A peculiar plant is the cactus. It can withstand high temperatures since it can hold a lot of water. Cacti are primarily found in the hot, dry climates of South and North America. Cacti come in approximately 2000 different species. Cactus, on the other hand, has become an incredibly popular house and garden plant all over the world since it is a highly appealing plant that comes in a variety of shapes, sizes, and colors. Therefore, overfishing and habitat loss are major threats to cacti’s ability to survive in the wild. As a result, several species are classified as endangered, and commerce in the majority of cacti species is prohibited by law.
Variety of Shapes And Sizes
- Depending on the species, a cactus’ life cycle might last anywhere from 15 to 300 years.
- Cacti exist in a wide range of sizes. When completely filled with water, one of the largest species can reach heights of 66 feet (20 meters) and weigh up to 4800 pounds (2177 kilograms). The smallest species are typically little taller than a few inches.
- Cacti are adapted to life in arid climates. As a result, they have a large capacity for water storage, which they do by storing it in their stems and roots. Stems are utilized for photosynthesis, a process that turns carbon dioxide and sunlight into food, in addition to water storage.
- Even though the cactus’ roots are only a few inches deep, they can grow up to seven feet (2.1 meters) in diameter. Since water may easily travel through the sand, cactus concentrate on having roots that are thin and shallow in order to collect as much water as they can.
- Cacti can be shaped like a starfish, a tree, a cylinder, or something else entirely. They might have ridges or a flat surface.
- Cacti can be green, brown-green, or blue-green in color. Cactus develops a waxy coating on a surface that stops water loss through transpiration (evaporating of the water through small holes during high-temperature periods).
Cactus Fact #1: The Thorns are Actually Spines
What we typically think of as thorns on cacti are actually spines, which are actual plant parts, specifically leaves. That’s how it used to be, at least. Spines have grown from this during the course of evolution, ensuring the cacti’s survival even in the harshest environments.
Phytochemically, “spines are distinct from “thorns: spines are modified leaves, and thorns are modified branches, according to Wikipedia.
Cactus Fact #2: The Spines are Weapons, Sun Protection, Drinking Straw and Coat
Cacti would literally be discovered as food for animals in their arid surroundings. This is avoided by their spines. They are capable of much more, such as shielding the plant from sunburn by reflecting sunlight. However, during chilly nights, they keep out the cold. The cactus can absorb the water that forms when mist clouds condense on their spines. Additionally, they become entangled in the fur of nearby animals. They split out in other places, where a new cactus can emerge. Consequently, they assist in the spread as well.
Cactus Fact #4: You Can Eat Them
The orange-red fruits of the prickly pear, which belong to the genus Opuntia, are available in every delicatessen. However, the plant’s green sections are also edible. They become a sour, flavorful vegetable when steamed or fried. The world’s oldest cactus farm, which has been around in Erfurt since 1685, demonstrates what may be created from the prickly plants and served as food.
Cactus Fact #5: One Can Get Intoxicated with Them
Three thousand years ago, the Native Americans learned that some cactus species were intoxicating. They chewed on plant fragments because they thought it would bring them closer to the gods. The peyote cactus, which contains mescaline, is unquestionably the most well-known. In 1888, Louis Lewin was the first to approach this phenomenon scientifically. He was able to extract “anhalonin” after looking at the peyote cactus. Arthur Heffter succeeded in isolating pure mescaline in 1896. In 1919, Ernst Spth completed the first total synthesis. He thereby established the framework for the drug’s synthetic manufacture. The UN Convention has deemed it unlawful everywhere since 1971. Possession of mescaline carries a maximum five-year jail sentence in the USA.
Cactus Fact #6: You Can’t Drink It
Adventure writers are responsible for the notion that a cactus can relieve a desert traveler’s thirst. When you cut open a cactus, all you find is a thick gel that is poisonous. It is equally impossible to remove water from it on-site as it is to do so with shower gel.
Cactus Fact #7: You Can Make Furniture Out of Them
Over time, the cacti’s woody parts can develop. Particularly column cacti produce enormous woody pieces. The benefits of this cactus wood are numerous: It grew quite straight and is free of knotholes. Its fiber structure, which is broken up by cavities, makes it both flexible and incredibly stable. This wood has only so far been used to make furniture in Latin America. You can get creatures like birds and reptiles toys in this nation.
What makes cacti special?
Cacti are perennial succulent plants. Typically, cacti have thick, woody, or herbaceous stems that contain chlorophyll. Areoles—small cushion-like structures containing trichomes (plant hairs) and, in nearly all species, spines or barbed bristles—distinguish cacti from other succulent plants (glochids). Areoles are modified branches that can develop into flowers, other branches, and leaves (if any are present).
What feature of a cactus is most significant?
Every plant has leaves, which are crucial to its ability to produce the food needed for growth and life. If you’ve ever been in close proximity to a cactus plant, you might be curious about how it manages to survive without leaves.
A cactus plant contains spines rather than leaves as a strategy for the plant to survive. There are several different types of spines, including:
- Awl-like
- Straight
- Curved
- Needle-like
- like a bristle
- Hair-like
- Round
- Hooked
The cactus plant prefers the spiky protrusions over leaves for several very significant reasons. The following functions of spines in a cactus plant are listed.
Protection
Numerous herbivores in the desert rely on various desert plants for food, and cacti are no exception. The plant’s mushy appearance is bound to draw various creatures, which is where the spines come into play.
Poachers pose a harm to flora in addition to animals. Cactus trade on the illegal market is lucrative and results in the eradication of the plants. If the cactus is repeatedly destroyed, it can go extinct.
The plant uses its spines as a form of protection. Upon close contact, the needles thoroughly pierce the flesh. Any animal can only imagine how excruciatingly painful a spine puncture is.
After being punctured, the spines are difficult to remove from the skin and could result in subsequent infections. Some spines have the potential to inflict several wounds at once.
Water collection
This is how spines assist in water collection in misty deserts. The fog becomes the water that eventually trickles down onto the earth below as it touches the spines. The plant then stores this water in its roots for later use.
Air trapping
Spines help break up the passage of air around a cactus plant, which can cause water loss. The plants would otherwise lose a lot of water due to excessive water evaporation in the absence of the buffer that the spines provide.
Shade
The spines collectively offer shade in the desert’s sweltering heat. The absence of shade would prevent the plants from surviving because the desert heat would quickly dry out all of their moisture.
Propagation
The growth of new plants in the same species depends on propagation. Strong desert winds frequently move the spines that penetrate animals or are blown around by those spines. After that, the spines develop into cacti plants, ensuring that the plants live on after the older ones pass away from aging.
How long are cacti alive?
Carefully! To loop around the top, use either very thick gloves or folded newspaper. With tweezers, you may remove huge spikes that have stuck you. Small spikes can be removed by covering them with duct tape, ripping it off, or quickly massaging the area with a ball of old tights. The experts at Thejoyofplants.co.uk suggest using olive oil to refine the final fine spikes.
What pests do you need to look out for?
Verify that the plant’s body (the cactus’ “body”) and the root system are devoid of mealybugs. It is one of the most prevalent and challenging cactus pests, with a fuzzy white wax coating that contains oval insects. Additionally, aphids, scale insects, thrips, and red spider mites (eight-legged pests that cover a plant in a delicate, dense web) can appear. Check for damage and make sure the root system is sound. Cacti that have been kept in excessive moisture for an extended period of time may have rotted “from the pot,” which can also be brought on by fungi and bacteria. The real stem, which is green, may then feel supple.
Are all cacti prickly?
No. Cacti are typically thought of as desert plants, however there are also forest cacti that lack bristles; nonetheless, the variety that can be grown indoors is extremely limited.
How long does a cactus plant live?
Cacti can live for hundreds of years in the wild. They could live for ten years or longer indoors. The issue with old ones is that every single bump, scratch, or imperfection they receive stays with them; as a result, as they age, they start to look less attractive.
What makes a cactus a cactus?
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.”

A cactus can it move?
To emphasize the beauty, diversity, and extraordinary qualities of our common planet Earth, One Earth’s “Creature of the Week series” features a relatively obscure and unique species every Wednesday.
If you came across a creeping monster in the desert, you could have thought someone had used a machete to cut through a field of cacti. No, instead of seeming like a thorny snakes’ nest, this unique variety of cactus rests horizontally on the ground in colonies with only its tip pointed upward toward the sun. The crawling devil may also move across the desert on its belly, somewhat like snakes.
The creeping devil, also known by its scientific name Stenocereus eruca, is the only known moving cactus in the world and is an endemic to the state of Baja California Sur in northwest Mexico. The plant’s prostrate position aids in both its ability to move across the desert for extended periods of time as well as its ability to survive in solitude. It accomplishes this by spreading out horizontally from its stem while also eliminating its tail. It develops new roots as it gently creeps across the desert floor in order to attach itself and to take in water and nutrients. The plant receives nutrients back through the roots as a result of its back end disintegrating and assimilating with the soil. The creeping demon must, in a sense, kill off a portion of itself in order to travel, but this dead portion then feeds the newly formed living portion.
The climate where a creeping devil grows determines the pace of growth and the speed at which it moves. It moves at a speed of two feet each year in its natural region, where the climate is humid and marine.
This cactus can reproduce sexually, but due to its isolation and the dearth of pollinators in its natural habitat, it can also do so by cloning individual sections of itself, which separate from their bases, die, and then grow into new plants on their own.
Unfortunately, this enigmatic and unusual cactus is officially listed as an endangered plant in Mexico, mostly because of illegal trade. Cactus collectors will spend a lot of money to include it in their personal succulent gardens due to its uniqueness. On the illegal market, a single creeping devil stem can fetch between $4000 and $5000.
However, the agricultural sector poses a threat to this amazing cactus as well. To make room for their grazing cattle, for which the creeping devil is both an annoyance and a barrier to grazing, farmers will decimate entire colonies.
