Origin and Habitat
Mountains of Peru, Ecuador, Bolivia, and northern Argentina. It is sub-spontaneous in several South American and in some tropical countries in other continents.
Altitude: It grows between 2000 and 3300 meters above sea level.
Habitat
Trichocereus (Echinopsis) pachanoi has a wide distribution and stable population. It grows naturally in the high-altitude dry shrublands and high-rainfall areas of the Andes. It can withstand temperatures far below that of many other cacti.
UK Growing
In the UK, San Pedro Cactus are quite popular due to their hardiness and can handle our low temp during winter (around 5C before bringing them inside, although, adults can go lower). Flowers produce after around 10 years of growth, so, patience is required.
All our cacti are shipped bare root to protect the cacti, please ensure you have suitable substrate and a pot for your new dude.
Synonyms
- Echinopsis pachanoi
- San Pedro Cactus
- Wachuma
Some Additional Info
Trichocereus (except for bridgesii / Bolivian Torch) are very hardy and weather tolerant. Trichocereus pachanoi can handle temps as low as -9c for very short periods.
Native to South America, the earliest evidence of San Pedro was found in Peru, specifically, the Guitarrero cave of the Callejón de Huaylas valley. They are natively found in the Andes Mountains at altitude levels around 2000m – 3000m. San Pedro (the class of Trichocereus) is also found in regions like Argentina, Bolivia, Colombia, Chile, Ecuador, Peru, and Venezuela.
Trichocereus pachanoi are night bloomers with these gorgeous flowers doing their thing at night, you have to be quick or you will miss the event :-). A flower event is a special event as it can take anywhere from 5 years to 8 years for an adult plant to produce a flower. When they do, you do your happy dance, thank the cactus Gods, snap a million pics, harvest the pollen, and wait for the next event.

San Pedro cactus seedlings for UK growers
These San Pedro cactus seedlings are seed-grown Trichocereus pachanoi, also listed under the older botanical name Echinopsis pachanoi. They are a good choice if you want an established young plant rather than starting from seed, while still keeping the character and variation that comes from seed-grown stock.
Seedlings, seeds or cuts?
- Seedlings: best if you want a young rooted plant that is already past the earliest germination stage.
- Seeds: best if you want to raise a batch from the start and do not mind a slower project. See San Pedro cactus seeds.
- Cuts: best when available if you want a larger piece of plant material to root on. See San Pedro cactus cuts or the Tr. pachanoi category.
What to expect from this listing
- Botanical names: Trichocereus pachanoi / Echinopsis pachanoi.
- Common name: San Pedro cactus.
- Current format: rooted seedlings, with size options shown in the selector above when available.
- Dispatch: sent bare root to reduce transit damage and keep the plant safer in the post.
- Before arrival: have a free-draining cactus substrate and suitable pot ready.
UK growing notes
San Pedro is one of the more forgiving Trichocereus for UK growers, especially compared with slower globular cacti. Give seedlings bright light, airflow and a mineral-leaning free-draining mix. Avoid keeping young plants cold and wet, particularly outside the active growing season.

Byron is a very helpful person, he sends an automatic email with written care instructions PLUS he answered one of my emails in about twenty minutes; he gave me great advice and answered my question. He's a very helpful person! I think he deserves all the credit as he seems to be honest in his business and cares about his customers.
