The flowers of Oxalis incarnata are white to pale lilac or pink. There are five small, pale green sepals around the corolla base, their pointed tips veering out.
The five petals form a funnel-shaped tube before spreading their widened, slightly asymmetrical lobes. The corolla is lemon yellow in the throat with dull green lines ascending from the base for a short distance.
Flowering happens from spring to summer, in some parts to after mid-autumn (Moriarty, 1997; Bond and Goldblatt, 1984; iNaturalist).
