The almost radially symmetrical flowers of Pelargonium incarnatum are pale pink or nearly white to salmon-pink or cerise with a reddish eye inside red and white rings. The "almost" means that two of the five round-tipped petals are sometimes smaller. The five sepals are narrow and hairy.
The floral tube, a shallow depression, is shorter than the pedicel; no hollow corolla tube is present in this species. Flower diameter is about 2 cm, the pedicels shorter than the peduncle. There are five fertile and five sterile stamens.
Flowering happens from late winter to early summer, peaking in a part of spring (Manning, 2007; Bean and Johns, 2005; iNaturalist).
