Curio crassulifolius, commonly known as blue fingers, is a sprawling to matforming perennial. The leaf succulent reaches heights from 15 cm to 30 cm. Sometimes erect, the plants tend to topple over in wet conditions and creep.
Scientifically the plant used to be known as Senecio crassulifolius and Kleinia crassulifolia at different stages of dealings in botanical history. There is also an issue with the spelling of the specific epithet: some records have it as crassulaefolius, the same plant using an apparently older spelling.
The botanical names all indicate leaf resemblance with Crassula, as well as other family connections that are not altogether without some relevance, but the overriding connections according to latest information take precedence.
The species distribution is mostly southerly in the Western Cape, from the Cederberg to the southwest of the Eastern Cape as far as Kariega (Uitenhage). The photo was taken in the Salmonsdam Nature Reserve southeast of Stanford.
The habitat is dry, often karoid fynbos and renosterveld on rocky outcrops and ledges. The status of the plant population in nature is unknown, due to insufficient information.
These plants do well in gardens (Smith, et al, 2017; Bean & Johns, 2005; Wikipedia; http://pza.sanbi.org; http://redlist.sanbi.org).
