# Brain Cactus (Stenocactus multicostatus)

> Native to the highland deserts of Mexico, Stenocactus multicostatus is celebrated for its extraordinary morphology featuring over 100 thin, wavy, accordion-like ribs that resemble brain convolutions. In early spring, it produces striking pale pink to white flowers with a distinctive purple central midstripe at the apex. Its compact, spherical habit and undulating geometry make it an essential centerpiece in specialized cactus collections.
