Cereus azureus is a cactus native of Brasil, Central America and some areas of the South America.
Cereus azureus is an erected, columnar cactus. The stem is green or greyish, and in the adult plant the cephalium gets bristly.
Cereus azureus needs to be fertilized at least once a year; it requires well drained sol mix and regular waterings during the growth period, that have to decrease during the winter. If the soil is dry enough, the plant can survive temperatures close to zero. It normally requires full sun exposition.
Propagation can be done by cutting.
During the summer it produces nocturnal flowers of different colours.
