Trichocereus pachanoi (syn. Echinopsis pachanoi – commonly known as ‘San Pedro’) is a fast-growing columnar cactus found naturally in Argentina, Bolivia, Chile, Ecuador and Peru. A native of the Ecuadorian and Peruvian Andes Mountains, where it prefers an altitude range of around 6,600 to 9,800 feet, pachanoi has been used for by humans for more than three thousand years, variously as an ornamental, for religious divination, in traditional medicine (human and animal) and as a solid and universal grafting stock.
Pachanoi is a light to dark green cactus, growing up to twenty feet tall (although the highest recorded was forty feet!) 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.
Hailing from Peru, Trichocereus huanucoensis (or huancoensis) is a less well-known – but highly prized – species. Rarely available in Europe, there’s currently very little information available on this magnificent variety, but here’s what we do know… Apparently native to Huánuco, Peru, huanucoensis is a rapidly growing, wide-ribbed and thick-stemmed branching columnar species, reaching up to seven metres high and with stems of approximately twenty centimetres in diameter. Blue-green in colour and highly variable in appearance (dependent on habitat), plants of this type may have either long, golden spines or (commonly) none at all and produce beautiful white nocturnal blooms.
A fairly obscure and rarely marketed cactus that’s nevertheless much admired by the hardcore Trichocereus fanatic, huanucoensis is not actually considered to be a ‘true’ species as of writing. Rather, the plants known by that name are generally believed to fall somewhere on the pachanoi–peruvianus spectrum, displaying characteristics similar to other plants within this complex. Some authorities have also conjectured a relationship with or intermediate form of Trichocereus santaensis, due to similarities in flower morphology. Notably, the Trichocereus huanucoensis found cultivated outside its natural habitat in Peru is suspected by many to originate from material imported into the USA in the 1950s by nursery owner Harry Johnson senior.
Whether huanucoensis is ever “definitely” identified, it’s a great addition to any discerning collection, combining many of the best traits of the closely-related Trichocereus pachanoi (‘San Pedro’) and Trichocereus peruvianus (‘Peruvian Torch’). As with those species, huanucoensis should handle anything from USDA Zones 8-10, where it may average roughly thirty centimetres of new growth per year in ideal conditions. Make sure to provide fertile, free-draining soil and regular watering and watch this fatty get even fatter!
These amazing Trichocereus pachanoi x Trichocereus huanucoensis hybrid seeds are very easy to germinate and grow and their main requirements consist of high humidity levels, a free-draining soil mix and enough water, light and nutrients. They can easily be grown indoors in the UK and Europe.
