Where it grows wild

Rock crevices on ledges and sheer east-facing quartzitic sandstone cliffs, frequently in cloud, within Lydenburg Mountain Grassland with Afromontane forest in the kloofs. Winter grass fires are frequent and the old leaf bases insulate the stems.

The description gives the altitude as "1,700 – 1200 m", evidently a typo; the only measured site is at about 2,080 m on Mount Anderson.
