Answer:
Cacti are among my favorite plant species, and their needles undoubtedly make them distinctive. In many respects, the needles that cover cactus are essential to their survival. Since many cacti are found in dry environments, these plants need to store a lot of water in order to thrive. In fact, according to scientists, water makes up between 90 and 94 percent of a cactus plant. Cacti are ideal treats for thirsty species due to their high water content. Animals that consume cactus in the wild include quail, kangaroo rats, sheep, desert tortoises, as well as a variety of insects. In order to stop thirsty or hungry animals from eating or harming the plant, cacti contain needles.
Additionally, you could see that the color and texture of cactus spines might vary. While some spines are fluffy, others are stiff. The color of the spines can also vary, from white to gray to pink! Because of these variations in spine color and texture, cactus can more effectively blend into their surroundings (i.e. camouflage). Therefore, a second reason cacti have needles is to enable them to conceal from harmful species.
Heat is a significant issue in desert regions where there are many cacti. The needles of a cactus can offer protection from the sun so that it can thrive in these scorching temperatures. Although it may not seem like a single needle may offer much shade, several cacti species have needles that are grouped closely together. The plant is shaded by these spine clusters, which resemble small umbrellas. These spines provide shade for the cactus, which helps keep water from evaporating and causing water loss.
All in all, cactus use their spines as protective and hiding mechanisms against potential predators. Additionally, they give the plant shade, which keeps it cooler and prevents water loss.
Are there thorns or spines on cacti?
A cactus’ spines are significantly altered leaves. Since cactus plants are located in desert areas, their numerous spines serve a variety of purposes. The plants’ leaves have been changed to become spines. Consequently, the cactus plant has a great deal of thorns or spines.
Do cacti really have that many thorns?
The cactus family is known for its prickly spines, which are actually altered leaves. The kind of leaves that a maple or oak tree has are not present on cacti. But in the distant past, they might have had leaves that were at least somewhat more similar. Due to the fact that they aid the plants in surviving in hot, dry situations, those leaves eventually changed into the prickly spines we see on cactuses today.
“They could serve as a defensive strategy to prevent herbivores, or animals that consume plants, from consuming the cactus. But spines also produce shade! “Kimberlie McCue says.
“When you are covered with spines, those spines are throwing shadows on the cactus’ body as the sun moves across the sky. They are tiny umbrellas for shade.”
All cacti are native to arid regions, and some can even survive in dry climates. How do they acquire water to exist, then? Kimberlie informs us that these plants can be found close to the water.
“There will be fog coming off the ocean in the morning. Water condenses on those spines, forming tiny droplets, which then flow down the spine, to the plant’s body, to the soil, and to the roots.”
As they hold the soil in place and offer shelter to birds and other creatures, cactuses are also crucial components of their desert ecosystems. In exchange, such animals and birds assist in pollinating the cactus flowers. Cacti are a significant local source of food for people.
Cactuses are unfortunately threatened by people who illegally steal natural plants from their surroundings. According to Kimberlie McCue, being cautious when purchasing cactus plants is one method to ensure that cacti remain healthy and numerous. Before you buy, find out where the cactus came from and confirm that the vendor is being a responsible steward of these plants.
What is the name for cactus spines?
a species of Opuntia with glochids and spines. The glochids are the tiny prickles at the center of the bunches, whereas the spines are the relatively big, radiating organs.
Glochids, also known as glochidia (plural “glochidium”), are small, usually barbed spines or prickles that are present on the areoles of cacti belonging to the Opuntioideae subfamily. Glochids from cacti quickly separate from the plant and ensnare in the skin, irritating it when they come into touch. Some cactus species have tufts of glochids in the areoles that nearly completely cover the stem surfaces, with each tuft containing hundreds of glochids. These tufts may exist in addition to or in place of the larger, more noticeable cactus spines, which are typically not barbed and are difficult to detach.
Exist any cacti that lack spines?
The strange-looking but endearing Lophophora williamsii is a globe-shaped, spineless cactus. It frequently has a dip in the center. They have strong roots, good growth, and require little maintenance. Peyote resemble dumplings, and they are frequently referred to as “dumpling cactus.”
The plant is spherical and tiny, and its ribs are tuberous. The middle of this cactus is where their tiny, pink blossoms appear.
These cactus enjoy warmth and strong illumination. However, protect this cactus from intense direct sunlight. Take peyote indoors throughout the winter if the temperature falls below 50 F (10 C). They require a period of dormancy in the winter, so water sparingly only once every 5 to 6 weeks, and keep plants in a dry, cool environment.
When growing in groups, Lophophora williamsii frequently has beautiful appearance (they form clumps). Allowing this cactus to develop with offsets makes them more aesthetically pleasing because they are relatively tiny in size. They require ventilation as well as well-draining soil.
If you have kids or animals that can consume peyote, you shouldn’t keep it. That’s because it contains mescaline, which when ingested has psychedelic effects.
#2: Astrophytum myriostigma
Bishop’s cap, commonly known as Astrophytum myriostigma, is a cactus without any spines. Myriostigma, which means “dotted,” is a plant whose stem is covered in numerous tiny white dots.
Although it might be more challenging to maintain and has weak roots, this cactus can also grow on its own. Choose a light, quick-draining soil instead, and only water it when the soil is completely dry.
Only until it reaches a height of about 3 inches (8 cm) does it begin to bloom. Their yellow blossoms have a pleasant aroma. In the astrophytum genus, there is a species called Myriostigma coahuilense that is extremely similar to it.
This cactus requires winter dormancy and prefers bright but primarily shaded light. They are fairly resilient and can withstand colder weather, up to below freezing, before you need to bring them inside.
#3: Astrophytum asterias
Another species of cactus in this genus, Astrophytum asterias, lacks spines. This cactus is little, adorable, and spherical in form. Grayish-green in hue. These cacti are stunning additions to any collection of cacti due to the white dots in the midst of the areoles.

#18: Rhipsaliscacti
A genus of tropical cactus known as mistletoe cacti is called Rhipsalis. The majority of Rhipsalis cacti lack spines and don’t have the traditional appearance of a cactus. Rhipsalis cacti are found in about 43 different species.
The stems of almost all Rhipsalis species are thin and drooping. They bloom all day long, and their blossoms are white.
Rhipsalis are epiphytic cacti, meaning they grow on other plants and trees. This means they require bright, but partly shaded light. Any temperature over 77 F (25 C), especially outside, could be harmful to them. They are able to handle direct, strong light, but not when it is the warmest of the day.
Likewise, use caution when watering.
only water the soil when it is dry. They dislike extremely moist soil. Most people love warm weather, so if you plan to leave them outside beyond 50 degrees Fahrenheit, bring them inside (10 C). They gain from fertilization in the summer.
