Stenocactus multicostatus

Stenocactus multicostatus, widely known as the Brain Cactus or Wave Cactus, is a visually striking succulent native to the high-altitude arid regions of central Mexico, including Coahuila, Chihuahua, and Durango. It is characterized by its numerous, thin, and undulating ribs—sometimes numbering over 100 on a single specimen—which give it a unique, wrinkled appearance reminiscent of a brain. The plant showcased in the image features vibrant, funnel-shaped flowers with distinctive pink mid-stripes on white or pale petals, a classic trait of the species in bloom.

While its natural origin is the rocky limestone soils of Mexico, this cactus is commercially cultivated worldwide by specialist nurseries and succulent growers to meet the demand of the ornamental plant market. Because it is a botanical species rather than a manufactured consumer product, its 'manufacturing' refers to commercial greenhouse cultivation, which occurs globally, particularly in regions with suitable climates like the United States (California, Arizona), Southern Europe, and Southeast Asia. The tag visible in the image is a common identification marker used by nurseries to indicate scientific name and price (8.50), typical of specialized plant shops or botanical collections.
