The leaf of Clivia mirabilis (in the middle of the picture) shows a median white striation as compared to the pure green leaves of other Clivia species.
Oorlogskloof Nature Reserve near Nieuwoudtville, Northern Cape, South Africa.
Sandstone talus screes below the cliffs of the Oorlogskloof Canyon, at about 900 m. Plants grow mainly in humus between cracks in sandstone talus of rock screes, either as solitary individuals or in small groups, in light woodland of Afromontane evergreen forests. Associated species such as Podocarpus elongates, Olea europaea ssp africana, Cassine schinoides, etc. provide further shade to Clivia mirabilis. Some plants also grow in full sun but these plants usually show signs of water stress with dried leaf tips. Most plants are shaded by cliffs till mid-morning, after which they receive full sun. The area where Clivia mirabilis endemic to experiences a semi-arid Mediterranean climate with a winter rainfall regime.
Adaptation to the Semi-Arid Climate:
C. mirabilis is a newly discovered species whose identity was only confirmed in February 2001. As the natural habitat of this species now enjoys maximum protection and no population is known outside the Oorlogskloof Nature Reserve, C. mirabilis remains extremely rare in cultivation.
In cultivation, C. mirabilis enjoys a humus rich medium and a half-shady environment. Taking into account its semi-arid habitat, the species would prefer a fairly dry condition during summer months.
