Crassula inanis

A soft, low, spreading Crassula of the eastern South African summer-rainfall region. It reaches the high Drakensberg in Lesotho and extends north to Uganda. Unlike most cultivated Crassulas it is a plant of moist ground, so it needs more water in summer and a cold, dry winter rest.

Where it grows wild

It is usually described as growing in damp places such as seepage areas, stream banks and wet grassland or rock ledges. That fits the high summer rainfall at the measured sites. No species-specific habitat notes were confirmed in the sources checked this round.

The records that give an elevation run from 610 to 2400 m, with a median of 2400 m, so many populations are montane.
