The simple, ascending leaves of Delosperma lebomboense grow opposite on reddish stems, the internodes sometimes long.
The thickly succulent leaves are short-stalked to about stalkless. They are ovate in shape to somewhat elongated and flat to concave, or shallowly channelled above. The keeled leaves are mostly about triangular in cross-section, usually with a small mucro protruding from the leaf-tip that may be curved back. The margins may be whitish on the leaves of some plants (Smith, et al, 2017; Hardy and Fabian, 1992; iNaturalist).
