Care at a glance
Light
Full sun. Demands several hours of direct sunshine daily to stay compact and develop intense powdery blue coloration.
Watering
Very sparse watering; drench gravelly succulent mix only after extended dry periods. Withhold water in winter.
Conditions vary with pot, season and location. Always check the mix and your plant's response.
How to identify it
Striking solitary rosette of thick, rough-textured greyish-blue succulent leaves armed with fierce dark marginal teeth.
Environment and placement
Hot, arid and well-ventilated (12-32 °C / 54-90 °F). Hardy against light frost if substrate is bone dry.

Potting mix and feeding
Prioritise a very free-draining mix and a pot with holes. Heavy mix that remains wet for weeks raises root risk.
Feed sparingly during active growth if needed; do not fertilise a plant weakened by overwatering.
Problems to check
Center heart rot if water pools in the crown; root rot from water-retentive clay soils.

ASPCACommon question
Why does it feel rough like sandpaper?
Microscopic epidermal papillae give it a raspy texture, evolved to capture and direct nighttime fog and dew to its roots.
