A distinctive barrel-shaped cactus with prominent ribs and attractive curved spines. Mature plants develop a striking wooly cephalium, making this species a fascinating addition to any collection!
Keep in a place receiving plenty of daylight. Water sparsely - once in 5-6 days in summer. Reduce watering significantly in winter - likely just twice or thrice in a month. Never water when the soil is moist. Use a well draining cactus potting mix, preferably Cinder.
