Trichocereus pachanoi x Trichocereus macrogonus | Seeds

Arkham’s Botanical is happy to announce yet another of our UK exclusives (possibly the EU too in this case?) – great quality 2019 harvest Trichocereus pachanoi x Trichocereus macrogonus hybrid seeds from America. Jump on these quick, they’re sure to form some gorgeous plants!

Trichocereus pachanoi (syn. Echinopsis pachanoi – commonly known as ‘San Pedro’), 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 and in traditional medicine (human and animal).

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.

Trichocereus macrogonus (syn. Echinopsis macrogona) is another fast-growing columnar Trichocereus cactus from Bolivia, which is not only closely related to the popular species Trichocereus bridgesii and Trichocereus pachanoi, but is particularly entwined with the ‘Peruvian Torch’, Trichocereus peruvianus (both macrogonus and peruvianus are currently ‘contending’ names, which many people consider to be synonymous).

A lovely blue-green in colour, macrogonus grows to around three metres high once mature. Its stems, growing up to approximately ten centimetres in diameter, are studded with brown to yellow brown spines up to five centimetres long. A self-sterile species, macrogonus blooms only at night, forming white flowers which can reach roughly eighteen centimetres across.

As with those of many of its relations, macrogonus seeds need exposure to light and a minimum temperature of 25°C to 30°C before they will germinate. Happy to grow indoors or outside within USDA Hardiness Zones 8-10, this hardy plant will easily average roughly thirty centimetres growth per year, presuming an ideal climate. Macrogonus is easily propagated from seed or cuttings – requiring fertile, free-draining soil and regular water – and is one of our favourite Trichocereus species!

These two Trichocereus species are regarded as useful universal grafting stocks, offering a high success rate and a long-lifetime of speedy and consistent growth. These 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. This Trichocereus pachanoi x Trichocereus macrogonus hybrid seed can be easily grown indoors in the UK and Europe, so what are you waiting for?!

All the seed sold by Arkham’s Botanical was freshly and ethically sourced
