(Trichocereus scopulicola x Trichocereus bridgesii ‘Psycho0’) x Trichocereus bridgesii ‘Short Spine’ | 25 seeds

A great addition to our selection, (Trichocereus scopulicola x Trichocereus bridgesii ‘Psycho0′) x Trichocereus bridgesii ‘Short Spine’ comes all the way from Australia and combines the genetics of two of our favourite cactus species! Great quality seed and another EU exclusive!

The mother of this cool hybrid is a crossbreed itself, Trichocereus scopulicola x Trichocereus bridgesii Psycho0′. Trichocereus scopulicola (syn. Echinopsis scopulicola, Trichocereus scopulicolus) is encountered only rarely in the wild, sometimes growing in Bolivia’s Department Tarija, at an elevation of roughly one to one and a half thousand metres. Unlike many other Trichocereus species, it has very short spines – which means handling larger specimens is much less painful! Growing to three or four metres tall and a maximum of around ten centimetres diameter once mature, this night-flowering species is presumed to be a particularly close relative to Trichocereus bridgesii, with which it readily forms hybrids (obviously!).

The extremely popular ‘Psycho0’ clone is commonly considered to be a gorgeous strain of the fast-growing Trichocereus bridgesii (syn: Echinopsis lageniformis, ‘Bolivian Torch’) – although it has been suggested it may have been crossed with something else somewhere along the way. The ‘Psycho0’ usually produces bridgesii-type plants with strong, long yellow spines and often forms three that are unusually strong and unique in appearance. It can also produce both short-spined and more traditional bridgesii-type cacti. Originating from the Australian Trichocereus community, it was initially distributed among a few SAB forum members and was named in memory of a community member who passed away.

The father strain is the ‘Short Spine’ form of Trichocereus bridgesii, which is a fast-growing columnar cactus from Bolivia. Taller than scopulicola, bridgesii can grow up to roughly six metres high, branching at the base and forming stems of roughly fifteen to twenty centimetres cm in diameter. Under suitable conditions, mature plants will grow up to thirty centimetres or so a year! Closely-related to Trichocereus pachanoi (‘San Pedro’) and Trichocereus peruvianus (‘Peruvian Torch’), bridgesii is a beautiful cactus, recognisable by its four to ten centimetre long spines. It’s been used by Bolivian shaman, as a universal grafting stock (offering a high success rate and a long-life span of steady fast growth) and as a hedge or defensive plant.

Growing naturally at high altitude, bridgesii withstands temperatures below -12°C and can be grown indoors in the UK. The species is prized by cactus collectors both for its gorgeous appearance and for its very large (up to twenty centimetres in diameter) fragrant flowers, which are absolutely wonderful and bloom on summer nights.

As with most Trichocereus cactus species, these hybrid 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.

    Back to report these had 100% germination at one week after planting in takeaway – still vigorously growing – so very pleased!

      😀 That’s pretty amazing, well done you! We must admit to having a bit of a soft-spot for this hybrid; you can’t really go wrong with any of the parents, after all.


    I want a near- naked bridgesii, and I think I can get one with this combo 😉

      Do send a photo or two once you have some results, we’ve only just sown our first batch of these ourselves…
