The cause of cresting:
The cause of cresting is not fully explained
Biologists disagree as to why some plants grow in this unusual form.  Some speculate that it is a genetic mutation. Others say it is the result of a strike of lightning  or freeze damage, but whatever the stimulus, the growth point of the stem has switched from a geometric point, to a line, which folds and undulates as the crest expands. Though these crested E. subdenudata are very rare, cresting occurs naturally, and can be encountered in many other cactus species.

Cultivation: The grafted plants are easy to grow and will form a large brain-like mounds  with age.  Watering during the active growing season (spring and summer); this will encourage steady growth, and prevent the large tubercles from becoming flabby.
The plants on their own roots do well under cultivation. Use very draining soil, water during the aestival growth cycle (They need plenty of water), but need to be avoided  wetting the bodies of these plants while they are in sunlight. A wet cactus in the sun light can cause sun burning which can lead to scares or even fungal infections and death.
Need half sun. Keep dry at 10°C in winter, but they can tolerate sporadic light frost.
Propagation:
Grafting or stem cutting.
