led the "brain cactus," the succulent is native to central Mexico, according to Succulent City. It's a rare form of the Mammillaria Elongata cactus, which typically grows straight. But thanks to mutation or damage to its center of growth, the brain cactus' crested form has stems that grow in a big clump. Doesn't a mutated plant just scream Halloween?
As with most succulents, the brain cactus is easy to take care of. Keep it in bright, direct sunlight and water it sparingly. Just be sure not to over water it because if an excess amount of water gets into the folds, it'll rot. The folks at Succulent City recommend using a small watering can and pointing the spout at the soil so you don't get water on the body of the brain cactus. They also suggest repotting the cactus with succulent soil, or soil that drains well once you get it. If you do transfer the brain cactus to a new planter (we recommend a skull-shaped one), be careful because its spines can do some damage.
