Echinofossulocactus crispatus, also known as the Brain Cactus or Stenocactus crispatus, is a fascinating species native to arid regions of central Mexico. It is cherished for its compact, globular form and its numerous thin, undulating ribs that create a distinctive, rippled texture — almost like the folds of a brain.

Typically reaching up to 10–15 cm in diameter, this cactus produces a stunning floral display in spring, with delicate funnel-shaped flowers in shades of lavender to deep violet, often with darker mid-stripes. The contrast between the finely pleated body and the vivid blooms makes this species particularly attractive for collectors.

Ideal for container culture, Echinofossulocactus crispatus thrives in full sun and well-draining, mineral-rich soil. It is drought-tolerant and relatively easy to care for, making it suitable for beginners and seasoned growers alike. Protect from frost and avoid overwatering to maintain healthy growth and encourage blooming.

A true gem among cacti, this species adds sculptural beauty and color to any succulent collection or rock garden.
