Trichocereus candicans ‘JO804.1′ | ‘Argentine Giant’ | Live plant

(syn. Echinopsis candicans, Trichocereus gladiatus)

Here’s some chunky Trichocereus candicans ‘JO804.1’, a locality collection about which we know nothing other than its collection number! Available as well-rooted, seed-grown plants from the Freaky Cacti shop.

Before we outline the species in general, we should mention that we believe that these genetics were originally obtained by Czech collector Josef Odehnal (based on both the country we first bought such plants from and the records of the much-appreciated Cactus and Succulent Field Number website). If you know anything else about this form, please do let us know by email, so we can expand this listing.

Known popularly as the ‘Argentine Giant’, candicans (syn. Echinopsis candicans, Trichocereus gladiatus) is a light yellow-to-green, columnar cactus species with a clumping tendency as it matures. It’s a native of the desert regions of northern and western Argentina. This is an extremely variable species in both form and habit, with clumped patches being recorded as growing up to roughly three-metres in diameter – individual stems getting as tall as (approximately) seventyfive centimetres. Such stems usually comprise of nine to eleven ribs, and measure up to about fifteen centimetres in diameter. Spination tends to be brown through to yellow and ranges from four to ten centimetres in length.

In common with, candicans produces wonderful, scented blooms, usually – but not always – white to whitish in colour (they can be red or yellow too, apparently). These night-blooming flowers approximately twenty centimetres in diameter, and are also self-sterile (meaning that they require pollination from a separate genetic line to form fruits and seeds). Candicans is believed to be particularly intimately-related to (and sometimes naturally interbreeds with) Trichocereus huascha (syn. Trichocereus grandiflorus), Trichocereus lamprochlorus, Trichocereus neolamprochlorus, Trichocereus pseudocandicans and Trichocereus strigosus. Further, there are many recognised varieties (notably Trichocereus candicans var. gladiatus, Trichocereus candicans var. robustior, Trichocereus candicans var. rubriflorus and Trichocereus candicans var. tenuispinus) and popular cultivars and nursery-produced hybrids. As do many of the other Trichocereus species, candicans is a useful, good quality and hardy grafting root stock.

Grow this species in a free-draining, mildly acidic to mildly alkaline soil mix – we suggest roughly equal measures soil and perlite (or similar) – and provide full but not searing sunshine for maximum growth. Water only as the top few centimetres of substrate dries out completely, fertilising up to three times a year (or to personal preference). Candicans is considered comparatively drought and frost tolerant, preferring a minimum of around 10°C).
