The Brain Cactus, also known as the Mammillaria Elongata ‘Cristata’ cactus, is native to central Mexico. It’s a rare form of the Mammillaria Elongata cactus and has a unique, crested shape. Its growth pattern kind of looks like worms or brains, which is how it got the nickname Brain Cactus.
Mammillaria Elongata cacti are called Ladyfingers and grow nice and straight, but this crested form has stems with lots of kinks in them that grow in one big round clump. How did that happen?
It didn’t happen through cultivation—it actually happened through mutation or damage.
