Description: It is a slowly growing massive barrel cactus usually solitary that grows huge in habitat (up to 2.5 m tall, 1.5 m wide). It could live more than a hundred years. This cactus is easily recognized by it's large size, being the largest of all barrel cacti.
Flowers: Diurnal, vivid yellow.
Blooming season: From end of spring to summer only on larger mature specimens receiving enough full sun.
Cultivation and propagation: Frost tender but resistant to -4°C for short periods. Cold hardiness increases with improved drainage, so keep plants as dry as possible in winter. They grow best in well-drained soil and a position in full sun, which will help to maintain the luster of the spines and longevity of the flowers. Provide the plant with extremely well-drained soils, as the plant are subject to crown and soft rot if it remains too moist.
