This is a fast-growing cactus that should be kept in a pot, otherwise it can get to be 13′ tall and 10′ wide. They prefer their nighttime temperatures to not go below 40F, although it can survive a slight frost. Some reports indicate that it is semi-deciduous in that the “leaves” may drop during its winter dormant period. It should be kept fairly dry in winter. That also means it wants a very free draining soil so as to not rot. Regular water during summer.
The crested form is said to be a cultivation artifact and potentially caused by damage when the plant is small. It produces large fans that are tipped with the succulent leaves. They also do have a few sharp spines.
