Copiapoa humilis CRESTED is a fascinating cactus cultivar known for its unusual growth habit. Unlike the typical globular form of Copiapoa humilis, the crested form develops into a contorted, brain-like shape. This intriguing appearance is caused by a mutation that leads to abnormal cell growth at the growing tip. Native to Chile, this slow-growing cactus thrives in arid environments and produces stunning yellow flowers.
