Although it originated in the Andes, the San Pedro cactus (Trichocereus pachanoi) is now widespread throughout the southwest of the United States. Although the San Pedro cactus is typically grown for decorative purposes, it is also farmed for the component mescaline, a restricted chemical that can have psychedelic effects if taken, similar to the peyote cactus. While it is lawful to cultivate a San Pedro cactus anywhere in the globe, including the US, it is prohibited to remove the mescaline and use, trade, or sell it. One of the cacti with the highest rate of growth, the San Pedro cactus can be distinguished from other cacti by a few distinctive characteristics.
Observe its expansion. Up to 20 feet tall and 6 feet broad, a San Pedro cactus can grow up to a foot every year.
Examine its shape. A San Pedro cactus is a tubular, vertically growing, typically armless cactus. The same crown can produce more than one stem.

Count the vertical columns or ribs that run the length of the cactus. A San Pedro cactus contains 6 to 8 circular columns or ribs in total, each with a tiny spike on top to deter predators.
Check out its blossoms, which open out at night when it is cooler. White blooms appear on San Pedro cacti typically around July. They have a nine-inch maximum diameter.
Compare the cactus in question to a photo of a San Pedro cactus. Alternately, you might bring a photo of the cactus to your neighbourhood nursery or county extension office so they can determine whether it is a San Pedro cactus or not.

A hallucinogenic San Pedro cactus?
Since many cacti contain phenethylaminealkaloids like mescaline, they are known to be psychedelic.
[1] The most hallucinogenic species of the Echinopsis genus, which includes the San Pedro cactus (Echinopsis pachanoi, also known as Trichocereus pachanoi), and the Lophophora genus, which includes peyote (Lophophora williamsii), are the two primary ritualistic (folkloric) genera. Other species from various genera are likewise psychoactive, however they are not necessarily utilised for ritualistic purposes. [2] [3] [4]
About Trichocereus pachanoi
San Pedro cactus is the popular name for Trichocereus pachanoi (syn. Echinopsis pachanoi, Cereus pachanoi). This lovely columnar cactus is indigenous to the mountains of Ecuador, Bolivia, Peru, and northern Argentina, where it can be found growing between 1200 and 2600 metres above sea level. Trichocereus pachanoi is a particularly resilient cactus that can resist harsh conditions, including freezing temperatures, in the Andes mountains (-11C).
Regarding the variety of spines on San Pedro Cactus, we frequently receive inquiries. Be not frightened. The spines of Trichocereus pachanoi vary greatly. Some plants’ stems are completely devoid of spines, while others have 3–8 yellow–brown spines. These spines might measure 1-3 centimetres in length. Additionally, a San Pedro cactus without spines may develop them later in life.
Trichocereus pachanoi (Echinopsis pachanoi) is a columnar cactus with 4–8 ribs and occasionally several stems that grows quickly—up to half its length in a year. In nature, it can grow to a height of 5 to 6 metres. San Pedro flowers have a lovely white colour and bloom at night. They also have a pleasant scent.
Cultivation of Trichocereus pachanoi
As was already said, San Pedro cactus is a very resilient plant that grows quickly and easily. The optimum soil for growing this cactus is one that is loose, well-draining, fertile, and allows for a steady release of nutrients. With a soil mixture of 50% ordinary potting soil, 25% grit or Perlite, and 25% worm manure, I get good results (compost). During the growing season, Trichocereus pachanoi requires routine irrigation as well as sporadic (roughly every two months) applications of additional liquid fertiliser. Older plants can withstand full sun (even outside the greenhouse), but younger plants should be handled carefully. When the light intensity is abruptly increased, they may turn red (stress). Keep these cacti cool and nearly dry in the winter, but try to keep them as well lit as you can to avoid etiolation (thin, yellow growth).
Trichocereus pachanoi from seed and cuttings
San Pedro cactus seeds are simple to germinate. By carefully following the seed-raising instructions, you can do this.
Cuttings of the San Pedro Cactus can also be rooted, for example in our specially formulated cactus rooting mix. Cactus rooting powder can help the rooting process go more quickly and effectively. Let the cut wound heal for a few weeks before adding the cutting to the rooting mix. Cuttings of the potted San Pedro Cactus will begin to root in about two to six weeks.
Is it permitted to market San Pedro cacti?
According to Australia’s Poisons Standard, mescaline is a category 9 poison (February 2020). While the peyote cactus and other mescaline-containing plants like San Pedro are forbidden in Western Australia, Queensland, and the Northern Territory, they are permitted for ornamental and gardening use in Tasmania, Victoria, and New South Wales[1].
Due to the prohibitions specified on Portaria SVS/MS no344, possession, manufacture, and sale are prohibited.
[2]
Peyote is permitted but mescaline and any salt of mescaline is prohibited (lophophora).
[3] Other plants, such the San Pedro cactus, are not exempt and may only be grown for decorative purposes. [4]
“Cacti and seeds from Echinopsis pachanoi, Echinopsis peruviana, and other species that contain the drug mescaline are prohibited. (3,4,5-trimethoxy-phenethylamin).” [5]
The decree defining the list of drugs categorised as narcotics on February 22, 1990 includes mescaline as one of those substances[6].
Lophophora williamsi has been “relegated” on February 22, 1990 after first being listed in table B of drugs in 1966 and then table A of dangerous substances in 1957.
No restrictions apply to cacti. The Anlage I BtMG governs mescaline. Without a licence, it is forbidden to produce, possess, import, export, buy, sell, procure, or administer it. [7]
The cultivation, production, manufacture, possession, sale, purchase, transportation, storage, consumption, or distribution of mescaline are all prohibited under the NDPS Act in India.
It is prohibited to buy, transport, or sell mescaline because it is included under Table 1 of Italy’s “Tabelle delle sostanze stupefacenti e psicotrope.” Except for Peyote, psychotropic cacti can be bought legally from florists, garden centres, and online stores. [8]
Both mescaline and peyote are prohibited according to the Ley General de Salud. It does not mention the Peruvian Torch or the San Pedro cactus, thus they are completely lawful.
How can I recognise a cactus?
The physical characteristics of each cactus should be used as a starting point when distinguishing one from another. Some distinguishing physical characteristics to watch for are:
The Leaves
One essential aspect you may want to consider is the cactus plant’s leaves. Do your plants have any spines? You can determine this by examining their leaves. A leaf with spines will have needle-like, sharp edges, while a leaf without spines will have rounded edges. The colour and shape of your cacti plant’s leaves can also provide useful information.
Chlorophyll and carotenoids, which are photosynthetic pigments, can be used to determine the colour of leaves. Carotenoids give the plants their characteristic colours, whereas chlorophyll is in charge of receiving light energy from the sun and storing it as chemical energy.
Your cactus plant type may also be determined by the shape of the leaves. Succulent plants often have spines and needle-like leaves, whereas flat-leaved plants are typically stronger in nature since they can endure severe situations better. For instance, the leaves of a barrel cactus grow straight, whereas the leaves of a saguaro cactus are flat.
Similar to the shape and colour, the different needle styles can also be used to identify the type of cacti you have, albeit the results are not always reliable. The more hardy and leafy kinds will typically have flat spines, whilst the more succulent and squishy forms would typically have needle-like spines.
How high can they grow?
When determining the type of cactus you have, you might also want to consider its height. Because plants that thrive at higher elevations typically have longer roots than those that do not, height and altitude can be utilised as a determining factor when choosing your plant type. The Saguaro Cactus, which may often reach heights of 50 feet, is the tallest of all succulents. Hedgehog and pereskia, on the other hand, are little kinds that rarely grow taller than six inches. You can tell what kind of cactus plant you have by just measuring the height of the plant.
Shape and coloration
When there are no spines or leaves to go by, a cactus’ shape and colour can also be utilised to determine its type. Shape typically gives some hints about the plant’s requirements for the climate, which in turn may give more information about the nature of the plant.
Although there are so many different kinds of cactus that you can identify, you might not be able to do so just by looking at it because of its colour. Another spiny variety may have a green-brown body, whereas a white-spined barrel cactus may have green. The dwarf saguaro’s yellowish hue stands out sharply from, for example, the brown spines on a barbed wire cactus.
As you can see, there are a lot of physical characteristics to watch out for that could reveal what species of cactus plant your plants are. One piece of advice is to explore further if you notice something peculiar or unusual about a particular species because it might be what you’ve been looking for.
How are its flowering style and pattern?
The way a plant blooms is another physical characteristic that will reveal whether it is a terrestrial or epiphytic plant. While terrestrial plants have roots and require direct connection to soil, epiphytes are plants that thrive in humid regions with little soil contact and depend on other plants for nutrition.
Another sign of a cactus’ kind is the way its flowers are arranged. The saguaro and barrel both feature radial patterns, while the hedgehog is another plant with radial patterns but more elongated ones. A species that forms columns, like the cardon, may have vertical stripes or zigzags with contrasting colour patterns.
The most likely form of cactus you have is a cardon if it is columnar and has vertical stripes of contrasting colours. On the other hand, if your cactus has radial patterns and spines, it is probably either the barrel or saguaro type.
Although it’s not always reliable, the colour of the flowers might also give you a hint about what kind of cactus your plant is. For instance, a hedgehog may have yellow blooms, or a kind of flower with a red top may be a cardon.
What about the seeds?
Depending on their environment, different cactus species generate different seeds. For instance, the Saguaro cactus produces smaller, fleshier seed pods, whereas the hedgehog produces much larger, spiky fruit. While the cardon is known to produce seeds that are round and glossy, some varieties, like the barrel cactus, will have a more oval or spherical appearance.
These various seed pod varieties can provide you hints about the kind of cactus you might grow in your garden. Perhaps after a lengthy development period, your plant that you’ve had for a while isn’t blossoming or generating any flowers? Even before planting, it may be quite beneficial to look at the seeds, since they might provide important details about the type of plant. If your cactus isn’t flowering or generating any flowers over a lengthy time of growth, it may not be blossoming due to its type or the climatic circumstances that type loves. Different cactus species generate different seed pods.
