Trichocereus pallarensis x Trichocereus pachanoi ‘OST90641’ | 25 seeds

We’re incredibly excited to be able to offer this rather rare Trichocereus pallarensis x Trichocereus pachanoi ‘OST90641’ seed – another of our UK exclusives, all the way from the USA!

Trichocereus pallarensis (syn. Echinopsis pallarensis) is a very rare, often disputed species, which appears to occur on the same continuum as Trichocereus pachanoi, Trichocereus peruvianus (‘Peruvian Torch’) and Trichocereus santaensis. Apparently native to only two or three regions of northern Peru (at an altitude of between two and a half thousand to three thousand metres above sea level), pallarensis was first described as a species by Fredrick Ritter around 1961 (although he also described it as a pachanoi variety!). As far as we’re aware, at least two collections of this cactus have been recorded: ‘FR676’ and ‘FR1468’.

Very similar to pachanoi in appearance, pallarensis is a slightly stout, columnar green cactus which possesses thin, brown-honey-tan spines, up to roughly fifty millimetres in length. The flowers are white and are followed by fruit up to approximately five centimetres long, three or four centimetres in diameter and covered in grey hairs.

‘OST90641’ is a Trichocereus pachanoi (syn. Echinopsis pachanoi – commonly called “San Pedro”) clone – the species being a fast-growing columnar cactus found naturally in Argentina, Bolivia, Chile, Ecuador and Peru. Originating from the Ecuadorian and Peruvian Andes Mountains, where it prefers to grow at an altitude of roughly two to three thousand metres, pachanoi has been used for by humans for more than three thousand years, variously as an ornamental, for religious divination and in traditional medicine (human and animal).

Light to dark green in colour, pachanoi grows up to about six metres high (although the highest recorded was twelve metres!) under ideal conditions in USDA Zones 8-10. Its stems, usually forming multiple branches from the plants base, grow up to fifteen centimetres in diameter and generally possess six to eight ribs. Its origins in the Andes enable it to withstand far lower temperatures than can many other cacti and it’s consequently easy to grow indoors and outdoors in most areas.

As with most Trichocereus cactus species, these seeds are very easy to germinate and grow in USDA Hardiness Zones 8-11! Their main requirements consist of high humidity levels, free-draining (mildly acidic to mildly alkaline) soil and sufficient light, water and nutrients. Space plants roughly three metres apart to allow them enough room to reach maturity. Easily grown indoors in the UK and Europe!
