Astroloba robusta

A stout, glossy-leaved Astroloba of the Foliolosa group, described from the Great Karoo around Prince Albert, Klaarstroom and Beaufort West. It forms stiff columns of sharp triangular leaves and grows slowly. Treat it like a hard-leaved Haworthiopsis: bright light, mineral soil, careful summer watering and cool winters.
