Cerochlamys pachyphylla flowers grow solitary or in groups of up to three. They are short-stalked, opening closely above the leaves. The five sepals are nearly identical.
Flower colour is mostly purple-pink, while white flowers are occasionally seen and yellow ones rarely. Both the latter forms are known around Calitzdorp and noted for wavy leaf margins. The narrow petals grow in up to three whorls, their bases often paler than their tips. The petals spread to 3 cm in diameter.
There are numerous staminodes around the stamens, filaments lacking anthers. The stamens bear yellow anthers. Each flower has five pointed stigmas as well as five nectar glands.
The species blooms from late autumn through winter. The white flowers arrive earlier than the other forms. Flowers last long, opening in the morning for the day (Vlok and Schutte-Vlok, 2015; Smith, et al, 1998; iNaturalist).
