Eulychnia is a genus of candelabriform or arborescent cacti, comprising of about 9 species. These desert cacti can survive under very hot conditions where temperatures can reach up to 50 degrees Celsius. Furthermore, this breed of cacti can also survive in some of the driest places in the world such as the Atacama Desert, the driest desert in the world.

This species presents no problems in cultivation and will do well in a sunny spot in a cactus house. These plants will tolerate sun and heat, but not extended periods of frost. Grow them in rich, porous, sandy soil, and let their soil dry out between watering. If potted, repot in the spring, if their roots become cramped. Generally, they should be repotted every other year in order to provide fresh soil. However, this doesn’t necessarily mean they’ll need larger containers. Fill about a quarter of the pot with broken crocks, gravel, etc. to promote good drainage. After repotting, do not water for a week or more. The crested plants enjoy a warm sunny environment and for more speedy growth a light position on a higher shelf with light feeding and rainwater given to the bottom of the plant will ensure success, especially with rooted detached branches, which do well in these conditions.
