This juvenile Crassula expansa subsp. expansa plant is not complaining about its Little Karoo living conditions.
The about equal, banana-like, curved leaves grown in opposite pairs are decussate or perpendicular up the whitish branches.
Leaf colour can be green, dark purple or orange red, depending on the environmental conditions and fine-tuning in the leaf cell chemistry of the moment (Curtis-Scott, et al, 2020; Smith, et al, 2017; Vlok and Schutte-Vlok, 2015; iNaturalist).
