Its name literally means "Cereus that grows isolated", in reference to its unusual custom of not forming groups of stems, like the other Cereus, but of growing in solitary. It is an extremely rare cactaceae, probably little diffused also for its dimensions, which can exceed in nature the 15 metres of height! To this genre belongs only another species, Isolatocereus dumortieri, so much showy and particular to deserve a new genus on its own. Only when the plant is mature, will it be able to develop its wonderful white flowers. The charm of these huge thorny columns, so solemn and majestic, on its own, will certainly not go unnoticed! Here are some tips for its cultivation: Isolatocereus prefers to be exposed to full sun and putted in rather aired conditions. It is preferable to keep it at mild temperatures that are supposed to never go below 10 º C, for this reason it is recommended to place it in sheltered and in airy places during the winter. Water it moderately, only when the soil is completely dry. It’s enough once a week in the spring and summer, a reduction on a bimonthly basis in the fall and completely suspended in the winter. It is optimal a well draining and mineral-rich substrate, for example a suitable soil for cactus, to which you can add pumice. They do not need frequent fertilizations, it will be sufficient to dilute a specific cacti and succulents fertilizer with the water of the waterings once a year.
