Trichocereus macrogonus ‘Fields’ x Trichocereus scopulicola | 25 seeds

This is a great opportunity to get your hands on some rather cool Trichocereus macrogonus ‘Fields’ x Trichocereus scopulicola cactus seed! This one’s all the way from Australia, so expect good things once it’s sown out; it’s also another of our UK exclusives!

Trichocereus macrogonus (syn. Echinopsis macrogona) is a fast-growing columnar Trichocereus cactus from Bolivia, which is not only closely related to the popular species Trichocereus bridgesii (‘Bolivian Torch’) and Trichocereus pachanoi (‘San Pedro’), 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. The macrogonus variety contributing to this crossbreed originates from the world famous ‘Fields’ collection and is a great example of the species!

Another Bolivian cactus – although this time found rarely in nature – Trichocereus scopulicola (syn. Echinopsis scopulicola, Trichocereus scopulicolus) grows in Bolivia’s Department Tarija, at roughly one to one and a half thousand metres elevation.

Reaching three or four metres tall and roughly ten centimetres in diameter, this night-flowering cactus is presumed to be a particularly close relative to Trichocereus bridgesii, with which it readily forms hybrids. Unlike many other Trichocereus species, the scopulicola has unusually short spines, which means it’s that much more pleasant when handling them is required!

As with those of most Trichocereus, these 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. Easily propagated from seed or cuttings – requiring fertile, free-draining soil and regular water.
