The cristate form (Mammillaria bocasana f. cristata), often called “Brain Cactus,” produces dense, twisting crests that form tight, sculptural clumps over time. Plants can reach 15–20 cm across in 5–10 years under good culture. This plant will be sent bare-rooted (without soil) for safe shipping.
Care
Light: Bright light to full sun to keep growth compact and spines dense.
Water: Water thoroughly in warmer months, allowing soil to dry between waterings; water sparingly in winter.
Temperature: Prefers warm, dry conditions; protect from frost.
Media: Free-draining cactus mix to prevent rot.
Fertiliser: Apply low-nitrogen cactus fertiliser during active growth for best form.
