The peach (Prunus persica) is a deciduous tree native to the region of Northwest China between the Tarim Basin and the north slopes of the Kunlun Mountains, where it was first domesticated and cultivated.[3] It bears edible juicy fruits with various characteristics, most called peaches and others (the glossy-skinned varieties), nectarines.

The specific name persica refers to its widespread cultivation in Persia (modern-day Iran), from where it was transplanted to Europe. It belongs to the genus Prunus, which includes the cherry, apricot, almond, and plum, in the rose family. The peach is classified with the almond in the subgenus Amygdalus, distinguished from the other subgenera by the corrugated seed shell. Due to their close relatedness, the kernel of a peach stone tastes remarkably similar to almond, and peach stones are often used to make a cheap version of marzipan, known as persipan.[4]

Peaches and nectarines are the same species, though they are regarded commercially as different fruits. The skin of nectarines lacks the fuzz (fruit-skin trichomes) that peach skin has; a mutation in a single gene (MYB25) is thought to be responsible for the difference between the two.[5][6]

In 2018, China produced 62% of the world total of peaches and nectarines.[7]


Peach flowers

Prunus persica grows up to 7 m (23 ft) tall and wide, but when pruned properly, trees are usually 3–4 m (10–13 ft) tall and wide.[8] The leaves are lanceolate, 7–16 cm (3–6 12 in) long, 2–3 cm (341 14 in) broad, and pinnately veined. The flowers are produced in early spring before the leaves; they are solitary or paired, 2.5–3 cm diameter, pink, with five petals. The fruit has yellow or whitish flesh, a delicate aroma, and a skin that is either velvety (peaches) or smooth (nectarines) in different cultivars. The flesh is very delicate and easily bruised in some cultivars, but is fairly firm in some commercial varieties, especially when green. The single, large seed is red-brown, oval shaped, around 1.3–2 cm long, and surrounded by a wood-like husk. Peaches, along with cherries, plums, and apricots, are stone fruits (drupes). The various heirloom varieties including the 'Indian Peach', or 'Indian Blood Peach', which ripens in the latter part of the summer, and can have color ranging from red and white, to purple.[9]

Cultivated peaches are divided into clingstones and freestones, depending on whether the flesh sticks to the stone or not; both can have either white or yellow flesh. Peaches with white flesh typically are very sweet with little acidity, while yellow-fleshed peaches typically have an acidic tang coupled with sweetness, though this also varies greatly. Both colors often have some red on their skins. Low-acid, white-fleshed peaches are the most popular kinds in China, Japan, and neighbouring Asian countries, while Europeans and North Americans have historically favoured the acidic, yellow-fleshed cultivars.


The scientific name persica, along with the word "peach" itself and its cognates in many European languages, derives from an early European belief that peaches were native to Persia (modern-day Iran). The Ancient Romans referred to the peach as malum persicum "Persian apple", later becoming French pêche, whence the English "peach".[10] The scientific name, Prunus persica, literally means "Persian plum", as it is closely related to the plum.

Fossil record

Fossil endocarps with characteristics indistinguishable from those of modern peaches have been recovered from late Pliocene deposits in Kunming, dating to 2.6 million years ago. In the absence of evidence that the plants were in other ways identical to the modern peach, the name Prunus kunmingensis has been assigned to these fossils.[11]

Although its botanical name Prunus persica refers to Persia, genetic studies suggest peaches originated in China,[12] where they have been cultivated since the neolithic period. Until recently, cultivation was believed to have started around 2000 BC.[13][14] More recent evidence indicates that domestication occurred as early as 6000 BC in Zhejiang Province of China. The oldest archaeological peach stones are from the Kuahuqiao site. Archaeologists point to the Yangtze River Valley as the place where the early selection for favorable peach varieties probably took place.[15] Peaches were mentioned in Chinese writings and literature beginning from the early first millennium BC.[16]

A domesticated peach appeared very early in Japan, in 4700–4400 BC, during the Jōmon period. It was already similar to modern cultivated forms, where the peach stones are significantly larger and more compressed than earlier stones. This domesticated type of peach was brought into Japan from China. Nevertheless, in China itself, this variety is currently attested only at a later date around 3300 to 2300 BC.[15]

In India, the peach first appeared by about 1700 BC, during the Harappan period.[17]

It is also found elsewhere in Western Asia in ancient times.[18] Peach cultivation reached Greece by 300 BC.[14] Alexander the Great often is claimed to have introduced the fruit into Europe after he conquered the Persians,[18] although no historical evidence for this belief has been found.[19] Peaches were, however, well known to the Romans in the first century AD;[14] the oldest known artistic representations of the fruit are in two fragments of wall paintings, dated to the first century AD, in Herculaneum, preserved due to the Vesuvius eruption of 79 AD, and now held in the National Archaeological Museum in Naples.[20] Archaeological finds show that peaches were cultivated widely in Roman northwestern Continental Europe, but production collapsed around the sixth century; some revival of production followed with the Carolingian Renaissance of the 9th century.[21]

The peach was brought to the Americas by Spanish explorers in the 16th century, and eventually made it to England and France in the 17th century, where it was a prized and expensive treat. Horticulturist George Minifie supposedly brought the first peaches from England to its North American colonies in the early 17th century, planting them at his estate of Buckland in Virginia.[22] Although Thomas Jefferson had peach trees at Monticello, American farmers did not begin commercial production until the 19th century in Maryland, Delaware, Georgia, South Carolina, and finally Virginia.

In April 2010, an international consortium, the International Peach Genome Initiative, which include researchers from the United States, Italy, Chile, Spain, and France, announced they had sequenced the peach tree genome (doubled haploid Lovell). Recently, it published the peach genome sequence and related analyses. The sequence is composed of 227 million nucleotides arranged in eight pseudomolecules representing the eight peach chromosomes (2n = 16). In addition, 27,852 protein-coding genes and 28,689 protein-coding transcripts were predicted.

Particular emphasis in this study is reserved for the analysis of the genetic diversity in peach germplasm and how it was shaped by human activities such as domestication and breeding. Major historical bottlenecks were found, one related to the putative original domestication that is supposed to have taken place in China about 4,000–5,000 years ago, the second is related to the western germplasm and is due to the early dissemination of the peach in Europe from China and the more recent breeding activities in the United States and Europe. These bottlenecks highlighted the substantial reduction of genetic diversity associated with domestication and breeding activities.[23]

Peaches grow in a fairly limited range in dry, continental or temperate climates, since the trees have a chilling requirement that tropical or subtropical areas generally do not satisfy except at high altitudes (for example in certain areas of Ecuador, Colombia, Ethiopia, India, and Nepal). Most cultivars require 500 hours of chilling around 0 to 10 °C (32 to 50 °F). During the chilling period, key chemical reactions occur, but the plant appears dormant. Once the chilling period is fulfilled, the plant enters a second type of dormancy, the quiescence period. During quiescence, buds break and grow when sufficient warm weather favorable to growth is accumulated.[24]

The trees themselves can usually tolerate temperatures to around −26 to −30 °C (−15 to −22 °F), although the following season's flower buds are usually killed at these temperatures, preventing a crop that summer. Flower bud death begins to occur between −15 and −25 °C (5 and −13 °F), depending on the cultivar and on the timing of the cold, with the buds becoming less cold tolerant in late winter.[25]

Another climate constraint is spring frost. The trees flower fairly early (in March in Western Europe), and the blossom is damaged or killed if temperatures drop below about −4 °C (25 °F). If the flowers are not fully open, though, they can tolerate a few degrees colder.

Climates with significant winter rainfall at temperatures below 16 °C (61 °F) are also unsuitable for peach cultivation, as the rain promotes peach leaf curl, which is the most serious fungal disease for peaches. In practice, fungicides are extensively used for peach cultivation in such climates, with more than 1% of European peaches exceeding legal pesticide limits in 2013.[26]

Finally, summer heat is required to mature the crop, with mean temperatures of the hottest month between 20 and 30 °C (68 and 86 °F).

Typical peach cultivars begin bearing fruit in their third year. Their lifespan in the U.S. varies by region; the University of California at Davis gives a lifespan of about 15 years[27] while the University of Maine gives a lifespan of 7 years there.[28]


White peach of the clingstone variety
White peach of the clingstone variety

Hundreds of peach and nectarine cultivars are known. These are classified into two categories—freestones and clingstones. Freestones are those whose flesh separates readily from the pit. Clingstones are those whose flesh clings tightly to the pit. Some cultivars are partially freestone and clingstone, so are called semifree. Freestone types are preferred for eating fresh, while clingstone types are for canning. The fruit flesh may be creamy white to deep yellow, to dark red; the hue and shade of the color depend on the cultivar.[29]

Peach breeding has favored cultivars with more firmness, more red color, and shorter fuzz on the fruit surface. These characteristics ease shipping and supermarket sales by improving eye appeal. This selection process has not necessarily led to increased flavor, though. Peaches have a short shelf life, so commercial growers typically plant a mix of different cultivars to have fruit to ship all season long.[30]

Different countries have different cultivars. In the United Kingdom, for example, these cultivars have gained the Royal Horticultural Society's Award of Garden Merit:

  • 'Duke of York'[31]
  • 'Peregrine'[32]
  • 'Rochester'[33]
  • 'Lord Napier' (nectarine)[34]

The variety P. persica var. nucipersica (or var. nectarina), commonly called nectarine, has a smooth skin. It is on occasion referred to as a "shaved peach" or "fuzzless peach", due to its lack of fuzz or short hairs.


Peacherines are claimed to be a cross between a peach and a nectarine, but as they are the same species, cannot be a true cross (hybrid); they are marketed in Australia and New Zealand. The fruit is intermediate in appearance, though, between a peach and a nectarine, large and brightly colored like a red peach. The flesh of the fruit is usually yellow, but white varieties also exist. The Koanga Institute lists varieties that ripen in the Southern Hemisphere in February and March.[35][36]

Flat peaches

Flat peaches, or pan-tao, have a flattened shape, in contrast to ordinary near-spherical peaches.[37]

Most peach trees sold by nurseries are cultivars budded or grafted onto a suitable rootstock. Common rootstocks are 'Lovell Peach', 'Nemaguard Peach', Prunus besseyi, and 'Citation'.[38] The rootstock provides hardiness and budding is done to improve predictability of the fruit quality.

Peach trees need full sun, and a layout that allows good natural air flow to assist the thermal environment for the tree. Peaches are planted in early winter. During the growth season, they need a regular and reliable supply of water, with higher amounts just before harvest.[39]

Peaches need nitrogen-rich fertilizers more than other fruit trees. Without regular fertilizer supply, peach tree leaves start turning yellow or exhibit stunted growth. Blood meal, bone meal, and calcium ammonium nitrate are suitable fertilizers.

The flowers on a peach tree are typically thinned out because if the full number of peaches mature on a branch, they are undersized and lack flavor. Fruits are thinned midway in the season by commercial growers. Fresh peaches are easily bruised, so do not store well. They are most flavorful when they ripen on the tree and are eaten the day of harvest.[39]

The peach tree can be grown in an espalier shape. The Baldassari palmette is a design created around 1950 used primarily for training peaches. In walled gardens constructed from stone or brick, which absorb and retain solar heat and then slowly release it, raising the temperature against the wall, peaches can be grown as espaliers against south-facing walls as far north as southeast Great Britain and southern Ireland.


The first pest to attack the tree early in the year when other food is scarce is the earwig (Forficula auricularia) which feeds on blossoms and young leaves at night, preventing fruiting and weakening newly planted trees. The pattern of damage is distinct from that of caterpillars later in the year, as earwigs characteristically remove semicircles of petal and leaf tissue from the tips, rather than internally. Greasebands applied just before blossom are effective.[40][failed verification]

The larvae of such moth species as the peachtree borer (Synanthedon exitiosa), the yellow peach moth (Conogethes punctiferalis), the well-marked cutworm (Abagrotis orbis), Lyonetia prunifoliella, Phyllonorycter hostis, the fruit tree borer (Maroga melanostigma), Parornix anguliferella, Parornix finitimella, Caloptilia zachrysa, Phyllonorycter crataegella, Trifurcula sinica, Suzuki's promolactis moth (Promalactis suzukiella), the white-spotted tussock moth (Orgyia thyellina), the apple leafroller (Archips termias), the catapult moth (Serrodes partita), the wood groundling (Parachronistis albiceps) or the omnivorous leafroller (Platynota stultana) are reported to feed on P. persica. The flatid planthopper (Metcalfa pruinosa) causes damage to fruit trees.

The tree is also a host plant for such species as the Japanese beetle (Popillia japonica), the unmonsuzume (Callambulyx tatarinovii), the promethea silkmoth (Callosamia promethea), the orange oakleaf (Kallima inachus), Langia zenzeroides, the speckled emperor (Gynanisa maja) or the brown playboy (Deudorix antalus). The European red mite (Panonychus ulmi) or the yellow mite (Lorryia formosa) are also found on the peach tree.

It is a good pollen source for honey bees and a honeydew source for aphids.


Peach trees are prone to a disease called leaf curl, which usually does not directly affect the fruit, but does reduce the crop yield by partially defoliating the tree. Several fungicides can be used to combat the disease, including Bordeaux mixture and other copper-based products (the University of California considers these organic treatments), ziram, chlorothalonil, and dodine.[41] The fruit is susceptible to brown rot or a dark reddish spot.


Peaches and nectarines are best stored at temperatures of 0°C (32°F) and in high humidity.[29] They are highly perishable, so are typically consumed or canned within two weeks of harvest.

Peaches are climacteric[42][43][44] fruits and continue to ripen after being picked from the tree.[45]

 United States
Source: United Nations, FAOSTAT[7]

In 2018, world production of peaches (combined with nectarines for reporting) was 24.5 million tonnes, led by China with 62% of the world total (table).

The U.S. state of Georgia is known as the "Peach State" due to its significant production of peaches as early as 1571,[46] with exports to other states occurring around 1858.[47] In 2014, Georgia was third in US peach production behind California and South Carolina.[46]

Cultural significance

Peaches are not only a popular fruit, but also are symbolic in many cultural traditions, such as in art, paintings, and folk tales such as Peaches of Immortality.


Peach blossoms are highly prized in Chinese culture. The ancient Chinese believed the peach to possess more vitality than any other tree because their blossoms appear before leaves sprout. When early rulers of China visited their territories, they were preceded by sorcerers armed with peach rods to protect them from spectral evils. On New Year's Eve, local magistrates would cut peach wood branches and place them over their doors to protect against evil influences.[48] Peach wood was also used for the earliest known door gods during the Han. Another author writes:

The Chinese also considered peach wood (t'ao-fu) protective against evil spirits, who held the peach in awe. In ancient China, peach-wood bows were used to shoot arrows in every direction in an effort to dispel evil. Peach-wood slips or carved pits served as amulets to protect a person's life, safety, and health.[49]

Peachwood seals or figurines guarded gates and doors, and, as one Han account recites, "the buildings in the capital are made tranquil and pure; everywhere a good state of affairs prevails".[49] Writes the author, further:

Another aid in fighting evil spirits were peach-wood wands. The Li-chi (Han period) reported that the emperor went to the funeral of a minister escorted by a sorcerer carrying a peachwood wand to keep bad influences away. Since that time, peachwood wands have remained an important means of exorcism in China.[49]

Peach kernels (桃仁 táo rén) are a common ingredient used in traditional Chinese medicine to dispel blood stasis, counter inflammation, and reduce allergies.[50]

In an orchard of flowering peach trees, Liu Bei, Guan Yu, and Zhang Fei took an oath of brotherhood in the opening chapter of the classic Chinese novel Romance of the Three Kingdoms. Another peach orchard, in "The Peach Blossom Spring" by poet Tao Yuanming, is the setting of the favourite Chinese fable and a metaphor for utopias. A peach tree growing on a precipice was where the Taoist master Zhang Daoling tested his disciples.[51]

The Old Man of the South Pole, one of the deities of the Chinese folk religion fulu shou, is sometimes seen holding a large peach, representing long life and health.

The term "bitten peach", first used by Legalist philosopher Han Fei in his work Han Feizi, became a byword for homosexuality. The book records the incident when courtier Mizi Xia bit into an especially delicious peach and gave the remainder to his lover, Duke Ling of Wei, as a gift so that he could taste it, as well.


In Korea, peaches have been cultivated from ancient times. According to Samguk Sagi, peach trees were planted during the Three Kingdoms of Korea period, and Sallim gyeongje also mentions cultivation skills of peach trees. The peach is seen as the fruit of happiness, riches, honours, and longevity. The rare peach with double seeds is seen as a favorable omen of a mild winter. It is one of the 10 immortal plants and animals, so peaches appear in many minhwa (folk paintings). Peaches and peach trees are believed to chase away spirits, so peaches are not placed on tables for jesa (ancestor veneration), unlike other fruits.[52][53]


The world’s sweetest peach happens to grow in Fukushima, Japan. The Guinness world record for the sweetest peach is currently held by a peach grown in Kanechika, Japan, with a sugar content of 22.2%. However, a fruit farm in rural Fukushima, Koji grew a much sweeter peach, with a Brix score of 32°. Degrees Brix measures the sugar content of the fruit, and is usually between 11 and 15 for a typical peach from a supermarket.[54]


A Vietnamese mythic history states that in the spring of 1789, after marching to Ngọc Hồi and then winning a great victory against invaders from the Qing dynasty of China, Emperor Quang Trung ordered a messenger to gallop to Phú Xuân citadel (now Huế) and deliver a flowering peach branch to the Princess Ngọc Hân. This took place on the fifth day of the first lunar month, two days before the predicted end of the battle. The branch of peach flowers that was sent from the north to the centre of Vietnam was not only a message of victory from the King to his wife, but also the start of a new spring of peace and happiness for all the Vietnamese people. In addition, since the land of Nhật Tân had freely given that very branch of peach flowers to the King, it became the loyal garden of his dynasty.

The protagonists of The Tale of Kieu fell in love by a peach tree, and in Vietnam, the blossoming peach flower is the signal of spring. Finally, peach bonsai trees are used as decoration during Vietnamese New Year (Tết) in northern Vietnam.


Pierre-Auguste Renoir, A Still Life Painting of Peaches, 1881-82
Pierre-Auguste Renoir, A Still Life Painting of Peaches, 1881-82

Many famous artists have painted with peach fruits placed in prominence. Caravaggio, Vicenzo Campi, Pierre-Auguste Renoir, Claude Monet, Édouard Manet, Henri Fantin-Latour, Severin Roesen, Peter Paul Rubens, and Van Gogh are among the many influential artists who painted peaches and peach trees in various settings.[55][56] Scholars suggest that many compositions are symbolic, some an effort to introduce realism.[57] For example, Tresidder claims[58] the artists of Renaissance symbolically used peach to represent heart, and a leaf attached to the fruit as the symbol for tongue, thereby implying speaking truth from one's heart; a ripe peach was also a symbol to imply a ripe state of good health. Caravaggio paintings introduce realism by painting peach leaves that are molted, discolored, or in some cases have wormholes – conditions common in modern peach cultivation.[56]

United States

South Carolina named the peach its official fruit in 1984.[59] The peach became the state fruit of Georgia, nicknamed the "Peach State", in 1995.[60] The peach went from feral trees utilized opportunistically to a tended commercial crop in the Southern United States in the 1850s, as the boll weevil attacked regional cotton crops. When Georgia reached peak production in the 1920s, elaborate festivals celebrated the fruit. By 2017, Georgia's production represented 3–5% of the U.S. total.[61][62] Alabama named it the "state tree fruit" in 2006.[63] Delaware's state flower has been the peach blossom since 1995,[64] and peach pie became its official dessert in 2009.[65]

Nutrition and research


The phytochemical amygdalin – a cyanogenic glycoside present in peach seeds, skin, and pulp[66] – is toxic if consumed in large doses.[67]
