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 the latter part of spring (Marais, (Ed.), 2017; Manning, 2007; Bean and Johns, 2005; iNaturalist).
