Mammillaria elongata f. cristata 'Brain Cactus'

Brain Cactus (Mammillaria elongata ‘Cristata’) is a quirky and captivating succulent named for its unusual, brain-like growth pattern. Unlike the typical upright form of Mammillaria, this crested variety twists and curves into convoluted folds, creating a sculptural, almost abstract shape that instantly draws attention. Its surface is dotted with small, golden spines that offer a soft, fuzzy look—making it a favorite among collectors and curious plant lovers alike.

This cactus adds a unique, sculptural charm to desks, shelves, and sunny windowsills, and its compact size makes it a great addition to any indoor plant collection.

🌵 Care Tips:

Light:
Loves bright, direct sunlight. Place it near a sunny window or outdoors in full sun. Insufficient light may cause stretching or a loss of its compact shape.

Water:
Water sparingly. Allow the soil to dry out completely between waterings. During winter, reduce watering even further, only watering once the soil has been dry for a while.

Humidity:
Does best in dry environments. No need for misting—low humidity is ideal for cacti.

Temperature:
Prefers warm temperatures between 18°C to 29°C (65°F to 85°F). Protect from frost and cold drafts; it’s not frost-tolerant.

Soil:
Use a cactus/succulent mix with excellent drainage. You can amend with perlite or coarse sand for extra airflow.

Fertiliser:
Feed with a diluted cactus fertiliser once a month during the growing season (spring to early autumn). Do not fertilise in winter.

Pet Friendly:
⚠️ No. Like many cacti, Brain Cactus has small spines that can irritate pets and curious hands. Place out of reach of children and animals.
