Cultivation: Suitable for the home or a greenhouse, During winter's rest period they should be dry and cool, it is frost resistant to -4°C but  thrives best with additional heat,  they like only a short winter's rest. If the soil is allowed to be dry for too long root loss could follow but equally the same result would occur if the plants are both wet and cold, rot easily if the substrate is wet and cold. Prefers filtered bright light with ample airflow. Will enjoy regular water in summer. Best if watered with rain water, an acid compost and iron feed help to delay the onset of basal corking. A well grown plant is a fresh glossy grass- green, contrasting with reddish spines.
Reproduction:  Usually by seeds as it seldom produces offsets.
