Pelargonium salmoneum leaves

The roundly palmate leaves of Pelargonium salmoneum are heart-shaped at the base, growing on petioles from less than 2 cm to 4 cm long. Broad, ovate stipules up to 13 mm long are present next to the petiole bases. The upper surfaces are concave. The leaf margins may be somewhat lobed and are unevenly, shallowly toothed. The blades are bright green to yellowish green and faintly hairy with sunken veins that radiate from the base and branch sparsely.

When there are dark red zonal marks on the leaves, the question might arise whether the plant should be called P. zonale. 

The plant is evergreen, in some conditions tending to deciduous (iNaturalist; https://pza.sanbi.org; https://www.randomharvest.co.za).
