Trichocereus peruvianus ‘Clyde’ x Trichocereus huanucoensis | 25 seeds
Here’s another of our UK exclusives – the absolutely incredible Trichocereus hybrid, Trichocereus peruvianus ‘Clyde’ x Trichocereus huanucoensis! Rarely available in Europe, this is a great way to add some sought-after genetics to your garden with a cool cactus crossbreed…
‘Clyde’ is a recently-popularised strain of the fabulous Trichocereus peruvianus (syn. Echinopsis peruviana, ‘Peruvian Torch’) – an impressive, fast-growing columnar cactus, closely related to Trichocereus bridgesii (‘Achuma’, ‘Bolivian Torch’) and Trichocereus pachanoi (‘San Pedro’). Peruvianus is covered with fierce, reddish-brown-white spines (between approximately two and eight centimetres long) and forms frosted, blue-green coloured columns (up to approximately eighteen centimetres in diameter) that reach up to six metres tall. Gorgeous, white to whitish flowers bloom between late spring and summer.
Native to the Peruvian Andes (growing at a height of around two thousand to three thousand metres), peruvianus forms a complex intergrade with related species including Trichocereus cuzcoensis and Trichocereus macrogonus, which loosely comprises of many fantastic varieties and hybrids. As are many of the columnar Trichocereus species, the species is often used as a hedge plant and also as an important adjunct to certain indigenous medicine practices.
Apparently native to Huánuco, Peru, Trichocereus huanucoensis is another 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 most columnar Trichocereus species, this hybrid will thrive in anywhere from USDA Hardiness Zone 8 to USDA Hardiness Zone 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!
