Euphorbia exilis

A small, slender Euphorbia from the winter-rainfall semi-desert of Namaqualand and the Knersvlakte in South Africa. Grow it like other dwarf Cape succulents: very bright light, cool moist winters for growth and a dry, hot summer rest.

Where it grows wild

Arid shrubland (succulent Karoo) on stony or sandy flats and slopes; inferred from the record sites and the genus, since species-specific notes are thin.

Mostly low elevations of about 200–900 m; one record gives 3,000 m, which is not plausible for this region.
