Euphorbia hypogaea

A dwarf, largely underground succulent Euphorbia of the high Karoo, with a thick buried stem from which short branches emerge at soil level. It comes from hot, dry, very sunny plateaus at 1,150–1,800 m with near-freezing winter nights, so it wants full sun, a gritty deep pot, summer water and a cold, dry winter.

Where it grows wild

Records lie on the Great Karoo plateau of the Northern and Western Cape, in open stony karroid shrubland where dwarf succulents grow almost flush with the ground in full sun.

Climate sites sit between about 1,160 and 1,790 m; specimen elevations are not recorded.
