Cacti are fleshy and appear to be suitable as vegetables. It’s crucial to understand that there are edible and deadly cacti varieties before you start eating them.
All authentic cactus fruit is safe to consume. After the spines are removed, some varieties of cactus, including cholla, dragon fruit, and prickly pear, can be used as vegetables. Other cactus species, such as peyote, Bolivian, and San Pedro, are poisonous and should not be consumed.
Cacti of many types are frequently planted as indoor and outdoor ornamental plants. Check to see if the cactus variety is poisonous or suitable for people or pets to eat before choosing it for your garden.

Contrary to what the majority of people believe, almost all cactus fruits are edible and packed with beneficial minerals. The pads of the plants, for example, are also tasty. This wild fruit is sweet and healthful, just like any other fruit. But if you’ve never tried the fruit, you might be wondering whether it’s actually safe to eat. We’ve got you covered, so don’t worry.
Therefore, is cactus fruit toxic? No. Cactus fruits come in a variety of shapes and sizes, but none of them are poisonous. Eaten cactus fruits are all safe. The sole distinction between the fruits of various cacti species is that some are sourer and more bitter than others. All of them, though, are edible and safe to eat. The Opuntia genus produces a sizable portion of the edible cactus fruits.
Continue reading to learn more about cacti fruits and some of the most popular varieties. So let’s get started straight away.
What cactus has poison?
Due of its pointed spines, most people frequently choose to avoid cactus. Most cactus are not venomous, which may surprise you. Nevertheless, you might want to keep your kids and pets away from the following ones!
The most lethal cacti include the prickly pear, San Pedro cactus, Echinopsis Peruviana, Peyote, Barrel cactus, Saguaro cactus, Cholla cactus, and Euphorbia canariensis.
What determines if a cactus is edible?
Edible cacti and succulents are incredibly low-maintenance plants that taste great if your climate is right for them.
Some people want to know the distinction between succulents and cacti. A cactus is technically a succulent plant since the term refers to “one that has thick, fleshy, water-storing leaves or stems.” The term “cacti” is typically used to refer to succulent plants with spines, but all true cacti actually belong to the plant family Cactaceae.
Let’s discuss the numerous edible cacti and succulents that you can use in your landscaping:
Edible Cacti
All genuine cactus fruit is edible, but certain varieties have greater flavors than others. Some are excellent when cooked, and most must first have their spines peeled or otherwise removed before being consumed! Of course, everyone has varied tastes in stuff. In order to ensure that you enjoy them and are not allergic, it is advised to test a few of the cactus you are contemplating before purchasing.
Which edible cactus you select will depend on its intended purpose and the aesthetic of your edible landscaping. More than 200 Opuntia species, often known as Nopales, Nopalitos, the Cactus Pear, or the Paddle Cactus, contain a variety of delicious cacti.
The leaves and egg-shaped fruit (or “tunas”) of all Opuntias are edible. An Opuntia is recognized by its oval, flat, spine-covered leaves, or “paddles.”
Of all the edible cacti, Opuntia ficus-indica, also known as the prickly pear cactus, is the most well-known and popular. Its fruit and leaves, which are also known as the Indian Fig, are a mainstay in many recipes throughout Central America and the southwest of the United States. Australia, northern Africa, and the Galapagos Islands are just a few of the diverse areas this cactus has been introduced.
Opuntias are quite tolerant of the cold, and they can be found as far north as British Columbia. In some areas, they have also spread invasively. They can still be a stunning focal point in rock gardens or other drought-tolerant landscapes, and they have a wide range of uses in landscaping (they make great barrier hedges).
When fully grown, the saguaro (Carnegiea gigantea), the graceful representation of the desert in the southwest of the US, has edible fruit (which can take decades). The Saguaro, however, is hard to come by and cannot be moved without a permit.
Despite being smaller and with “arms” that often develop near the base of the plant rather than higher up the main stem, the Organ Pipe Cactus (Stenocereus thurberi) resembles the Saguaro. It has red Pitahaya Dulce fruit, which is roughly the size of a golf ball, and lavender flowers.
Visit the Organ Pipe Cactus National Monument in Arizona (United States), which is home to many of these beautiful cacti, to observe them in their natural habitat.
Fruit from barrel cacti can be harvested and eaten raw, and because it lacks spines, it is simple to handle. Additionally edible are the buds and blooms. One of the American Wild West myths was that you could cut open a barrel cactus and squeeze the pulp for water to keep you alive in the harsh desert.
The Night-Blooming Cereus (Hylocereus undatus), a cactus with long fleshy leaves and bright red or yellow fruit with a white or crimson core and black, crunchy seeds with great nutritional content, is also known as the Dragon Fruit or Pitaya (and is also known as Pitahaya Dulce in some locations). The plant only blooms at night and has enormous, fragrant white flowers.
Some species, such Peniocereus greggii, are also referred to as “Night-Blooming Cereus.”
Although it appears very different from Hylocereus, the Peruvian Apple Cactus (Cereus repandus), which likewise produces sweet, vividly colored edible fruit, is another cactus that bears the name Pitaya.
The Epiphyllum species, sometimes known as the orchid cactus, are another genus of cacti that are edible. They resemble the Hylocereus species in appearance and behavior but have smaller fruits. All of these have gorgeous flowers!
Edible Succulent Plants
In northern Africa and India, vegetables made from a few of the Caralluma species—Caralluma fimbriata, Caralluma adscendens, and Caralluma edulis—are consumed.
Many Agave species can be rendered edible, but the most famous is Agave tequilana, which is used to make tequila.
All Sedum species, also known as stonecrops, can be eaten. They taste sour or spicy and are used in salads. Consume these in moderation; excessive consumption of some may result in dyspepsia.
Purslane is beneficial as a ground cover in wet locations, is simple to grow, rather attractive, and delicious when cooked.
Although purslane is regarded as a weed in the US, it tastes delicious fried and is ok in salads and works well in stews and soups.
All prickly pear cacti are edible, right?
The lower 48 states of the United States are home to the eastern prickly pear cactus (Opuntia humifusa). In addition to being a lovely plant, it is edible, offers sustenance and safety to wildlife, and can be utilized in natural landscaping.
This cactus is simple to locate, especially in Indiana. The prickly pear features flat, fleshy pads (known as cladodes) covered in spiky spines, similar to other spiny succulents. Showy yellow blossoms are produced by the prickly pear.
How to eat a prickly pear
A red, egg-shaped fruit starts to form after flowering. After removing the skin, the fruits can be eaten raw and are edible. The fruit is frequently converted into jams, candies, and other sweets, and some people even eat the plant’s fleshy pads as a snack.
For thousands of years, the prickly pear cactus has been an essential part of Mexican and Central American cuisine. Prickly pears are becoming more popular as food in various areas of the United States.
The nopal, or cactus pad, which is frequently used as a vegetable, and the pear, or fruit, are the only two edible portions of the prickly pear plant.
What do prickly pears taste like?
Cactus pears have a sweet, rather bland flavor that is comparable to melon. The fruit is not technically a member of the pear family, despite its name. It was merely given that name because the prickly fruit looks and acts like a pear.
Where can I find prickly pears?
In Indiana, such as the Kankakee Sands and the Lake Michigan shore dunes, the prickly pear cactus can be found in open sand and arid places.
Another fantastic location to see Indiana’s sole cactus is the lovely Ober Savanna in Starke County.
Prickly pear in your yard
The fact that this native cactus is challenging to manage is unknown to many who like planting it in their backyards. A single plant can develop into a tangled, dense colony very fast.
The best approach to stop the prickly pear from spreading is to plant it in a pot. Purdue Pest & Plant Diagnostics Lab has a few options to get rid of prickly pear from your property if it is already out of control on the cactus.
When handling this lovely native cactus, be sure to use thick gloves. Their long, thorny spines, which can reach a length of several inches, are the least of your concerns. Glochids are painful and challenging to remove because of their hair-like appearance and decreased visibility.
Which nopales can you eat?
Nopal is a common name in Spanish for both the Opuntia cactus (often known in English as prickly pear) and its pads. Nopal is derived from the Nahuatl word nohpalli[nopali] for the plant’s pads.
There are 114 species that have been identified in Mexico,[1] where it is a prevalent element in many recipes that are part of the cuisine. The nopal pads can be consumed raw or cooked, added to soups, stews, salads, marmalades, traditional medicines, or used as animal feed. Although the pads of nearly all Opuntia species are edible, nopales grown for food are most frequently of the species Opuntia ficus-indica or Opuntia matudae. The fruit, also known as the “prickly pear” in English and the “tuna” in Spanish, is the other portion of the nopal cactus that can be eaten.
In Mexico, nopales are typically sold fresh, free of thorns, and cut to the customer’s specifications right away. They can also be obtained as nopalitos in cans or bottles, and less frequently dried, particularly for export. Nopales have a crisp, mucilaginous texture and a mild, slightly acidic flavor akin to green beans when cut into slices or diced into cubes. Most recipes call for cooking with the mucilaginous liquid they contain. In the spring, they are at their most supple and luscious. [2]
In Mexican food, nopales are most frequently used in meals like huevos with nopales (“eggs with nopales”), carne con nopales (“meat with nopales”), tacos de nopales (“nopal tacos”), salads with tomato, onion, and queso panela (“panela cheese”), or just by themselves as a side vegetable. Nopales have developed into a crucial component of Tejano culture in Texas as well as New Mexican cuisine[3].
A saguaro cactus can you eat it?
The distinctive saguaro cactus of the Sonoran Desert is unmistakable in appearance. These tall cactus only bear red fruit once a year, which normally ripens by late June. The fruit has a slight strawberry flavor and is packed with flesh and seeds. It can be consumed fresh or turned into syrup, jam, or wine. Saguaro fruit can only be harvested with a very long stick because they grow on the main stalk and crowns of the arms.
Can you eat purple cacti?
One of my favorites is the Santa-Rita prickly pear (Opuntia violaceae var. santa rita). Their blue-gray pads stand out so vividly in the environment against the various purple tones.
A stunning accent plant for the landscape, this cactus. Fruit and the pads are both edible (but you might want to remove the spines first ;-). Drought and cold temperatures make the purple color more intense.
The Santa-rita prickly pear is a native of the American Southwest. Although they have a maximum size of 6 feet by 6 feet, they can be pruned to keep a lesser size. Making pruning cuts at the intersection where the pads connect is how pruning is done skillfully.
In the spring, lovely yellow blooms appear, followed by red fruit in the summer. The pads can occasionally be eaten by javelina, rabbits, and pack rats. Pack rats construct their houses out of the pads.
The prickly pear’s pads are coated in glochids, which are small spines that cluster together in pairs. Glochids quickly separate from the pad and cause severe skin irritation. They feature a little sting at the tip, which makes it challenging to get them off your skin. Use a piece of carpet or a couple layers of newspaper to manage them if necessary. Avoid contacting the pads with gloves as this will cause the glochids to attach and render the gloves unusable (I ruined a perfectly good pair this way).
There are other techniques for getting rid of these tiny spines, including using Elmer’s glue (let it dry, then pick them off), but many people have found duct tape to be more effective.
USES: This type of prickly pear can be utilized as a screen as well as an accent plant in the landscape. Some people might be surprised to hear that they make wonderful container plants as well; just keep them away from locations with high foot activity. They thrive on well-drained soil and either direct sunlight or mild shade.
Prickly pears are extremely low-maintenance plants. To pick up the pruned pads, I always use tongs, although you could also use newspaper.
Despite their incredible drought tolerance, watering your prickly pears once a month during the hot summer months in the absence of rain will be appreciated and enhance their appearance. Shriveled pads are a sign of extreme drought stress.
The emergence of white, cotton-like patches on the pads is sometimes interpreted as an indication of a fungal infection. However, it is brought on by a tiny bug known as cochineal scale, which secretes the white cottony mass. The control is simple. That’s all there is to it—just give it a strong hose-jet wash!
Prickly pears can be grown from seeds, but there is a far simpler method. Simply remove a pad with a minimum height of 6 inches. Place the pad upright for at least two weeks in a dry, shaded area. As a result, a callus can develop at the bottom.
For the first month, do not water the plant; the bottom is prone to fungus infections. Plant with the cut end downward. Water the plant every 23 weeks after the first month until it gets established. Provide shade until the plant is established if planted in the summer (about three months). *In general, I advise against planting in the winter and in favor of waiting until the soil has warmed up in the spring.
If you have a sizable prickly pear, you can prune it or start anew by removing it, chopping off some of the pads, and planting them in the same spot. My clients have done this frequently and have been pleased with the outcomes.
Interesting historical fact: The cochineal scale insects release a dark red dye when crushed, which is why the Aztecs would grow prickly pear cactus afflicted with them. Clothes were dyed using this. This dye was brought back to Europe by the Spanish from Mexico, where it was used to color royal clothing and British military outfits. The Spanish regarded the dye highly, second only to gold and silver. One pound of dye requires 70,000 insects to be produced.
*There are several lovely prickly pear species that can be grown in a backyard garden. What is your favorite variety of prickly pear cactus?
