Cultivation:
Its qualities and ease of cultivation justify its being an old favourite.  It doesn't requires any special treatment, but needs as much light as possible without burning the plant, in order to encourage the heaviest spine formation. Water regularly in summer, keep dry in winter.
Frost tolerance: -4° C.
Propagation:
Seeds or offsets.
