Echinopsis eyriesii x Trichocereus candicans | ‘Eyricans’ | Live plant

(syn. Echinopsis eyriesii x Echinopsis candicans)

We’re pleased to offer healthy, well-rooted Echinopsis eyriesii x Trichocereus candicans hybrid cacti; cloned from a mother plant we originally bought from a German collector. We call such crosses ‘Eyricans’ – because why not?!

Echinopsis eyriesii x Trichocereus candicans is a really attractive example of an intergeneric hybrid, visibly reconfiguring the unusual mix of genetic traits inherited from its parent species. With a tendency to grow as prolific, clumping columns (from the main stem’s base and any cut or damaged areas, as with most cacti), these plants feature fairly sizeable, white and lightly-fluffy areoles – somewhat reminiscent of those of some crosses – and bears moderate spination, somewhere between those of its respective progenitors. The stems are a lush, medium-green (which is somewhere between the respective colouration of the parents), and are notably more Trichocereus-like than Echinopsis, typically being more rounded than those of the latter. 

This crossbreed’s mother plant, Echinopsis eyriesii, is a dark green, roughly cylindrical and globular to elongated cactus, reaching approximately thirty centimetres tall by fifteen centimetres or so in diameter. The species is generally caespitose in growth and occurs in parts of Argentina, Brazil and Uruguay, preferring lowland, continental or tropical habitats up to one-thousand metres above sea level. Echinopsis eyriesii is named for French researcher Alexandre Eyries and forms a complex with Echinopsis multiflora, Echinopsis multiplex and Echinopsis oxygona (and hybrids thereof).

The father of this excellent hybrid, Trichocereus candicans (synonymous with Echinopsis candicans and Trichocereus gladiatus) is a light yellow-to-green, columnar cactus species with a clumping tendency as it matures. Commonly called the ‘Argentine Giant’, it’s native to 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 many other Trichocereus species, 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 reach 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 are many of the Trichocereus species, candicans is a useful, good quality and hardy grafting root stock.

We cultivate this plant folling the same general practice as we do our other Trichocereus and Echinopsis species. Plant it in a well-drained, mildly-alkaline to mildly-acidic soil mix (equal parts soil and perlite works well), water only during the growing season (when the top few centimetres of soil become completely dry), and fertilise lightly a few times each year (also during the growth phase). Avoid frosts if you value your plants!
