By far one of the most rare and desirable of all succulents it forms in age more of a bush than a small tree (like a dwarf baobab). The bizarre succulent stem may achieve a diameter of 2,4 metres. Apparently contradicting its strange appearance, the tree produces a mass of attractive pink flowers in the winter, as a result of which it is also known in the local language as the 'desert rose'.
