Cultivation: 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 assumes a grey-green colouring
between watering, is perfectly natural and doesn’t cause any damage.

flat natural look, or partial sun. |
