Description

Small short-stemmed succulent with stretched alternating small items of 0.8 cm long. They are grey and green.
At the apex of articles are small bristles radiating around the center giving the appearance of a cactus areole.

The flowers look like daisies, but with petals dark red, worth the nickname "Desert Rose".

Cultivation

Sun exposure (but not too intense sun) and well drained soil.

Multiplication by division of clumps, cuttings is very uncertain because of the risk of rot.
