We are, of course, seeking photos of species not yet shown in the gallery but not only that, we are also looking for better pictures than those already present.
Read More... Cultivation and Propagation: This species is fairly robust and easy to grow. Watering should be rather infrequent to keep plant compact. The fact that the plant retracts into the soil and assume a grey-green colouring between watering, is perfectly natural and doesn’t cause any damage. Hardy to -4°C for a short period.
Exposures: Full sun where it obtains a flat natural looking or part sun.
