San Pedro: Trichocereus (Echinopsis) Species

Desert Plants

San Pedro cactus, also known as Trichocereus pachanoi (formerly known as echinopsis pachanoi), is a plant native to the Andes Mountains of South America. Its psychoactive properties have been used for centuries by indigenous people for medicinal and spiritual purposes in San Pedro ceremony. It is therefore a sacred cactus, with a long history.

The San Pedro cactus plant is a dark green, columnar cactus that can grow up to 20 feet tall in its natural habitat. Its stems can reach up to 8 inches in diameter, and it has large, white, fragrant flowers that bloom at night. The plant contains mescaline, a psychoactive alkaloid that produces hallucinations and other altered states of consciousness (it is illegal in the UK to extract or prepare the mescaline from the plant).

San Pedro cacti are relatively easy to grow and care for. They require well-draining soil, regular watering, and lots of sunlight. San Pedro cactus plants can be propagated through cuttings, which can be taken from the top or side of the stem. These cuttings can be rooted in soil and will eventually grow into new plants.

When buying San Pedro cactus, it is important to choose a reputable seller. Look for sellers who offer healthy, well-established plants and cuttings. Be wary of sellers who offer San Pedro cacti at unusually low prices, as these may be lower quality or even fake.

San Pedro cactus is a fascinating plant with a rich history and many uses historically. It can be propagated through cloning (cutting), seed grown or grafted. Just be sure to choose a reputable seller and take proper care of your new plant to ensure its health and longevity.

The psychoactive compound found in San Pedro cactus, is a controlled substance in the United Kingdom. It is classified as a Class A drug under the Misuse of Drugs Act 1971, which makes it illegal to possess, produce, sell, or import mescaline without a license.

While the cactus itself is legal to own and grow in the UK, it is illegal to extract or prepare the mescaline from the plant.

The Trichocereus genus is a group of cacti native to South America, particularly the Andes region. There are many different species and hybrids within the genus, including several popular ornamental plants. Here are some of the most common Trichocereus varieties:

  1. Trichocereus pachanoi (Formerly Echinopsis pachanoi): Also known as San Pedro cactus, this is one of the most well-known and widely cultivated Trichocereus species. San Pedro cacti are one of the fastest growing columnar cacti, native to the Andes Mountains of Ecuador and Peru. Given the optimum environment, this cactus can grow up to 30cm per year! Night blooming, the mature San Pedro displays signature, giant white flowers from July and produces a fragrant bouquet whilst in bloom.

  2. Trichocereus bridgesii (formerly Echinopsis lageniformis): Also known as Bolivian Torch cactus, this species is known for its long, thin stems that can grow up to several meters tall and are covered in spines. The cactus also produces white, nocturnal flowers that bloom in the summer.

There is some debate among taxonomists and cactus enthusiasts regarding the exact number of Trichocereus species, as well as which species belong in the genus. Currently, there are believed to be around 50 recognized Trichocereus species, although this number is subject to change as new research and taxonomic studies are conducted.
