The tufted, stalked leaves of Pelargonium luteolum are palmate, narrowly dissected into oblong to oblanceolate lobes. The dark green to dull green blades are finely hairy, the lobes folding in along their midribs. The margins are entire, the tips bluntly pointed to rounded.
The leaves are about 4 cm long, 3 cm wide, while lobes may be up to 5 mm wide.
The leaves are usually dry by the time the plant flowers (Vlok and Schutte-Vlok, 2015; Bond and Goldblatt, 1984; iNaturalist).
