Mammillaria hahniana f. cristata

The cristate form (Mammillaria hahniana f. cristata) develops brain-like crests instead of the normal globular shape. Plants form tight, fan-shaped clusters covered in dense white spines with pinkish wool, creating a striking sculptural look. This plant will be sent bare-rooted (without soil) for safe shipping.

Care

• Light: Full sun to bright light for dense spine development.
• Water: Water thoroughly when dry in summer; keep almost dry in winter.
• Temperature: Tolerates cool to warm conditions (5–30 °C); protect from frost.
• Media: Well-drained cactus mix.
• Fertiliser: Apply diluted cactus fertiliser during growing season.
