This is one of the largest cactus, nearly globular, broadly columnar, or barrel shaped, often very massive stems. It could live more than a hundred years and is easily recognized because of its massive size, by far the largest of all barrel cacti. They are day-flowering plants with vivid yellow flowers produced in spring and summer-autumn. Plants that flower in the spring and autumn, produce fruits in summer and winter respectively.
