The sometimes tufted, lower leaves of Pelargonium incarnatum are triangular to palmate and deeply lobed or unevenly scalloped, the surfaces rough. These leaves grow on long stalks, the tips often erect, the leaf bases here about straight or square.

Upper leaves found on bigger plants tend to be more deeply incised. Leaf colour is green to reddish (Manning, 2007; Bean and Johns, 2005; iNaturalist).
