The flowers of Delosperma peersii are small and white, sometimes pink. Their five sepals are notably unequal. Flowers grow solitary or in groups of up to three.
One row of soft, round-tipped petals spread around the flower centre, the petal-shape oblong to oblanceolate. Flower diameter is about 15 mm.
The stamens form a cone in the centre, surrounded by antherless staminodes. Five nectar glands are present in the flower base.
Flowering happens in spring and early summer (Vlok and Schutte-Vlok, 2015; Smith, et al, 1998; iNaturalist).
