Native or Immigrant? The prickly pear’s identity crisis
This is the bloom from which a prickly pear will grow. A couple more full fruits develop below the blossom, and a young fruit is already seen growing beneath it.
Israel and the Middle East as a whole are covered in prickly pear cacti, which are utilized as borders between towns and villages as well as to grow the wonderful fruit. Since cacti are so common, many people believe that prickly pears originated in the Middle East. Israelies have gone one step further and started referring to native Israelis by their Hebrew word for the prickly pear, tzabar, or Sabra in English. A tzabar is said to be soft and delicious on the inside yet prickly and hazardous on the outside, just like the fruit.
However, the prickly pear might perhaps be a fake. Although it acts native, it is actually a recent immigrant (in Hebrew, an oleh). Molecular DNA research revealed that the Middle Eastern prickly pear, Opuntia ficus-indica, is actually a Mexican import! Prickly pear cactus were widely dispersed over the Mediterranean by European traders when they carried them on board to stave off scurvy.
Do cactus grow in Africa?
A cactus is a member of the plant family Cactaceae[a], which has about 127 genera and about 1750 recognized species. Cactaceae belongs to the order Caryophyllales.
[4] The Latin word “cactus” is derived from the Ancient Greek word “kktos,” which Theophrastus first used to refer to a spiky plant whose identify is currently unknown. [5] There are many different sizes and shapes of cacti. Most cactus reside in settings that experience at least some drought, despite the fact that some species can tolerate fairly humid situations. Many of them can even be found in the Atacama Desert, one of the driest places on Earth, where they exist in extremely dry circumstances. Cacti have developed a variety of adaptations to conserve water as a result. As an illustration, nearly all cacti are succulents, which means that their swollen, fleshy sections are designed to store water. Unlike many other succulents, most cacti only have a stem where this crucial process occurs. The majority of cacti species no longer have actual leaves; instead, they only have spines, which are heavily modified leaves. Spines help limit water loss by slowing air movement around the cactus and offering some shade, in addition to protecting it from herbivores. Photosynthesis is performed by cacti’s expanded stems in the lack of real leaves. Except for Rhipsalis baccifera, which also grows in Africa and Sri Lanka, all of the Americas, from Patagonia in the south to sections of western Canada in the north, are home to cacti.
Areoles, a type of greatly shortened branch, are specialized structures that create cactus spines. Cacti can be identified by their areoles. Areoles also produce multipetalled, tubular blooms in addition to spines. Because many cacti have extended dormant periods and short growing seasons, they may respond fast to any rainfall. This is made possible by their large but shallow root systems, which swiftly absorb any water that reaches the ground surface. Because cactus stems are frequently ribbed or fluted, they can easily stretch and contract to quickly absorb water after rain and then hold onto it during protracted droughts. The majority of cacti use a unique process called “crassulacean acid metabolism” (CAM) as part of photosynthesis, similar to other succulent plants. Unlike photosynthesis, which occurs during the day, transpiration—during which carbon dioxide enters the plant and water escapes—occurs at night. The plant converts the carbon dioxide it absorbs into malic acid and stores it there until daybreak, when it is solely used for photosynthesis. The cooler, more humid nighttime hours are when transpiration occurs, which greatly reduces water loss.
The globe-shaped stems of many smaller cacti combine the maximum volume of water storage with the smallest surface area of transpiration loss. The largest[b] free-standing cactus is Pachycereus pringlei, which reaches a maximum height of 19.2 m (63 ft)[7], while Blossfeldia liliputiana has the lowest diameter at maturity, measuring just around 1 cm (0.4 in). [8] During a downpour, a mature saguaro (Carnegiea gigantea) is believed to be capable of soaking up 200 US gallons (760 l; 170 imp gal) of water. [9] Only a few species look significantly like the rest of the family. Plants belonging to the genera Leuenbergeria, Rhodocactus, and Pereskia resemble nearby trees and bushes, at least on the surface. They have enduring leaves and, as they age, stems covered with bark. Despite their appearance, they are recognized as cacti by their areoles and have numerous water-saving adaptations. Leuenbergeria is thought to be very closely related to the original species from which all cacti descended. Other cacti develop as forest climbers and epiphytes in tropical areas (plants that grow on trees). Their stems often have fewer or even no spines and are flattened, almost leaf-like in appearance, like the well-known Christmas or Thanksgiving cactus (in the genus Schlumbergera).
Many types of cacti are produced as beautiful plants, while others are raised for fodder or forage, and yet others are utilized as food (particularly their fruit). An bug that lives on some cactus produces cochineal.
Many succulent plants, both in the Old and New Worlds, have spiky stems, including some members of the Euphorbiaceae (euphorbias), which is why they are frequently mistakenly called “cactus.”

Does the Arabian desert have cacti?
The Arabian Desert is the second-largest desert in the world, measuring 899,618 square miles. It is 1,305 miles long from east to west and 684 miles long from north to south. The Arabian Desert runs from the Persian Gulf to Yemen, from Oman to Jordan, and from Iraq to virtually the entire Arabian peninsula.
It spreads across a significant portion of Saudi Arabia and simultaneously into other nations including Yemen, Egypt, Iraq, Bahrain, the United Arab Emirates, and Jordan. The Nile Valley, the Red Sea, and the Gulf of Suez all abut the desert on its western and eastern sides, respectively.
The largest sand desert in the world, the “Rub al Khali,” is located in the middle of the Arabian desert, which serves as an excellent way to highlight its enormity. The Rub’ al Khali, sometimes known as the “Empty Quarter,” covers a 250,000 square mile area that includes parts of Saudi Arabia, Oman, the United Arab Emirates, and Yemen.
The Arabian Desert has a hyper-arid climate, which is characterized by high dryness and rapid temperature swings. In this area, the yearly rainfall rarely surpasses 35 mm. The daytime temperatures are extremely high, while the evenings are bitterly chilly. In the summer, the temperature ranges from 104 to 122 F, and in the winter, it is between 41 and 59 F. It is also occasionally known for the temperature to fall below zero, which renders the environment harsh and unfit for human habitation.
Despite being harsh, the Arabian Desert does not prevent several plant and animal species from residing there. The ability to live with little water is definitely the most important plant adaptation in this area due to the infrequent rainfall. While plants survive by storing the water that is available in their fatty tissues, herbivores obtain water from plants when they consume them.
The biodiversity of the Arabian Desert may not compare to that of the Amazon rainforests, but it does contain a number of species, some of which are endemic to this area. Arachnids like the camel spider and fat-tailed scorpion live in the Arabian Desert in addition to insects like beetles, butterflies, and moths. It also has a variety of reptiles, including Arabian cobras and monitor lizards as well as spiny-tailed lizards and spiny-tailed lizards.
The sand grouse and lanner falcon are two of the most well-known birds in this desert. In a similar vein, this region has also had sightings of the endangered houbara bustard. Jerboa, gazelles, Arabian oryx, sand cats, Arabian wolves, red fox, caracal, and last but not least, the dromedary camel are among the creatures that inhabit the Arabian desert.
All of these animals have developed behavioral adaptations to the harsh conditions of the Arabian peninsula, such as living in burrows, remaining active only after dusk, getting their water from food, storing it in their fatty tissues, and physical adaptations, such as having long ears to dissipate heat and a thick outer layer to prevent moisture loss.
Jerboas pride themselves on being one of the animal kingdom’s most adaptable species, and their diverse habitats more than prove it. These hopping rodents can survive in both hot and cold deserts because to a number of odd adaptations. Speaking of adaptations, the lesser Egyptian jerboa, which may be found in the Arabic Desert, plugs the entrance of its burrow with sand to seal it off, keeping moisture within and hot air outside. And that is merely one of the numerous adaptations that have allowed this animal to endure in the Arabic Desert.
The flora have also adapted to this severe environment, much like the animals have. Ephemerals, succulent perennials, and woody perennials make up the majority of the vegetation found in the Arabian Desert. Long roots, short spiky shoots, fleshy or needle-like leaves, which together assist the plants adapt to the severe circumstances of the Arabian Desert, are typical characteristics of the majority of plant species.
The date palm, caper, ghaf, myrrh tree, juniper, and other plant species are some of the most prevalent ones found in the Arabian desert. Similar to this, calligonum crinitum and calligonum comosum are common plant species in this area. Date palms, which are famous for their delectable edible fruits, are by far the most well-known of the diverse plant species that can be found in this desert.
The Arabian Desert does not contain any cacti species, as we previously stated. However, it’s possible that you’ll run into certain imported cactus species that are either grown for landscaping purposes or commercially for their fruits. The prickly pear cactus, which is renowned for its fruits that taste like raspberries, is one of the best examples of such invasive plants.
Rich natural supplies of gas and oil are also found in the Arabian Desert. In 1936, oil reserves in this area of eastern Saudi Arabia were first discovered. Millions of barrels of oil are now produced each day by the oil refineries in this area. In actuality, it is this particular aspect that has positioned this region in the epicenter of the current political tempest.
Production of oil and gas undoubtedly helped this area to expand, but it also left a significant amount of harm in its wake. Recent human activities, including as farming, domestic animal overgrazing, off-road driving, conflict, etc., have resulted in widespread habitat loss in the Arabian Desert. If conservation measures are not put into place immediately, the issue will only get worse and eventually have negative repercussions on the ecology.
What is the fabled Egyptian plant?
In the ponds of the Nile Delta, papyrus flourishes. Its iconic blossom is carried by tall stalks that have deep mud-dwelling roots. Paper for writing is produced from papyrus. The blossoms of the evergreen papyrus plant were offered to the gods in the Pharaonic temples.
What plant is most prevalent in Egypt?
Perhaps the first nation to identify its national flowers and plants was Ancient Egypt. These were the Papyrus and Lotus, which stood for Upper and Lower Egypt, respectively. The national flower of Egypt is currently the pure white Egyptian lotus flower, which is the only plant to bear fruit and bloom at the same time. It is also known as the Water Lily, a flower that grows in water.
Other native and popular flowers of Egypt
The Nile Valley is a densely populated area with a climate that is ideal for flower cultivation. In fact, Egypt exports a wide variety of flowers these days, and Egyptians have always loved flowers and have done so since antiquity. Rosa richardii, Egyptian lotus, Immortelle, Lychnis, Jasmine, Narcissus bulbs, Acacia, Sesban, Epilobium hirsutum, Chrysanthemum, Cornflower, Red poppy, Arum, Dragonwort, Iris albicans, Papyrus, Crinum, and the little Marjoram bush are some of the most well-known flowers found in Egypt.
If they pay attention, many first-time tourists to Egypt frequently find the abundance of flower shops to be startling. It is because Egyptians are so passionate about flowers. Since the beginning of time, people have used flowers as a symbol of expression. They commonly give and receive gifts of water lilies, roses, iris, chrysanthemums, and cornflowers.
Does Dubai have any cacti?
In the United Arab Emirates, cacti and euphorbias are some of the least difficult and demanding plants to grow.
Succulents are among the least difficult and least demanding plants to grow in the UAE. The Latin word succulentus, which means “juicy sap,” is used to describe these plants because they have fleshy leaves, stems, or roots that can store water, making them especially suited to a desert environment.
Cacti are among the most well-liked succulents. The word “cactus,” which refers to the spiky spines covering the succulent stem of a cactus, is derived from the Greek word “kaktos,” which also means thistle. Cacti can be separated from other succulents, which also have spines, by having areoles, which are pad-like buds from which new blooms, shoots, or spines emerge.
Either along the ribs of columnar or barrel cacti, or at evenly spaced intervals over the face of pad-like cactus, the areoles are arranged in a regular pattern.
The Euphorbia family of plants is one that is sometimes mistaken for the cactus family. Cow’s Horn Cactus, African Milk Bush, and Crown of Thorns are examples of euphorbias that lack areoles but have spines, green stems, and few leaves. Make a small cut in the stem to determine whether your plant is a euphorbia or cactus. You have a euphorbia if the sap is milky white and sticky; a cactus if the sap is clear and watery.
Euphorbias and cacti both feature lovely, vividly colored flowers and come in a variety of intriguing shapes and sizes. The perfect plants for a rock garden are cacti and other succulents, such the rosette-shaped spiky Agave, Aloe, and jade with its small, fleshy leaves.
On a sunny windowsill, smaller succulents like peperomias and cacti can be cultivated indoors. Creative plant arrangements may be created using a variety of miniature succulents in a variety of colors and forms. These arrangements require very little maintenance and last a lifetime.
While most succulents do best in regions with lots of sunlight, some prefer semi-shade and make excellent patio plants. Succulents are advantageous since they keep their green color all year long. Consider its location away from sprinklers and other plants that need frequent watering if you’re planning a rockery with cacti and other succulents.
It’s a frequent myth that cacti can endure in sand. A mixture of two parts peat-based potting soil and one part coarse sand works best for growing cacti, however some species can. Waterlogging will result in rotting of the roots, which will ultimately destroy the plant, so good drainage is crucial. To reduce the chance that the soil in the lower layers will remain wet, use shallow pots.
Cuttings are a common method of propagating succulents. Make a cut at a joint using a tidy, acute knife. To prevent the cut edge from rotting from fungal infections, it is best to let it remain in a warm, dry location for a few days before planting it in soil. Be careful when planting because cuttings from many succulents and all cacti won’t grow if they are placed upside down. From the mother plant, many cacti produce young plants. You may plant each one independently.
Agaves typically only bloom once until they reach maturity, which could take up to 60 years for species like the Century Plant. Strong, more than six-foot tall spikes that sprout from a fleshy rosette of leaves carry the vividly colored flowers. The mother plant perishes once the seeds are disseminated.
You must have noticed the little flowering cactus that are here in containers at nurseries. The flowers are fake, but the cacti and spines are real.
Simply dried flowers that have been adhered to the plants. They make excellent, low-maintenance indoor decorations. Put a few of these together on a center table in painted ceramic pots, hollow crystal objects, or candle holders to brighten the space.
They only require a change of soil once a year and 10 drops of water once a week. In particular, if they are in pots without a drainage hole, be careful not to overwater them.
Avoid purchasing any cactus that have broken spines, apparent bruises, or asymmetrical or uneven growth.
– Succulents require watering every three to seven days, depending on their size and exposure to sunlight, but you should always consider each plant’s specific requirements.
Cacti in the UAE frequently become dormant over the winter and begin to develop again in April. They simply need to be watered once every two weeks or once a month during the dormant stage. Weekly watering is necessary in the summer.
– Never overwater a succulent, and check that the pot’s drainage hole is not plugged. Before watering the plant again, you should ideally wait a few days for the soil to dry out.
– When repotting and pruning cacti, always wear heavy gardening gloves, or wrap them in newspaper. Since many euphorbias have toxic sap, wash your hands thoroughly afterward.
– Cactus buds need to be cut back frequently. Some cacti have a tendency to spread rapidly; these should be moved to larger pots.
Succulents don’t require a lot of fertilizer. In the summer, diluted doses may be administered once a month. Beware of fungal infections brought on by excessive watering. Once a year, small pesticide doses can be used.
– The sap of succulent plants, like Aloe vera, can be used as a conditioner for dry hair as well as a soother for sunburned skin.
– Ropes and baskets are made from the sisal fiber that is derived from some Agave types.
– For millennia, American Indians have utilized the sap from specific cacti to heal snake and pest stings. Additionally, they add the prickly pear cactus pads to salads and baked goods.
– To make fish easier to remove out of streams by hand, some Indian tribes apply the poisonous sap of Stenocereus gummosus.
The Opuntia coccenillifera cactus was cultivated by the Aztecs because it attracts cochineal insects, whose scales were crushed to make a purple dye from the females and a red pigment known as cochineal from the males.
