Encephalocarpus, formerly known as Pelecyphora strobiliformis, has had a chequered taxonomical history and is native to the Mexican desert. The name of this genus is derived from the Greek en (in), kephale (head) and karpos (fruit), because first the flowers and then the fruit appear at the apex of the stem. The specific name, on the other hand, refers to the shape of its tubercles, which are reminiscent of the scales on the strobilus – or cone – of a conifer. These plants have a diameter of a few centimetres, turnip-shaped roots, and many more spines on the tubercles when young, which disappear as the tubercles mature. Considered as difficult to grow, these are actually very rustic plants. Provide a granular and calcareous mineral soil, good sun exposure and ventilation, and be patient as they are very slow growing. They bloom several times in the summer.
