Opuntia, commonly called the prickly pear cactus, is a genus of in the cactus family Cactaceae, many known for their flavorful fruit and showy flowers. Cacti are native to the Americas, and are well adapted to aridity; however, they are still vulnerable to alterations in precipitation and temperature driven by climate change. The plant has been introduced to parts of Australia, southern Europe, the Middle East, and northern Africa.
Prickly pear alone is more commonly used to refer exclusively to the fruit, but may also be used for the plant itself; in addition, other names given to the plant and its specific parts include tuna (fruit), sabra, sabbar, nopal (pads, plural nopales) from the Nahuatl word nōpalli, nostle (fruit) from the Nahuatl word nōchtli, and paddle cactus. The genus is named for the Ancient Greece city of Opus. The fruit and leaves are edible. The most common culinary art is the "Barbary fig" ( Opuntia ficus-indica).
Opuntia is regarded as an aggressive invasive species.
Considerable variation of taxonomy occurs within Opuntia species, resulting in names being created for variants or subtypes within a species, and use of DNA sequencing to define and isolate various species.
Opuntia species are the most cold-tolerant of the lowland cacti, extending into western and southern Canada. One subspecies, Opuntia fragilis, has been found growing along the Beatton River in north-eastern British Columbia, southwest of Cecil Lake at 56° 17' N latitude and 120° 39' W longitude. Others are seen in the Kleskun Hills Natural Area of north-west Alberta at 55° 15' 30' N latitude and 118° 30' 36' W longitude.
Prickly pears produce a fruit known as tuna, commonly eaten in Mexico and in the Mediterranean region, which is also used to make aguas frescas. The fruit can be red, wine-red, green, or yellow-orange. In the Galápagos Islands, the Galápagos prickly pear, O. galapageia, has previously been treated as a number of different species, but is now only divided into varieties and subvarieties. Most of these are confined to one or a few islands, so they have been described as "an excellent example of adaptive radiation".Fitter, Fitter, and Hosking, Wildlife of the Galapagos (2000) On the whole, islands with tall, trunked varieties are also the home of giant tortoises, whereas islands lacking tortoises have low or prostrate forms of Opuntia. Prickly pears are a prime source of food for the common giant tortoises in the Galápagos Islands, so they are important in the food web.
Charles Darwin was the first to note that the cacti have thigmotaxis . When the anthers are touched, they curl over, depositing their pollen on the pollinator. That movement can be seen by gently poking the anthers of an open Opuntia flower. The same trait has evolved convergently in other genera (e.g. Lophophora).
Prickly pears (mostly O. stricta) were originally imported into Europe during the 16th century. They are now found in the Mediterranean region of Northern Africa, especially in Algeria, Morocco and Tunisia, where they grow all over the countryside, and in parts of Southern Europe, especially Spain, where they can be found in the east, south-east, and south of the country, and also in Malta, where they grow all over the islands, and in southern Italy, especially in Sicily and Sardinia. They can be found in enormous numbers in parts of South Africa, where they were introduced from South America. The prickly pear is considered an invasive species in Australia, Ethiopia, South Africa, and Hawaii, among other locations.
The first introduction of prickly pears into Australia is ascribed to the founding governor of the New South Wales colony, Arthur Phillip, and the earliest European colonists, in 1788. Brought from Brazil to Sydney, they were most likely O. monacantha. That variety did not spread beyond the east coast. However, a number of other types of prickly pear were introduced to Australian gardens in the mid-19th century. The cactus was also used as agricultural fencing and a feedstock for animals in times of drought,Patterson, Ewen K. 1936. The World's First Insect Memorial. "The Review of the River Plate", December pp. 16–17 as well as in an attempt to establish a cochineal dye industry.
The cactus became a widespread invasive weed in the dry interior climate west of the Great Dividing Range, in New South Wales and Queensland, eventually converting of farming land into an impenetrable green jungle of prickly pears in places high. Scores of farmers were driven off their land by what they called the "green hell", and their abandoned homes were crushed under the cactus growth, which advanced at a rate of per year.
In 1919, the Australian federal government established the Commonwealth Prickly Pear Board to coordinate efforts with state governments to eradicate the weed. Early attempts, comprising mechanical removal and poisonous chemicals failed. As a last resort, biological control was attempted. In 1925, the Cactoblastis cactorum moth was introduced from South America, and its larvae rapidly began to control the infestation. Alan Dodd, the son of the noted entomologist Frederick Parkhurst Dodd, was a leading official in combating the prickly pear menace. A memorial hall in Boonarga, Queensland, commemorates the efforts of the moth. The release of cochineal insects, which eat the cactus and simultaneously kill the plant, has also proven an effective measure for combating its spread.
Natural distribution of the plant occurs via consumption and associated seed dispersal by many animals, including , nonhuman , , birds, and humans. When ingested by elephants, the sharp components of the plant cause harm to the mouth, stomach, and intestines.
Opuntia species are primarily pollinated by , including some bee genera ( Diadasia and Lithurgus) that contain specialist pollinators (Oligolecty) that exclusively visit Opuntia.J.A. Reyes-Agüero, J.R. Aguirre R., A. Valiente-Banuet (2006) Reproductive biology of Opuntia: A review. Journal of Arid Environments
Animals that eat Opuntia include the prickly pear island snail and Cyclura rock iguanas. The fruit are relished by many arid-land animals, chiefly birds, which thus help distribute the seeds. Opuntia include the sac fungus Colletotrichum coccodes and Sammons' Opuntia virus. The ant, Crematogaster opuntiae, and spider, Theridion opuntia, are named because of their association with the prickly pear cactus.
In Mexico, prickly pears are often used to make appetizers, soups, salads, entrees, vegetable dishes, breads, desserts, beverages, candy, fruit preserves, and drinks. The young Plant stem segments, usually called pads or nopales, are also edible in most species of Opuntia. They are commonly used in Mexican cuisine in dishes such as huevos con nopales (eggs with nopal), or de nopales. Nopales are also an important ingredient in New Mexican cuisine. In 2009 it was introduced as a cheaper alternative to corn for the production of tortillas and other corn products. They can also be pickled.
Opuntia ficus-indica has been introduced to Europe, and flourishes in areas with a suitable climate, such as the south of France and southern Italy: In Sicily, they are referred to as fichi d'India (Italian literal translation of Indian fig) or ficurinia (Sicilian language literal translation of Indian fig). In Sardinia, they are called figumorisca ("Moorish figs"), the same denomination they receive along the Catalan language-speaking regions of the Western Mediterranean, figa de moro. They can be found also in the Struma River in Bulgaria, in southern Portugal and Madeira (where they are called tabaibo, figo tuno, or "Indian figs"), in Andalusia, Spain (where they are known as higos chumbos).
In Greece, it grows in such places as the Peloponnese region, Ionian Islands, or Crete, and its figs are known as frangosyka (Frankish, i.e. Western European, figs) or pavlosyka ("Paul's figs"), depending on the region. In Albania, they are called fiq deti translated as "sea figs", and are present in the south-west shore. The figs are also grown in Cyprus, where they are known as papoutsósyka or babutsa ("shoe figs").
The prickly pear also grows widely on the islands of Malta, where it is enjoyed by the Maltese as a typical summer fruit (known as bajtar tax-xewk, literally "spiny figs"), as well as being used to make the popular liqueur known as bajtra. The prickly pear is so commonly found in the Maltese islands, it is often used as a dividing wall between many of Malta's characteristic terraced fields in place of the usual rubble walls.
The prickly pear was introduced to Eritrea during the period of Italian colonisation between 1890 and 1940. It is locally known there as beles and is abundant during the late summer and early autumn (late July through September). The beles from the holy monastery of Debre Bizen is said to be particularly sweet and juicy.
In Morocco, Tunisia, Libya, Saudi Arabia, Jordan, and other parts of North Africa and the Middle East, prickly pears of the yellow and orange varieties are grown by the side of farms, beside railway tracks and other otherwise noncultivable land. It is sold in summer by street vendors, and is considered a refreshing fruit for that season.
Tungi is the local Saint Helena name for cactus pears. The plants (Indian fig opuntia) were originally brought to the island by the colonial ivory traders from East Africa in the 1850s. Tungi cactus now grows wild in the dry coastal regions of the island. Three principal cultivars of tungi grow on the island: the "English" with yellow fruit; the "Madeira" with large red fruit; and the small, firm "spiny red". Tungi also gives its name to a local Spirit distilled at The St Helena distillery at Alarm Forest, the most remote distillery in the world, made entirely from the opuntia cactus.
Cactus pear is being promoted and researched by ICARDA for India, Jordan, and Pakistan especially. It is an underappreciated crop in these countries and has undergone recent expansion in cultivated area. In some particularly promising areas of India and Pakistan it has given a 30% increase in milk yield /hectare (/acre).
Prior to modern medicine, Native Americans and Mexicans primarily used Opuntia as a coagulant for open wounds, using the pulp of the stem either by splitting the stem or scraping out the pulp.
In one recent study, it was found that Opuntia aided in the prevention or slow down of diabetes, obesity, metabolic syndrome, cardiovascular disease, and some cancers. The results of the group that was taking Opuntia showed a reduction in BMI, body composition, and waist circumference when compared to the placebo group.Mayes, V., Lacy, B. B., Ahasteen, J., & Chee, J. (2012). Nanise’: A Navajo herbal: One Hundred Plants from the Navajo Reservation. Chandler, AZ: Five Star Publications, Inc.
Cochineal is used primarily as a red food colouring and for cosmetics. The cochineal dye was used by the Aztec and Maya peoples of Central and North America, and by the Inca in South America. Produced almost exclusively in Oaxaca, Mexico, by indigenous producers, cochineal became Mexico's second-most valued export after silver. The dyestuff was consumed throughout Europe, and was so highly valued, its price was regularly quoted on the London and Amsterdam Commodity Exchanges.
The biggest producers of cochineal are Peru, the Canary Islands, and Chile. Current health concerns over artificial food additives have renewed the popularity of cochineal dyes, and the increased demand is making cultivation for insect farming an attractive opportunity in other regions, such as in Mexico, where cochineal production had declined again owing to the numerous natural enemies of the scale insect.
Apart from cochineal, the red dye betanin can be extracted from some Opuntia plants themselves. The Navajo people have traditionally produced a reddish dye from the fruit of the prickly pear cactus, used in dyeing woolen yarns.
The 1975–1988 version of the emblem of Malta also featured a prickly pear, along with a traditional dgħajsa, a shovel and pitchfork, and the rising sun.
The prickly pear is the official plant of Texas by legislation from 1995.
The cactus lends its name to a song by British jazz/classical group Portico Quartet. The song "My Rival", on the album Gaucho by the American jazz-pop group Steely Dan begins with the words, "The wind was driving in my face/The smell of prickly pear."
In the fall of 1961, Cuba had its troops plant a barrier of Opuntia cactus along the northeastern section of the fence surrounding the Guantanamo Bay Naval Base to stop Cubans from escaping Cuba to take refuge in the United States. This was dubbed the "Cactus Curtain", an allusion to Europe's Iron Curtain and the Bamboo Curtain in East Asia.
Uruguayan-born footballer Bruno Fornaroli is nicknamed prickly pear due to his sometimes spiky hairstyles.

Ecology
O. ficus-indica thrives in regions with mild winters having a prolonged dry spell followed by hot summers with occasional rain and relatively low humidity. A mean annual rainfall of provides good growth rates. O. ficus-indica proliferates in various soils ranging from subacid to subalkaline, with clay content not exceeding 15–20% and the soil well drained. The shallow root system enables the plant to grow in shallow, loose soils, such as on mountain slopes. Opuntia spreads into large clonal colonies, which contribute to its being considered a noxious weed in some places.

Toxicity
Although the plants are edible, the pointed hairs should not be eaten, and similar species with milky sap are suspect. (2025). 9781602396920, Skyhorse Publishing; United States Department of the Army. . ISBN 9781602396920
Uses
Nutrition
Raw opuntia leaves are 88% water, 10% , and less than 1% both of protein and fat (table). In a reference amount of , raw leaves provide of food energy, 16% of the Daily Value (DV) for vitamin C, and 20% DV for magnesium, with no other in significant content (table).
Regional food uses
The fruit of prickly pears, commonly called cactus fruit, cactus fig, Indian fig (meaning "Native American", not "of India"), nopales or tuna in Spanish, is edible, although it must be peeled carefully to remove the small spines on the outer skin before consumption. If the outer layer is not properly removed, can be ingested, causing discomfort of the throat, lips, and tongue, as the small spines are easily lodged in the skin. Native Americans like the Tequesta would roll the fruit around in a suitable medium (e.g. ) to "sandpaper" off the glochids. Alternatively, rotating the fruit in the flame of a campfire or torch has been used to remove the glochids. Today, Parthenocarpy (seedless) are also available. The seeds can be used for flour.
Folk medicine
In Mexican folk medicine, its pulp and juice are considered treatments for wounds and inflammation of the digestive tract and , although there is no high-quality evidence for any clinical benefit of using opuntia for these purposes.
Other uses
Dye production
Dactylopius coccus is a scale insect from which cochineal dye is derived. D. coccus itself is native to tropical and subtropical South America and Mexico. This insect, a primarily sessile parasite, lives on cactus from the genus Opuntia, feeding on moisture and nutrients in the cactus sap. The insect produces carminic acid, which deters predation by other insects. The carminic acid can be extracted from the insect's body and eggs to make the red dye.
Animal fodder
Cactus is used as a fodder crop for animals in arid and dryland regions. Some farmers prepare it with a fermentation method to remove the spines and increase digestibility.
Vegan leather
The thick skin of nopal cactus can be harvested as an environmentally-friendly leather replacement.
Biofuel
Bioethanol can be produced from some Opuntia species.
Culture
The prickly pear cactus has been used for centuries both as a food source and a natural fence that keeps in livestock and marks the boundaries of family lands. They are resilient and often grow back following removal.
Mexico
The coat of arms of Mexico depicts a Mexican golden eagle, perched upon an Opuntia cactus, holding a rattlesnake. According to the official history of Mexico, the coat of arms is inspired by an Aztec legend regarding the founding of Tenochtitlan. The Aztecs, then a nomadic tribe, were wandering throughout Mexico in search of a divine sign to indicate the precise spot upon which they were to build their capital. Their god Huitzilopochtli had commanded them to find an eagle devouring a snake, perched atop a cactus that grew on a rock submerged in a lake. After 200 years of wandering, they found the promised sign on a small island in the swampy Lake Texcoco. There they founded their new capital, Tenochtitlan. The cactus ( O. ficus-indica; Nahuatl: tenochtli), full of fruits, is the symbol for the island of Tenochtitlan.
Israeli-born Jews
The cactus fig is called tzabar in Hebrew (). This cactus is also the origin of the term sabra used to describe any Israeli Jews. The allusion is to a thorny, spiky skin on the outside, but a soft, sweet interior, suggesting, though the sabras are rough on the outside, they are sweet and sensitive once one gets to know them. This term is derived from the related Arabic word for this cactus صبار ṣubbār, where the related term sabr also translates to "patience" or "tenacity".
Palestinians
The prickly pear is also considered a national symbol of Palestine, having been grown across historic Palestine for centuries, traditionally being used to mark out land boundaries. The plant is seen by Palestinians as representing qualities of resilience and patience, as represented by the Palestinian proverb saber as-sabbar ("the patience of the cactus"). Its use as an emblem of Palestine has been traced to a painting produced by the artist Zulfa al-Sa'di in the 1930s. Its visibility was renewed by historical research carried out in the 1980s and 1990s on the Nakba, which revealed that many destroyed Palestinian villages subsequently saw regrowth of the cacti. The plant's ability to thrive anywhere is also considered to reflect the experiences of the Palestinian diaspora.
