There is only one native cactus plant in South Africa, the Rhipsalis baccifera, despite the country’s profusion of native succulents. Instead of genuine spikes, it possesses clumps of harmless fuzzy spines. Its tasty white (or occasionally pink or red) berries give it the nickname “mistletoe cactus” since it resembles mistletoe in appearance.
No cacti are indigenous to Egypt, with the exception of the Rhipsalis baccifera, which is found in subtropical areas of Africa. Other places of the world, including Central America, are home to this cactus species.
Are there cactus in Africa?
Cactus, often known as cacti or cactuses, belongs to the order Caryophyllales and is a family of flowering plants with about 2,000 species and 139 genera. From British Columbia and Alberta southward, cacti are native to most of North and South America; the southernmost portion of their distribution reaches deep into Chile and Argentina. The highest number and variety of species are found in Mexico. The only cactus that might be native to the Old World are Rhipsalis species, which are found in Sri Lanka, Madagascar, and East Africa. Few cactus species exist in tropical or subtropical climes, although the majority do and are well adapted to dry conditions. List of Cactaceae plants is also available.
Are there cactus in the deserts of Africa?
Here are several examples:
The African Peyote Cactus thrives in arid climates. Long-lasting water retention is provided by its thick stems. Its spiky leaves aid in preventing evaporation-related water loss. Peyote from this plant is used by local Saharan tribes in
their sacramental practices. The African peyote cactus only relies on the water it stores in its thick stem after each rainstorm to survive till the next one. It requires very little sunlight to survive and prefers PH 6 or 7 soil. Seeds or the shoots of an established plant might be used to start the plant.
Palm trees typically flourish in regions where the water is nearer the land’s surface. These particular trees are oriented from east to west and are organized in short lines. The desert palm grows around towns where people drill wells to obtain water.
A significant tree that thrives in numerous locations along the Nile River in North Africa is the olive tree. This tree is grown for its oil, which is used in cooking. The olive tree’s thin leaves have a protective layer that prevents water loss, allowing it to thrive in the hot, dry conditions.
The poisonous tobacco tree is a native of South America, but it has adapted to life there. The white, green, red, or yellow flowers on this tree may bloom at night. You might believe that this tree’s leaves can be smoked, but that is untrue. Dizziness and impaired eyesight are symptoms of poisoning. Another side effect of the tobacco tree is auditory hallucinations.
Tamarisk (Shrub) is a saline or alkaline-loving plant that can reach heights of up to 18 meters. It frequently serves as shade and is utilized for carpentry and firewood. Tamarisk can also block the wind. It features racemes of white, pink, or red flowers as well as small, scale-like leaves. It also has tiny, slender branches and broad, deep roots.
A dioecious shrub with densely branching, upright stems is called ephedra alata. It produces flowers with four to six anthers and very small leaves. This plant’s alkaloids are responsible for much of its action. There are numerous medical uses for its plants.
Which nations can you find cacti in?
Numerous kinds of blooming plants with succulent (water-storing) stems belong to the family Cactaceae. Cacti are unique among all other plants due to the existence of an organ called the areole. Flowers, new branches, and spines emerge from areoles. Spines come in a variety of shapes and sizes; some are delicate and feathery to shield the plant from harsh sunlight, while others are strong and spiky to provide protection. The spines on cacti restrict animals from getting to their water supply, even though they may be one of the few sources of water in arid areas. Cacti have a waxy covering called a cuticle that serves as a barrier against water loss. They also use stomata, which open at night instead of during the day like other plants do, to conserve water. The plant’s stomata are tiny pores that allow carbon dioxide to enter for photosynthesis.
The size of cacti varies according on the species. Blossfeldia liliputana, a South American plant with a mature diameter of less than an inch (2.5 centimeters), may be the smallest cacti species. The Mexican enormous cardon, which is almost 60 feet tall, is the tallest cactus (18 meters).
The majority of cacti genera originated in the Americas and can be found from Canada to Chile. They are now widespread around the world, particularly in Australia, South Africa, and nations in the Mediterranean.
Some people mistakenly believe that cacti are only found in the desert, yet many species, like the prickly pear cactus, may be found in a variety of settings.
Cacti are seed-producing blooming plants. They are able to bloom every year, but when it rains a lot, they will produce a lot of flowers. Different flowers have different looks and smells to draw different pollinators, like insects and bats. Cacti grow slowly and have a long lifespan. Saguaro cacti, for instance, can survive for up to 175 years. Between the ages of 75 and 100, they do not develop their first arms.
Populations of cacti are generally stable. However, some species are diminishing as a result of being taken out of the wild and planted on xeriscaped lawns as decorative plants (landscaped areas that require little or no irrigation).
Most cacti have root systems that stretch out near the ground to absorb as much precipitation as they can. Some species can survive several years of drought because they are adept at storing water.
Do cacti grow in the Sahara?
Life of every type can be found in the Sahara and its oases and plateaus. Beyond the vegetation mentioned above, you can anticipate to see figs, oranges, acacia trees, tobacco plants, oleander, peyote cacti, and a great deal more.
Can you find cactus in South Africa?
EVEN though South Africa is home to several native succulents, there is only one native cactus.
Additionally, this plant doesn’t resemble a cactus in the least bit. Elsa Pooley’s Guide to Wild Flowers of KwaZulu-Natal and the Eastern Region describes it as a straggling pendulous epiphytic succulent under the name Rhipsalis baccifera. It only has clumps of innocuous fuzzy spines rather than actual spikes. It resembles mistletoe somewhat thanks to its luscious white (sometimes pink or red) berries, which is presumably how it got its common name, mistletoe cactus.
We do observe a lot of alien cacti growing in the wild in this nation, including different prickly pear species like Opuntia ficus-indica and Opuntia monacantha. Many of these cacti have developed into unruly weeds. Except for the spineless horticultural variants, both of these plants are categorized as invaders, according to Richard Boon’s book Pooley’s Trees of Eastern South Africa. It’s great to hear that non-invasive versions have been created because they are incredibly valuable plants. Their delicious fruit is used to create a variety of goods, including jams and alcoholic beverages.
They are also utilized as hedging and as feed. Richard claims that the cochineal insects that consume Opuntia species are the ones that produce the cochineal or carmine dye that is used to color food, cosmetics, and clothing.
The good news is that utilizing biocontrol chemicals to stop the spread of invasive prickly pear species has worked well for conservationists.
The invasive Cereus jamacaru, often known as the “queen of the night,” is a beautiful plant with big white blooms that bloom at night and has been added to South Africa’s list of undesirable plants. It should not be grown because it has unfortunately become invasive.
Some of the Euphorbia family members, such as the Euphorbia ingens, also referred to as the naboom, are endemic to South Africa and resemble cactuses the most.
They are widely dispersed in the northern savannahs, according to Gideon F. Smith and Neil R. Crouch’s “Guide to Succulents of Southern Africa.” Euphorbia tetragona, sometimes known as honey euphorbia, is another common and attractive member of this species. This species can be found in the KwaZulu-Natal and Eastern Cape valleys, where it develops into a strong tree similar to the naboom. Not every euphorbia grows to be a size of a giant cactus. Euphorbia pulvina, which hugs the ground, resembles an overgrown pincushion. The dwarf succulent Euphorbia Woodii is described as having a “Medusa-like head growing prostrate on the soil surface” in the succulent guide.
Our larger, tree-like aloes make excellent cactus substitutes. The beautiful Bulbine, Gasteria, and Haworthia species, among other eye-catching relatives, are highly prized by enthusiasts of succulent plants.
There are numerous additional succulent families in southern Africa, the majority of which make excellent, water-wise, intriguing, and attractive garden topics. Of course, the Baobab (Adonsonia digitata), which can develop into a vast, enormous-girthed tree, is our largest succulent native to southern Africa.
The writers of the succulent guide note that plants like succulents that must endure times of intense stress typically are rich in compounds that frequently have medical uses. People in southern Africa have traditionally used succulents as a form of medicine.
They can be used for a variety of other things. Some are sold as traditional medicines, some are utilized as food, and some serve as a source of fiber for weaving and making ropes. The two writers argue that succulents are becoming more and more important in the effort to provide enough food for our expanding southern African population as well as sustainable plant material for use in traditional medical treatments.
Cacti grow in Egypt, right?
Thus, cactus are not visible in Egypt. If so, they were likely brought in by men and preserved in pots. Except for the Rhipsalis Baccifera, which grows in subtropical parts of Africa, there are no native cacti to Egypt. Additionally, this cactus species can also be found in the Americas. Therefore, it is disputed if they are indigenous to Egypt alone.

Do cacti grow in all deserts?
It’s been seen a gazillion times. While struggling across the scorching sands in search of water, shelter, or simply any way to escape the intense sun, the hero and his comic relief sidekick stroll right past a gigantic saguaro cactus. They’re advancing through Arabia’s deserts, which is a concern.
Cacti are seen in every desert in fiction. And typically not just any cactus, but the traditional saguaro with two arms (though barrel- and beavertail cacti are also popular). Forget the fact that cacti are exclusively found in the New World. There are only bushes, dunes, and bare rock in the Sahara. For instance, the saguaro is only present in southern Arizona, northwest Mexico, and a very small portion of California. In fact, the entire Cactaceae family is indigenous to just the Americas, including high-altitude and frigid regions. Of course, there are a variety of cactus species that can be found in fantastical realms, but placing them all over Arabia, Africa, and Australia is foolish (granted, they have been cultivated abroad for ornamentation and fruit, particularly the Pitaya, but seeing them in the wild outside the Americas is right out).
There is no better way to show that you are in a hot desert than to include a cactus. Many people have heard of Peyote, but few are aware that it is a cactus. That is, until someone on television is stuck in the desert and starts to become thirsty. Then they recall that cacti are full of water… And Knowing Is Half the Battle.
An alternative stereotype holds that all deserts, with the exception of cacti, are sandy wastelands, completely ignoring the fact that, aside from Antarctica, all deserts have vibrant ecosystems with their own distinct animal and plant life. The most well-known cacti are Aloes, which are indigenous to Southern Africa and some regions of Arabia. The part regarding sand is particularly overstated because rocky deserts, like those where cactus naturally flourish, are more common than sandy deserts.
Additionally, as previously implied, Antarctica is in fact a desert since the fundamental definition of a desert is a region with very little precipitation, often known as little rain or snow. Even though it is a frigid desert, it is the biggest desert in the planet.
Which deserts are home to cacti?
Rain forests and even Canada’s far north are home to cacti. However, their most amazing characteristic is their capacity to flourish in the desert, where rain occurs sporadically and erratically.
By working evenings, finding alternate ways to get energy, and maintaining a bag of sour tricks.
The cactus have developed a wide range of adaptations to live in the desert, according to Erika Edwards, a plant evolutionary researcher.
The saguaro, or Carnegiea gigantea, is one of the most recognizable cacti. However, they only flourish in the Sonoran Desert, where they can be seen growing tall in a small area of southern Arizona, northern Mexico, and southeastern California.
According to research by Edwards and Michael Donoghue of Yale University, leafy shrubs and trees of the Pereskia genus originally exhibited some of these water-saving characteristics over 20 million years ago.
The journal American Naturalist reported the findings in its June issue.
Stomata are tiny skin pores that open and close on all plants to capture carbon dioxide. Plants convert the carbon dioxide they have gathered into nourishment in the form of carbohydrates during photosynthesis. Water escapes from the pores every time they open, making the process challenging in the desert.
It’s hazardous business to open the pores and lose water if you’re attempting to conserve water, Edwards told LiveScience.
Cacti and other nocturnal plants, including agaves and aloes, open their pores at night while most plants open their stomata during the day.
Cacti are able to hold onto water because of the cooler temperatures, lack of sunlight, and quieter breezes.
In order to thrive in their harsh environments, cacti have also evolved succulent tissue, waxy skin, prickly spines, and a unique root system.
- The stem serves as a reservoir, and depending on how much water it contains, the plant will grow and shrink.
- The waxy layer of the skin keeps moisture in.
- The sharp spines defend against animals asking for a free sip out of thirst.
Some cacti have spines that also catch raindrops and deliver the valuable liquid to the plant’s roots.
You might imagine that cactus would develop extensive root systems to look for a steady source of groundwater. Instead, they frequently form large, shallow root systems that reach several feet away from the plant, sit just below the Earth’s surface, and are ready to collect as much water as possible.
Cacti grow additional roots when it rains. To conserve the plant’s water supply during dry times, roots will shrink and split off.
According to Edwards, “the cactus becomes more hydrated than the soil it is growing in.” It must cut its connection to the soil since it faces the risk of losing water to the soil.
Even lacking the morphological peculiarities of the typical leafless cacti, leafy cacti like the Pereskia and other plants have evolved comparable water-saving features and reside in the desert.
It’s solid proof that the tactic is effective, according to Edwards. “The plants thrive very well in these conditions.”
