Trichocereus rowleyi (ex. grandiflorus) [form 1] | ‘Red Torch’ | Live plant

(syn. Chamaecereus grandiflorus, Echinopsis calochlora, Echinopsis grandiflora, Echinopsis huascha v. grandiflora, Helianthocereus grandiflora, Helianthocereus grandiflorus, Helianthocereus huascha, Lobivia grandiflora, Lobivia grandiflorus, Lobivia huascha v. grandiflora, Soehrensia grandiflora, Trichocereus grandiflora, Trichocereus grandiflorus, Trichocereus huascha v. grandiflora, Trichocereus huascha v. grandiflorus)

This one’s another classic – yet much-debated! – Trichocereus species: Trichocereus rowleyi (ex. grandiflorus) [form 1] (we named it solely as we sell other forms here). Available as healthy, rooted seed-grown plants.

Often still called by an older species epithet, Trichocereus grandiflorus (and various permutations thereof), Trichocereus rowleyi is a somewhat controversial and rather variable species which has been reclassified between genera several times. This is clear from its many aliases – this species is currently (or was previously) synonymous with Echinopsis calochlora, Echinopsis grandiflora, Echinopsis huascha, Helianthocereus grandiflora, Helianthocereus grandiflorus, Helianthocereus huascha, Lobivia grandiflora, Lobivia grandiflorus, Soehrensia grandiflora, Trichocereus grandiflora, Trichocereus grandiflorus, Trichocereus huascha, Trichocereus huascha var. grandiflora and Trichocereus huascha var. grandiflorus.

Grandiflorus was apparently first brought to the commercial market by Alberto Vojtechii Fric (who ended up with two Lophophora species named after him), under the name of Chamaecereus giganteus. A hardy and multiple-ribbed (between twelve and eighteen) columnar Argentine species native to the region of Catamarca, it was originally discovered growing in a private collection, rather in the wild. It’s informally known as the ‘Desert’s Blooming Jewel’ or ‘Red Torch’ cactus, and is considered as extremely close to – perhaps even a type of – Trichocereus huascha (albeit with noticeably shorter spination compared to the latter cacti). It’s also rather similar in appearance to its close relative, Trichocereus schickendantzii, but differs in such aspects as flower colour and branching habit.

Occurring naturally on the very arid grassy and rocky slopes of the Puna de Atacama, at between roughly one-thousand and two-thousand-one-hundred-metres above sea level, Trichocereus rowleyi grows to a maximum height of roughly ninety-centimetres / three-feet. Its green columns grow to a mature diameter of up to ten centimetres / four inches or so, with more sprouting from the plant’s base (starting as small, globular pups) profusely as time goes on. Spination is generally up to one-centimetre / half-an-inch (approximately), needle-like and coloured brown-red-tan-yellow. This species is known for its incredibly impressive flowers (unsurprising, given the English meaning of grand-i-flora) – even more so than most of the other species of the genus, which is really saying something! Funnel-shaped and up to roughly twenty-five centimetres / ten inches in diameter, these night-blooming flowers are most often red, although are commonly also orange, yellow (or various similar hues; occasionally white). Matters are complicated due to the extreme popularity of this species as a parent for a multitude of Trichocereus and intergeneric hybrids, resulting in all sorts of forms – and confusion both in meat-space and online! There’s also a dark-red-flowered dwarf form, Trichocereus rowleyi f. herzogii, which grows from “Tucuman to Jujuy to Salta to Catamarca” and is likely a naturally-occurring crossbreed.

We cultivate these plants in a well-drained, mildly acidic to mildly alkaline soil mix (roughly equal parts soil and perlite – or similar). Water only during the growing season, whenever the top layer of soil dries out to the touch (put your finger in, a centimetre or two deep, to test). Lightly fertilise a few times each season and avoid frost and you can expect to enjoy your Trichocereus rowleyi for many years to come!
