Aloe mutabilis is closely related to A. arborescens, sometimes classified as just another form. Its spectacular feature is the clinging to steep cliff edges, hanging high above water or over deep, shady ravines. There is said to be a form in Mpumalanga bearing pure red flowers, i.e. the perianths do not turn yellow upon opening
As the specific name aculeata says, it is prickly! The big single rosettes of Aloe aculeata are in winter adorned with impressive yellow or orange inflorescences. Single raceme flowers appear on the younger plants and branched panicles on mature ones. This Aloe is common in parts of the northern provinces of South Africa, particularly in Mpumalanga and Limpopo near Lydenburg and Ohrigstad, as well as over the border in Zimbabwe and Botswana.
