Nestled slightly inland within a steep canyon system, this species relies entirely on the heavy Camanchaca fog that rolls off the Pacific ocean and forces its way up into the quebrada. The soft, dense canopy of white spines functions as a highly efficient moisture trap, catching the heavy airborne mist and channeling condensation down toward the root system. Its primary vegetative growth and metabolic processes occur during the cool, high-humidity months of late winter and spring. It enters a stagnant, defensive dormancy during the peak heat of summer. In cultivation, it demands a strictly mineral-dominant substrate (like an 80% pumice and crushed granite mix) to protect its highly sensitive roots from rot, and should be watered with a very disciplined hand only during the cool shoulder seasons.
