This unique cactus is renowned for its pleasantly chaotic appearance. Mammillaria elongata 'Cristata', AKA "Brain Cactus," is true to its name. This cactus showcases uncommon, curvy stems resembling either worms or brains. The brain cactus forms a dense cluster of twisted green stems, each adorned with wooly areoles bearing yellow or copper spines. Each specimen comes in a unique shape, often displaying a blend of mutated and normal growth. To showcase this beauty, place your brain cactus in a fun, quirky pot to make a statement.
