Trichocereus scopulicola

Trichocereus scopulicola is a columnar cactus characterized by its robust, dark green to glaucous green stems. It typically features 4 to 6 broad, rounded ribs with flat, inconspicuous areoles. Spines are extremely short, often absent or reduced to tiny, blunt radials, making the plant appear virtually spineless. Flowers are large, nocturnal, white, and fragrant, typical of the genus.

The primary documented origin of Trichocereus scopulicola in cultivation is the collection by German botanist Friedrich Ritter in Bolivia under the field number FR991. The species is widely believed to be highly restricted in its native habitat, with some community members suggesting it may be functionally extinct in the wild due to grazing by introduced goats. However, rumors and unconfirmed reports of wild populations and alternative seed collections persist.

While specific cultivation notes were not detailed in the community discussion, Trichocereus scopulicola generally thrives in a well-draining mineral soil mix. It prefers moderate to heavy watering during the active growing season (spring through autumn) and should be kept dry during winter dormancy. It tolerates partial shade to full sun, though protection from intense afternoon sun is recommended in hot climates.
