The fragrant, feathery leaves of Pelargonium abrotanifolium are divided into three to five segments and then further into, narrowly oblong and blunt-tipped lobes. These leaf parts are arranged in a somewhat fan-shaped structure, the leaves greyish from a dense covering of soft, short, white hairs. Leaf length is about 15 mm.
Small, lance-shaped stipules are present at the petiole base.
The specific name, abrotanifolium, refers to the resemblance of the leaves to those of Artemisia abrotanum, a relative of wilde-als (Vlok and Schutte-Vlok, 2015; Bond and Goldblatt, 1984; iNaturalist).
