Cacti plants are a particularly hardy category of plants, and they are diversified in addition to being hardy. You might be surprised at what other conditions some cacti can grow in considering how well-known they are for their ability to survive with minimal water and in harsh desert surroundings.
Which cactus grows best in low light conditions indoors? The answer is that there are several different types of cacti, including the scarlet ball cactus, crown cactus, zebra cactus, and Christmas cactus, that can thrive and flourish in low, filtered, or indirect light.
While the cacti that flourish in blindingly brilliant, intensely hot desert situations are the ones that everyone is most familiar with, there are other species that do extremely well in other locations. If you want to brighten up your apartment, office, or any other dimly lit room, you could be pleasantly surprised by the variety of cacti options available to you.
The four best cacti to grow indoors and in areas with little to no light will be covered in this article.
Cacti may exist without sunlight.
If you are unfamiliar with cacti plants, you might be unsure of their ability to live in the absence of sunlight. These are desert plants, after all, and you would be inclined to believe that shielding them from the sun is beneficial for them. Is that indeed the case? Most likely not.
Can a cactus survive in the absence of sunlight? The quick response is “no” Like other plants, cacti require sunlight to survive. Although these arid plants can endure brief periods of darkness, they require a lot of sunlight to grow and bloom. A mini-cacti plant typically needs four hours or more of direct sunlight each day to thrive.
Some cacti species are marketed as low light plants because they lack spines. The Christmas cactus is a nice illustration of this kind of cactus. The issue is that if you don’t give your cacti plants enough sunlight, they’ll become malnourished and maybe die.
What transpires if a cactus doesn’t receive sufficient light?
The technical term for when a plant begins “stretching” or becoming “leggy” is “etiolation.” Any plant can experience it, but because succulents and cacti are frequently so little, it stands out more in their case.
It’s easy to figure out why etiolation takes place – the plant isn’t getting enough light! Towards response, they start to grow swiftly (and spindly) in the direction of the light they perceive. They produce fewer leaves while they are experiencing etiolated growth. They occasionally just don’t grow at all!
It’s crucial to understand that etiolated growth doesn’t necessarily indicate a plant is ill. It needed more light, for sure, but it’s not in any danger of perishing, I think.
The only real drawback of etiolation is the unpleasant appearance it gives your succulent. It is also regrettably irreversible. A plant that has etiolated is permanently in that state.
You’re left with no choice except to remove the etiolated portion. The succulent or cactus will frequently start growing again after the cut has healed. It can lead to some rather intriguing outcomes! The cut-off portion will typically sprout if you plant it in some dirt.
Which cactus don’t require sun?
A group of 19 cacti in the genus Epiphyllum can thrive in less sunny environments. These cacti are also known as climbing cacti and orchid cacti. The epiphyllum cactus is relatively hardy and doesn’t require much maintenance.
Tropical epiphytic cacti called epiphyllum have thin branches and are typically serrated. The most well-known Epiphyllum species include Epiphyllum oxypetalum, strictum, pumila, and others.
Beautiful, fragrant, big flowers, some up to a foot long, are also produced by epiphyllum. Although their coloring can vary, it is often yellow, orange, and pink. From late spring through mid-summer, different flowers blossom.
Due to their tropical and epiphytic nature, epiphyllum receive less sunlight in their native environment because they are typically hidden by branches and other objects.
If your home doesn’t receive much sunlight during the day, you should be able to place your Epiphyllum cactus on the brightest windowsill you have. For these cacti, even a little period of morning sun is frequently sufficient. Bright yet filtered light is ideal for the remainder of the day.
You may need to be cautious when watering because there will likely be less sun and a lower temperature. Winter’s lowest temperature is 60 F. (16 Celsius). To prevent rot, wait until the soil is completely dry before watering. With a stick or a soil meter like this, you can measure the moisture in the soil.
#2: Eriocereus, or Harrisia cacti
A group of about 20 cacti in the genus Harrisia quickly and attractively bloom. These cacti have flowers that are about 6-7 inches (15-18 cm) long and bloom nocturnally (at night). These cactus feature the typical cacti appearance, including spines on the stem.
Harrisiajusbertii is one of the most well-known members of this genus of cactus. Among other well-known species are pomanensis, bonplandii, and others.
Although Harrisia cacti can withstand light shade and lack of sunlight, they can also withstand partial shade and even some full sun. Place on a windowsill that gets at least some morning to afternoon sun if staying indoors. Protect the cactus from the cold in the winter and make sure the summertime temperature is at least 55 F. (13 Celsius).
#3: Hatiora cacti
A tiny genus of epiphytic cactus called Hatiora has largely spineless leaves. These cacti have numerous branching stems that drop down and are attractive both inside and outside.
If you keep your Hatiora indoors and don’t get much sunlight, put it on a windowsill or another location where it will get as much light as possible. Brilliant morning light and indirect yet bright light throughout the remainder of the day provide the greatest illumination. During the winter, let them hibernate.
To prevent burns, these cacti need cover outside rather than direct sunlight. Be cautious while watering these cacti, and only do so when the soil has largely dried up. The ideal summertime temperature for these cacti is between 70 and 72 degrees Fahrenheit (21-22 C).
You can discover epiphylloides, cylindrica, herminiae, and other hybrids in the Hatiora genus of cacti.
#4: Lepismium cacti
A genus of tropical cactus called Lepismium can survive without direct sunlight and doesn’t need it. In their natural environments, these cacti live on trees or rocks. They bloom in addition to having numerous branching branches (often referred to as trailing plants).
These cactus will look fantastic in offices and interior settings. They just require a few hours of direct light in the morning, so maintain them in a sunny area with warm temperatures.
These cactus will benefit considerably from morning sun in the direct and afternoon shade in the complete. They hate being soggy, so use caution when watering them. Bolivianum, cruciforme, and other Lepismium cactus species are common.
#5: Gymnocalicium cacti
Gymnocalicium, often known as chin cacti, are spine-equipped little and adorable cacti. Gymnocalicium require more direct sunlight than the other cacti listed in this article, yet in their natural habitat, they typically flourish in partial shade.
If you typically have plenty of bright light, at least for a few hours in the morning and shaded light for the remainder of the day, you can grow them at home.
Unless you can maintain them on a bright windowsill, these cacti are not the ideal choice for office desktops. To get plenty of bright light indoors, set them on a bright windowsill. Make sure they are shielded from the sun’s rays throughout the midday hours.
Most Gymnocalicium cacti require protection from direct sunlight. You might need to avoid picking some species because they require full sun. Some species, like schickendantzii and mostii, need full sun.
#6: Schlumbergera cacti
Schlumbergera, popularly known as holiday cacti, is a little genus with few cacti in it. Other common names for these well-known and stunning cacti include Christmas cactus and Mistletoe cactus.
Schlumbergera don’t have the typical cactus appearance; instead, they feature numerous split stem and leaf segments that are fused together. They also have lovely flowers that grow from the areoles and stem tips, most of which are pink but can also be white or yellow. Due to the latter season of their flowering, these cacti received their name.
Schlumbergera are highly common in Northern Hemisphere nations with less sunlight because they thrive in low light and higher humidity conditions (about 60%). Keep this cactus away from drafts, cold, and full sun in the summer and winter.
#7: Rhipsalis cacti
There are about 43 tropical cacti in the genus Rhipsalis, and several of them have hanging stems. In the wild, they can grow on both rocks and trees. You may cultivate these lovely cacti in areas that are both bright and shaded.
These cacti prefer mild summers; temperatures above 77 F (25 C) may be harmful. Put your Rhipsalis cactus in a sunny area with a few hours of morning to afternoon direct sunlight if possible. Shade the cactus thereafter to avoid burns and scarring. Allow them to dorm in the winter and maintain a temperature of about 59 F. (15 C).

Can cacti endure artificial lighting?
When the melocactus reaches maturity, it transforms into a huge, ribbed ball with a cap on top.
You probably already know that cactus plants require light to survive. Depending on the type, plants might differ greatly from one another.
Look at the plant to learn where it came from and what kind of light it prefers.
Spiny succulents require intense light to develop properly, although they can tolerate less. If kept in pots by a window, they could get sunburned.
Shield them from the sun’s intense beams. Without spines, succulents thrive in bright to filtered light with some shade from the intense sun.
Light and Day Length
Cacti and other succulents thrive under 16 hours of a mixture of fluorescent and incandescent light that is 10 watts fluorescent to 1 watt incandescent.
You must learn a little about the specific needs of your plants if you desire blossoms. Before they will bloom, some need to be kept chilly for a while, and others need a good nap with lots of darkness.
Schlumbergera bridgesii, the Christmas cactus, for instance, needs to be maintained relatively dry, with temperatures kept below 60 degrees Fahrenheit and eight-hour days (and sixteen-hour nights) to promote blooming. Set a timer or cover the plant with a dark, opaque cloth every night.
Typically, we use the terms “bright,” “filtered,” and “shady” to describe different forms of light. These definitions mean as follows:
Bright. When there are no drapes or blinds between the plant and the window, it signifies bright light or full sun. There are no obstructions to the outside light on the other side of the window, such as a tree, sign, or structure. A distinct, sharp shadow is produced when your hand is held one foot over a piece of paper under intense light.
Filtered. This refers to sunlight that is filtered via a glass window curtain. Your hand casts a hazy, but distinct shadow when placed a foot above a piece of type paper under filtered light.
Shady. This means that there should be no direct sunlight or other sources of light, and holding your hand a foot over a piece of paper will only result in a blob. All shade-tolerant plants require high humidity levels.
Cacti are well recognized for surviving in the hot, dry desert, but they also require water to grow. Find out what cactus plants need in terms of humidity and water in the next section.
Can cacti thrive in shade?
Can cacti thrive in the shade? While some cacti may survive in low light, most cacti require light to survive. A cactus should actually be kept indoors where it can receive at least 4 hours of light every day. Cacti require direct sunlight or very bright indirect light. The ideal indoor sites for cacti are typically on windowsills that face south or east.
Cacti need a lot of light because they are desert plants. However, each variety of cactus has different lighting requirements. It could be helpful to do some study on the particular type of cactus you have. We’ll make an effort to explain how much light your cactus needs in this article.
Cacti can they live inside?
Despite being recognized for their love of sunlight, many cacti grow well as houseplants. For some unusual decor, place one on your windowsill or in your living area. The ideal houseplant, indoor cacti typically require less light and are smaller in stature.
Bunny Ears Cactus (Opuntia microdasys)
The bunny ears cactus gets its name from its look and is native to Mexico. Its two pads are designed like bunny ears. They should be handled carefully since they have glochids or brown prickles on them. The bunny ears cactus is the ideal indoor plant because it may reach heights of two to three feet. If given enough light, it will blossom with white flowers and bear purple fruits in the summer.
Chin Cactus (Gymnocalycium)
Gymnocalycium is a kind of cactus native to South America and is frequently referred to as the “chin cactus.” Greek for “naked kalyx,” its name alludes to the flower buds’ lack of hair or spines. Some chin cactus like shade, while others do better in sunlight, depending on the kind.
Saguaro Cactus (Carnegiea gigantea)
Although it grows slowly, the Saguaro cactus can reach a height of forty feet. This indicates that you can use it as an indoor plant for a number of years before relocating it outside. It has the traditional cactus appearance thanks to its barrel-shaped body. This plant, which is a native of the Sonoran Desert, needs a lot of sunshine. Place the plant in direct sunlight if it is being maintained indoors.
Old Lady Cactus (Mammillaria hahniana)
The mammillaria family, which comprises 250 species, includes the old lady cactus as a subspecies of pincushion cactus. It is renowned for its halo of small pink or purple flowers that bloom in the spring and possesses hairs and spines. A sandy potting mix should be used to plant the old lady cactus, and it should receive water every other week.
Star Cactus (Astrophytum asteria)
The star cactus, also known as sea urchin or sand dollar cactus, can be recognized by its circular body that is divided into eight slices. It has small white spots and white hairs all over it. It produces a yellow blossom in the spring. The star cactus is the perfect indoor plant because its diameter only reaches two to six inches.
Easter Cactus (Hatiora gaertneri)
Easter cactus, a native of Brazil, blooms in late winter or early spring. White, orange, and lavender are just a few of its bloom colors. The plant has a distinctive shape because of the way its spines are piled on top of one another.
Christmas Cactus (Schlumbergera bridgesii)
The Christmas cactus, which is frequently mistaken for the Thanksgiving cactus, blooms in the dead of winter. It boasts vivid red blossoms and is frequently given as a Christmas gift. The Christmas cactus thrives in average indoor settings. Don’t overwater plants because it will make their roots rot. Although this plant can thrive in low light conditions, its blossoms benefit from additional light.
Moon Cactus (Gymnocalycium mihanovichii)
The moon cactus, also referred to as the chin cactus, varies in size, shape, and color. The hibotan cactus is a well-known cultivar. Its South American origins can be traced to its vivid red, pink, yellow, and orange hues. On window sills that receive some light, these little plants flourish.
