Botanical Name: Echinofossulocactus crispatus
Common Name: Brain Cactus
Echinofossulocactus crispatus is a distinctive cactus native to central Mexico. It is known for its flattened, globular form and dramatically wavy ribs that give it a brain-like appearance. The pale green body is accented by fine spines, and mature plants produce delicate pink to purple flowers from the crown. This slow-growing species is popular with collectors and well-suited for container growing. Mature plants typically reach 6–8 inches tall and wide.
Care and Cultivation:
Prefers bright light to full sun
Water sparingly; allow soil to dry completely between waterings
Use a fast-draining cactus soil mix
Ideal for pots and collector displays
Frost Tolerance and Cold Hardiness:
Best suited for USDA Zones 9–11
Can tolerate brief cold down to about 20°F (-6°C) when dry
Protect from prolonged freezing and winter moisture
Winter Dormancy and Health:
Benefits from a cool, dry winter rest
Reduce watering significantly in winter
Dormancy encourages flowering
Notes:
Growth form varies slightly with age
Handle carefully; spines are fine but sharp
