Isolatocereus dumortieri

Beautiful cactaceae made up of long columnar stems, which in nature reach even 15 m high! Of a nice pale green colour, tending to bluish, it has longitudinal ribs perfectly symmetrical and well grooved, along which are evenly distributed roundish and white areoles. The radial spines are arranged in radial patterns and the central spines are pointed outwards and slightly longer, all of an intense yellow that, reaching maturity, tends to become brown. It is very rare to find flowering Isolatocereus, as their blooming occurs only when the plant reaches its maximum size, however in nature it is possible to admire its beautiful flowers, rather large of a beautiful white, that match perfectly with the delicate stems.
