection of new cultivars. Some cultivars such as Fiji dwarf form a large bulb at the lower stem and others are cultivated to produce very sweet coconut water with orange coloured husks (king coconut) used entirely in fruit stalls for drinking (Sri Lanka, India).
Coir (the fiber from the husk of the coconut) is used in ropes, mats, door mats, brushes, sacks, caulking for boats, and as stuffing fiber for mattresses. It is used in horticulture in potting compost, especially in orchid mix.
The stiff mid-ribs of coconut leaves are used for making brooms in India, Indonesia (sapu lidi), Malaysia, the Maldives and the Philippines (walis tingting). The green of the leaves (lamina) are stripped away, leaving the veins (wood-like, thin, long strips) which are tied together to form a broom or brush. A long handle made from some other wood may be inserted into the base of the bundle and used as a two-handed broom. The leaves also provide material for baskets that can draw well water and for roofing thatch; they can be woven into mats, cooking skewers, and kindling arrows, as well. Two leaves (especially the younger, yellowish shoots) woven into a tight shell the size of the palm are filled with rice and cooked to make ketupat. Dried coconut leaves can be burned to ash, which can be harvested for lime. In India, the woven coconut leaves are used as pandals (temporary sheds) for marriage functions especially in the states of Kerala, Karnataka, and Tamil Nadu.
Copra is the dried meat of the seed and after processing produces coconut oil and coconut meal. Coconut oil, aside from being used in cooking as an ingredient and for frying, is used in soaps, cosmetics, hair-oil, and massage oil. Coconut oil is also a main ingredient in Ayurvedic oils. In Vanuatu coconut palms for copra production are generally spaced 9 meters apart, allowing a tree density of 100–160 trees per hectare.
Husks and shells
The husk and shells can be used for fuel and are a source of charcoal. Activated carbon manufactured from coconut shell is considered extremely effective for the removal of impurities. The coconut's obscure origin in foreign lands led to the notion of using cups made from the shell to neutralise poisoned drinks. The cups were frequently engraved and decorated with precious metals.
A dried half coconut shell with husk can be used to buff floors. It is known as a bunot in the Philippines and simply a "coconut brush" in Jamaica. The fresh husk of a brown coconut may serve as a dish sponge or body sponge. Tempurung as the shell is called in the Malay language can be used as a soup bowl and—if fixed with a handle—a ladle. In India, coconut shells are also used as bowls and in the manufacture of various handicrafts, including buttons carved from dried shell. Coconut buttons are often used for Hawaiian aloha shirts. In Thailand, the coconut husk is used as a potting medium to produce healthy forest tree saplings. The process of husk extraction from the coir bypasses the retting process, using a custom-built coconut husk extractor designed by ASEAN–Canada Forest Tree Seed Centre (ACFTSC) in 1986. Fresh husks contains more tannin than old husks. Tannin produces negative effects on sapling growth. In parts of South India, the shell and husk are burned for smoke to repel mosquitoes.
Half coconut shells are used in theatre Foley sound effects work, banged together to create the sound effect of a horse's hoofbeats. Dried half shells are used as the bodies of musical instruments, including the Chinese yehu and banhu, along with the Vietnamese đàn gáo and Arabo-Turkic rebab. In the Philippines, dried half shells are also used as a music instrument in a folk dance called maglalatik.
In World War II, coastwatcher scout Biuki Gasa was the first of two from the Solomon Islands to reach the shipwrecked and wounded crew of Motor Torpedo Boat PT-109 commanded by future U.S. president John F. Kennedy. Gasa suggested, for lack of paper, delivering by dugout canoe a message inscribed on a husked coconut shell. This coconut was later kept on the president's desk, and is now in the John F. Kennedy Library.
Coconut trunks are used for building small bridges and huts; they are preferred for their straightness, strength, and salt resistance. In Kerala, coconut trunks are used for house construction. Coconut timber comes from the trunk, and is increasingly being used as an ecologically sound substitute for endangered hardwoods. It has applications in furniture and specialized construction, as notably demonstrated in Manila's Coconut Palace.
Hawaiians hollowed the trunk to form drums, containers, or small canoes. The "branches" (leaf petioles) are strong and flexible enough to make a switch. The use of coconut branches in corporal punishment was revived in the Gilbertese community on Choiseul in the Solomon Islands in 2005.
Use in beauty products
Coconuts are used in the beauty industry in moisturisers and body butters because coconut oil, due to its chemical structure, is readily absorbed by the skin. The coconut shell may also be ground down and added to products for exfoliation of dead skin. Coconut is also a source of lauric acid, which can be processed in a particular way to produce sodium lauryl sulfate, a detergent used in shower gels and shampoos. The nature of lauric acid as a fatty acid makes it particularly effective for creating detergents and surfactants.
Role in culture and religion
In the Ilocos region of northern Philippines, the Ilocano people fill two halved coconut shells with diket (cooked sweet rice), and place liningta nga itlog (halved boiled egg) on top of it. This ritual, known as niniyogan, is an offering made to the deceased and one's ancestors. This accompanies the palagip (prayer to the dead).
A coconut (Sanskrit: narikela) is an essential element of rituals in Hindu tradition. Often it is decorated with bright metal foils and other symbols of auspiciousness. It is offered during worship to a Hindu god or goddess. Irrespective of their religious affiliations, fishermen of India often offer it to the rivers and seas in the hopes of having bountiful catches. Hindus often initiate the beginning of any new activity by breaking a coconut to ensure the blessings of the gods and successful completion of the activity. The Hindu goddess of well-being and wealth, Lakshmi, is often shown holding a coconut. In the foothills of the temple town of Palani, before going to worship Murugan for the Ganesha, coconuts are broken at a place marked for the purpose. Every day, thousands of coconuts are broken, and some devotees break as many as 108 coconuts at a time as per the prayer. In tantric practices, coconuts are sometimes used as substitutes for human skulls .
In Hindu wedding ceremonies, a coconut is placed over the opening of a pot, representing a womb. Coconut flowers are auspicious symbols and are fixtures at Hindu and Buddhist weddings and other important occasions. In Kerala, coconut flowers must be present during a marriage ceremony. The flowers are inserted into a barrel of unhusked rice (paddy) and placed within sight of the wedding ceremony. Similarly in Sri Lanka, coconut flowers, standing in brass urns, are placed in prominent positions.
The Zulu Social Aid and Pleasure Club of New Orleans traditionally throws hand-decorated coconuts, the most valuable of Mardi Gras souvenirs, to parade revelers. The "Tramps" began the tradition circa 1901. In 1987, a "coconut law" was signed by Gov. Edwards exempting from insurance liability any decorated coconut "handed" from a Zulu float.
The coconut is also used as a target and prize in the traditional British fairground game "coconut shy". The player buys some small balls which he throws as hard as he can at coconuts balanced on sticks. The aim is to knock a coconut off the stand and win it.
Myths and legends
Some South Asian, Southeast Asian and Pacific Ocean cultures have origin myths in which the coconut plays the main role. In the Hainuwele myth from Maluku, a girl emerges from the blossom of a coconut tree. In Maldivian folklore one of the main myths of origin reflects the dependence of the Maldivians on the coconut tree.
According to an urban legend, there are more deaths caused by falling coconuts than by sharks annually.
Coconuts may help benign prostatic hyperplasia. In rats, virgin coconut oil reduced total cholesterol, triglycerides, phospholipids, LDL, and VLDL cholesterol levels and increased HDL cholesterol in serum and tissues. The hexane fraction of coconut peel may contain novel anticancer compounds. Young coconut juice has estrogen-like characteristics. Inside a coconut is a cavity filled with coconut water, which is sterile until opened. It mixes easily with blood, and was used during World War II in emergency transfusions. It can also serve as an emergency short-term intravenous hydration fluid. This is possible because the coconut water has a high level of sugar and other salts that makes it possible to be used in the bloodstream, much like the modern lactated Ringer solution or a dextrose/water solution as an intravenous solution (IV). Coconut is also commonly used as a traditional remedy in Pakistan to treat bites from rats. In Brazil, coconut is known as coco-da-bahia, coco-da-baía or coqueiro-da-índia. The tea from the husk fiber is widely used to treat several inflammatory disorders.
The leftover fiber from coconut oil and coconut milk production, coconut meal, is used as livestock feed. The dried calyx is used as fuel in wood-fired stoves. Coconut water is traditionally used as a growth supplement in plant tissue culture/micropropagation. The smell of coconuts comes from the 6-pentyloxan-2-one molecule, known as delta-decalactone in the food and fragrance industries.
Tool and shelter for animals
Researchers from the Melbourne Museum in Australia observed the octopus species Amphioctopus marginatus use of tools, specifically coconut shells, for defense and shelter. The discovery of this behavior was observed in Bali and North Sulawesi in Indonesia between 1998 and 2008. Amphioctopus marginatus is the first invertebrate known to be able to use tools.
A coconut can be hollowed out and used as a home for a rodent or small birds. Halved, drained coconuts can also be hung up as bird feeders, and after the flesh has gone, can be filled with fat in winter to attract tits.
Coconut can be a food allergen although its prevalence varies from country to country. While coconut is one of the top-five food allergies in India where it is a common food source, such allergies to coconut are considered rare in Australia, the UK, and the United States. As a result, commercial extracts of coconut are not currently available for skin prick testing in Australia or New Zealand.
Despite a low prevalence of allergies to coconut in the United States, the U.S. Food and Drug Administration (FDA) began identifying coconuts in October 2006. Based on FDA guidance and federal U.S. law, coconut must be disclosed as an ingredient.
Coconut-derived products can cause contact dermatitis. They can be present in cosmetics, including some shampoos, moisturizers, soaps, cleansers and hand washing liquids. Those known to cause contact dermatitis include: coconut diethanolamide, cocamide sulphate, cocamide DEA, CDEA, sodium laureth sulfate, sodium lauroyl sulfate, ammonium laureth sulfate, ammonium lauryl sulfate, sodium lauroyl sarcosinate, sodium cocoyl sarcosinate, potassium coco hydrolysed collagen, triethanolamine laureth sulfate, caprylic/capric triglycerides, triethanolamine lauryl or cocoyl sarcosime, disodium oleamide sulfocuccinate, laureth sulfasuccinate, and disodium dioctyl sulfosuccinate.

Maypan coconut palm
Maypan is an F1 hybrid coconut [palm] that was developed by the Research Department of the Coconut Industry Board of Jamaica to be resistant to Lethal Yellowing disease. It was created experimentally in 1962 by cross pollinating two varieties of Cocos nucifera and, after extensive disease exposure and yield performance trials, was named and released in 1974 when a suitable method of mass controlled pollination had been devised. A DwarfxTall hybrid, the Malayan Dwarf seed parents, grown in an isolated seed garden and kept constantly emasculated, are regularly pollinated by blowing a mixture of talc and pollen collected from selected palms of a variety known locally as Panama Tall. This combination gives the Maypan an LY disease resistance approaching that of the Malayan Dwarf and much of the windstorm tolerance of the Panama Tall. It grows to approximately 18 meters in height. The LY resistance of the Maypan, of both of its parents, and of other coconut varieties generally, has been called into question since the 1990s but Maypan, and F1 hybrids using the same types of parents, are still the planting material of choice in the Caribbean and Latin American countries where LY occurs.
