The stalked leaves of Pelargonium magenteum are heart-shaped to rounded, sometimes shallowly lobed and always coarsely toothed. The grey-green, sometimes yellow-green and velvety blades have veins sunken on top, radiating from the leaf base. Leaf diameter is about 2 cm.
The leaf stalks and pinkish upper stems of the softly woody plant are also faintly hairy. Small, narrow stipules are visible in picture at leaf petiole bases (Vlok and Schutte-Vlok, 2015; Manning and Goldblatt, 1997; Bond and Goldblatt, 1984).
