We came to the spectacular Trichocereus terscheckii (syn. Echinopsis terscheckii) relatively late in our initiation into the world of Trichocereus cultivation, when we came across one in a friend’s garden, causing us to appreciate how magnificent this cactus really is! A large columnar species originating from Argentina, Bolivia, Ecuador and Peru, the plant’s most often called ‘Argentine Saguaro’ and ‘Cardón Grande’ (less often so ‘Cardón Santos’, ‘Golden Saguaro’, ‘San Pedro’ and ‘South American Saguaro’). Growing well in USDA Hardiness Zones 8-11 (as do many, for example, the closely related Trichocereus pachanoi and Trichocereus peruvianus), it’s easy and fun to grow, branching into columns which reach up to approximately ten metres in height and fifty centimetres in diameter. Terscheckii also forms amazing flowers, given the right cultivation conditions.

Trichocereus thelegonus (synonymous with Cereus thelegona, Cereus thelegonus, Echinopsis thelegona, Echinopsis thelegonus, Soehrensia thelegona and Trichocereus thelegona) is a branching, columnar species native to the north-west of Argentina, growing in the provinces of Jujuy, Salta and Tucumán at between approximately five-and-a-half-thousand to one-thousand-one-hundred metres above sea level. Reaching a maximum diameter of approximately ten centimetres and a mature height of just over two metres, this distinctive species bears yellow-brown-reddish spines up to two-and-a-half centimetres long. It blooms at night, producing long, white (self-sterile) flowers and round, reddish fruit (wih a diameter of roughly five or six centimetres). Unfortunately, we don’t have any further details on the specific thelegonus hybrid used in the breeding of this Trichocereus terscheckii x (Trichocereus thelegonus hybrid) crossbreed, but – based on its offspring – it must have been a looker!

Care-wise, we treat this Trichocereus terscheckii x (Trichocereus thelegonus hybrid) much the same as our Trichocereus pachanoi, Trichocereus spachianus, etc. Basically, plant in a well-drained, mildly acidic to mildly alkaline soil, watering only when the top few centimetres of soil is completely dry to the touch. We also lightly fertilise our plants one, two or three times over the warmer months, tailing off watering over the colder, damper winter months in an effort to avoid encouraging rot or other unwanted issues.
