The pomegranate ( Punica granatum) is a fruit-bearing, deciduous shrub in the family Lythraceae, subfamily Punica, that grows to between tall. Rich in symbolic and mythological associations in many cultures, it originated from the Iranian plateau including Iran, the Caucasus, Turkmenistan, Afghanistan and Pakistan. Pomegranate was first domesticated by ancient Iranians in the Iranian plateau and nearby regions about 5,000 years ago. It is extensively cultivated for its fruit.
Pomegranate was exported from the Iranian plateau to other parts of Asia including Iraq, Turkey, India, Africa, and Europe. It was also introduced into Spanish America in the late 16th century and into California by New Spain in 1769.
Although the pomegranate is indigenous to Iran and its nearby regions, it is also nowadays cultivated across the West Asia, South Asia, Central Asia, North Africa and tropical Africa, the drier parts of Southeast Asia, the Mediterranean Basin, United States and Chile. The fruit is typically in season in the Northern Hemisphere from September to February, and in the Southern Hemisphere from March to May.
Pomegranate molasses is a key ingredient in traditional Iranian cuisine, where it is used to add a rich sweet-sour flavour to dishes such as stews, sauces, and marinades, most notably in classic recipes like fesenjān, kabab torsh and zeytoon parvardeh. The pomegranate and its juice are variously used in baking, cooking, juice blends, garnishes, nonalcoholic drinks, and .
Etymology
The name
pomegranate derives from
medieval Latin pōmum, apple and grānātum, seeded.
Possibly stemming from the old French word for the fruit, pomme-grenade, the pomegranate was known in early English as "apple of
Granada", a term that today survives only in heraldic
.
Garnet derives from Old French grenat by metathesis, from Medieval Latin granatum as used in a different meaning "of a dark red colour". This derivation may have originated from pomum granatum, describing the colour of pomegranate pulp, or from granum, referring to red dye, cochineal.
The modern French term for pomegranate, grenade, has given its name to the military grenade.
Pomegranates were colloquially called wineapples or wine-apples in Ireland, although this term has fallen out of use. It still persists at the Moore Street open-air market in central Dublin.
Description
The pomegranate is a
shrub or small tree growing high, with multiple spiny branches.
It is long-lived, with some specimens in France surviving for 200 years.
The
leaf are opposite or subopposite, glossy, narrow oblong, entire, long, and broad.
The are bright red or white, and or more in diameter, with three to seven petals. Some fruitless are grown for the flowers alone.
The flower's anthers close around the stigma until maturity, the ovaries are divided internally into compartments or locules of many suspended covered in septum.
The pomegranate fruit husk is red-purple with an outer, hard pericarp, and an inner, spongy mesocarp (white "albedo"), which comprises the fruit's inner wall where seeds attach. Membranes of the mesocarp are organised as nonsymmetric chambers that contain seeds which are embedded without attachment to the mesocarp, also a result of fertilisation to the divided ovary. Pomegranate seeds are characterised by having sarcotesta, thick fleshy seed coats derived from the integuments or outer layers of the ovule's . The number of seeds in a pomegranate can vary from 200 to about 1,400. Botanically, the fruit is a berry with edible seeds and pulp produced from the ovary of a single flower. The fruit is variable in size, from diameter in wild plants (to in some cultivars) with a rounded shape and thick, reddish husk. In mature fruit, the juice obtained by compressing the seeds yields a tart flavour due to low pH (4.4) and high contents of , which may cause a red indelible stain on fabrics. The of pomegranate juice primarily results from the presence of and ellagitannins.

Cultivation
P. granatum is grown for its fruit crop, and as
and shrubs in parks and gardens. Mature specimens can develop sculptural twisted bark, multiple trunks, and a distinctive overall form. Pomegranates are
drought-tolerant, and can be grown in dry areas with either a Mediterranean winter rainfall climate or in summer rainfall climates. In wetter areas, they can be prone to root decay from
fungus diseases. They can tolerate moderate
frost, down to about .
Insect pests of the pomegranate can include the butterflies Virachola isocrates, Iraota timoleon, and Deudorix epijarbas, and the leaf-footed bug Leptoglossus zonatus. Fruit flies and ants are attracted to unharvested ripe fruit.
Propagation
P. granatum reproduces sexually in nature, but can be propagated asexually. Propagation methods include layering, hardwood cuttings, softwood cuttings, and tissue culture. Required conditions for rooting cuttings include warm temperatures within the 18–29 °C (65–85 °F) range and a semihumid environment.
Auxin increases rooting success rate, but is not required.
Varieties
P. granatum var.
nana is a dwarf variety of
P. granatum popularly planted as an
ornamental plant in gardens and larger containers, and used as a
bonsai specimen tree. It could well be a wild form with a distinct origin. It has gained the Royal Horticultural Society's Award of Garden Merit.
The only other species in the genus Punica is the Socotran pomegranate ( P. protopunica), which is endemic to the archipelago of four islands in the Arabian Sea. The territory is part of Yemen. It differs in having pink (not red) flowers and smaller, less sweet fruit.
Cultivars
P. granatum has more than 500 named
, but has considerable synonymy in which the same
genotype is named differently across regions of the world.
Several characteristics between pomegranate genotypes vary for identification, consumer preference, preferred use, and
marketing, the most important of which are fruit size,
exocarp colour (ranging from yellow to purple, with pink and red most common), seed coat colour (ranging from white to red), the hardness of seed, maturity, juice content and its acidity, sweetness, and
astringency.
Production and export
The leading producers globally are India and China, followed by Iran, Turkey, Afghanistan, the US, Iraq, Pakistan, Syria, and Spain.
During 2019, Chile, Peru, Egypt, Israel, India, and Turkey supplied pomegranates to the
European Union market.
Chile was the main supplier to the United States market, which has a limited supply from Southern California.
China was self-sufficient for its pomegranate supply in 2019, while other
South Asia markets were supplied mainly by India.
Pomegranate production and exports in
South Africa competed with South American shipments in 2012–2018, with export destinations including Europe, the
Middle East, the
United Kingdom, and Russia.
South Africa imports pomegranates mainly from Israel.
History
The pomegranate is native to
Iran and it was first domesticated by ancient Iranians in the
Iranian plateau and nearby regions about 5,000 years ago.
Archaeological and historical evidence shows that the pomegranate, especially its blossom (
golnār), was a sacred and symbolic element in ancient Persian culture from prehistoric times through the Achaemenid period in about 500 BC, associated with fertility, abundance, royal authority, and the deities
Mithra and
Anahita.
There is a petroglyph at
Persepolis showing that a pomegranate flower in the hand of an Achaemenian king, highlighting its ritual and symbolic significance in imperial iconography.
In Pakistan, it grows wild between 1,000–2,000 metres altitude, mainly in the western part of the country. Pomegranates have been cultivated throughout the Middle East, India, and the Mediterranean region for several millennia, and it is also cultivated in the Central Valley of California and in Arizona. Pomegranates may have been domesticated as early as the fifth millennium BC, as they were one of the first fruit trees to be domesticated in the eastern Mediterranean region.
Remains of the fruit dating to the Neolithic period have been found at Gezer in Israel, and carbonised pomegranate exocarp has been recovered from early Bronze Age levels at Tell es-Sultan in the West Bank. Additional remains from this period have been found at Tel Arad and Gezer in Israel. Evidence from the Late Bronze Age includes pomegranate remains at Hala Sultan Tekke in Cyprus and the site of Tiryns in Greece. A large, dry pomegranate was found in the tomb of Djehuty, the butler of Queen Hatshepsut in Egypt; Mesopotamian records written in cuneiform mention pomegranates from the mid-third millennium BC onwards.
Waterlogged pomegranate remains have been identified at the circa 14th century BC Uluburun shipwreck off the coast of Turkey. Other goods on the ship include perfume, ivory and gold jewelry, suggesting that pomegranates at this time may have been considered a luxury good. Other archaeological finds of pomegranate remains from the Late Bronze Age have been found primarily in elite residences, supporting this inference. During the Iron Age, the fruit was a frequent decorative motif in Israelites material culture, appearing on ancient artifacts.
It is extensively grown in southern China and Southeast Asia, whether originally spread along the Silk Road route or brought by sea traders. Kandahar is famous in Afghanistan for its high-quality pomegranates.
The pomegranate was introduced as an exotic to England in the 17th century by John Tradescant the Elder, but the disappointment that it did not set fruit there led to its repeated introduction to the American colonies, even New England. It succeeded in the South: Bartram received a barrel of pomegranates and oranges from a correspondent in Charleston, South Carolina, 1764. John Bartram partook of "delitious" pomegranates with Noble Jones at Wormsloe Plantation, near Savannah, Georgia, in September 1765. Thomas Jefferson planted pomegranates at Monticello in 1771; he had them from George Wythe of Williamsburg.

Use
Culinary
Pomegranate juice can be sweet or
Sourness, but most fruit are moderate in taste, with sour notes from the acidic
contained in the juice.
Pomegranate juice has long been a common drink in Europe and the Middle East, and is distributed worldwide.
Grenadine syrup, commonly used in
, originally consisted of thickened and sweetened pomegranate juice,
Before tomatoes (a New World fruit) arrived in the Middle East, pomegranate juice, pomegranate molasses, and vinegar were widely used in Iranian foods; this mixture is found in traditional recipes such as fesenjān, a thick sauce made from pomegranate juice and ground , usually spooned over duck or other poultry and rice, and in ash-e anar (pomegranate soup).
In Turkey, pomegranate sauce () is used as a salad dressing, to marinate meat, or simply to drink. Pomegranate seeds are used in salads and sometimes as garnish for desserts such as güllaç. Pomegranate syrup, also called pomegranate molasses, is used in muhammara, a roasted Capsicum, walnut, and garlic spread popular in Syria and Turkey.
In Mexico, pomegranate seeds are used to adorn the traditional dish chiles en nogada, representing the red of the Mexican flag in the dish which evokes the green (poblano pepper), white ( nogada sauce) and red (pomegranate seeds).

Phytochemicals
The most abundant
phytochemicals in pomegranate juice are
, including the hydrolyzable tannins called
ellagitannins formed when
ellagic acid and
gallic acid bind with a
carbohydrate to form pomegranate ellagitannins, also known as
punicalagins.
The red colour of the juice is attributed to

such as
delphinidin,
cyanidin, and
of
pelargonidin.
Generally, an increase in juice
pigmentation occurs during fruit ripening.
The
phenols content of pomegranate juice is degraded by processing and
pasteurisation techniques.
Pomegranate peel contains high amount of polyphenols, condensed tannins,
catechins, and
prodelphinidins.
The higher phenolic content of the peel yields

Health claims
Despite limited research data, manufacturers and marketers of pomegranate juice have liberally used results from preliminary research to promote products.
In February 2010, the FDA issued a warning letter to one such manufacturer,
POM Wonderful, for using published literature to make illegal claims of unproven antidisease effects.
In May 2016, the US Federal Trade Commission declared that POM Wonderful could not make health claims in its advertising; the US Supreme Court upheld the FTC decision.
Symbolism
In ancient
Assyria, pomegranates were commonly depicted,
indicating abundance and fruitfulness with the agricultural cycle.
In ancient Iran, the pomegranate tree was believed to be grown from places where the blood of the hero Siyâvash was spilled. The Zoroastrians of Iran serve it in their festivals of
Mehregan and
Nowruz, and in wedding ceremonies. They used to plant a pomegranate tree in their fire temples to use its leaves in their ceremonies.
Ancient Egyptians regarded the pomegranate as a symbol of prosperity and ambition.
According to the
Ebers Papyrus, Egyptians used the pomegranate to treat tapeworm infections.
In ancient Greece, a pomegranate is displayed on coins from Side, a city named for the fruit.
[Turkish Odyssey Perge-Aspendus-Side-Alanya ] In Ancient Greek mythology, the pomegranate was known as the "fruit of the dead", and believed to have sprung from the blood of
Adonis.
The myth of
Persephone, the goddess of the
Greek underworld, features her consumption of pomegranate seeds, requiring her to spend a certain number of months in the underworld every year. During the months that she sits on the throne of the underworld beside her husband
Hades, her mother
Demeter mourns and no longer gives fertility to the earth.
The pomegranate is one of the Seven Species of fruit and grains listed in the Hebrew Bible as special products of the Land of Israel. A fourth-century floor mosaic from Hinton St Mary, Dorset depicts the bust of Christ and the chi rho flanked by pomegranates. In Islam, Ar-Rahman of the Quran mentions the pomegranate as a "favour" among many to be offered to those fearful to the "Allah" in "two Jannah".
The pomegranate is a symbol in Armenia, representing fertility, abundance, and marriage. Every autumn, the Goychay Pomegranate Festival is held in the city of Goychay in Azerbaijan.[ iguide.travel Goychay Activities: Pomegranate Festival] In Palestinian culture, the pomegranate symbolises fertility and is deeply embedded in folklore and traditions. Introduced to China during the Han dynasty (206 BC – 220 AD), the pomegranate was an emblem of fertility, and pictures of the ripe fruit with the seeds bursting forth were hung in homes. In some Hindu traditions, the pomegranate) symbolises prosperity and fertility, and is associated with both Bhumidevi (the earth goddess) and Ganesha (fond of the many-seeded fruit).
