Opuntia
Named for the Greek word "opsis," meaning "appearance," and referring to its resemblance to a specific flowering plant, larkspur (Delphinium), opuntia is a genus of more than 100 species of cacti. The pale green stem segments on some species fold up at night or in cloudy weather, unlike most other cacti, which usually fold up only during the heat of the day. There are many hybrids and cultivars, and some species have yellow, pink, red, or purple flowers. The size and shape of the fruit vary widely among opuntia species: Some look like lollipops; others resemble cornichons or gherkins.
The name prickly pear refers to any one of a number of cactus species including opuntia that have glochids, small bristles with one or more fine spines on the tip, such as the claret cup and Indian fig opuntias.
Native to North America and Asia, prickly pear species are cultivated around the world in warm regions where they make attractive house plants. Historically used by natives of the southwest United States and Mexico, prickly pear cactus fruit is edible, although most species are not sweet enough to be considered palatable.
The term "prickly pear" refers to a large number of opuntia species or hybrids/cultivars that have flat joints along a thick green stem called a cladode, with small spines on the end. The stem joints are known as cladodes, singular: cladode. Prickly pear species grow into different shapes and sizes, but most are columnar, rounded cacti that can reach over 5 meters tall. Unlike some other types of cacti, prickly pears never have spineless varieties but are covered with clusters of spines. Although they are called "prickly pears", almost all species have leaves that can be pulled off to reveal glochid-barbed spines in their place. The stems grow one on top of the other when new growth is formed in the axils of the previous stem. All species of opuntia have flat oval seeds that require extensive dispersal distances to ensure genetic drift from others of its kind.
The glochids often fall off the plant as it moves from location to location, and are a form of very effective adaptation to seed distribution by both attaching themselves to animals and being easily spread in their manure
Opuntia produce flowers that are usually yellow or orange and sometimes brownish or reddish. Because Opuntia leaves are partly photosynthetic, flower colors range from green to white depending on climate and soil conditions. Opuntia flowers may be single or appear in clusters.
Global opuntia cactus production
The fruit of the opuntia cactus is a popular food item around the world. Mexico is the largest producer of this fruit, followed by Peru, Chile, and the United States. The fruit is often used in salads or as a topping for desserts. It can also be made into jams and jellies.
The opuntia cactus is native to Mexico and the southwestern United States. It has been introduced to other parts of the world, including Europe, Australia, and Asia. The cactus can grow to be over 20 feet tall and is covered in spines. The fruit grows on the pads of the cactus and is oval-shaped with a red or yellowish-orange color.
The opuntia fruit is high in antioxidants and vitamins A and C. It also contains a type of soluble fiber that can help to lower cholesterol levels. The fruit has a sweetness to it and a slightly tart flavor.
The production of opuntia fruit has increased in recent years due to the growing popularity of the fruit. The majority of the fruit is still grown in Mexico, but other countries are beginning to grow more of it as well. The United States is the fourth largest producer of opuntia fruit.
The opuntia cactus is a hardy plant that can tolerate a wide range of climates. It grows best in areas that receive full sun and have well-drained soil. The cactus can be propagated by seeds or cuttings.
