The partly open Acmadenia heterophylla flower is deep pink, the petals still uneven in their development. The star-shape of the corolla arrives a little later. Petal colour may fade with age.
The anthers are gland-tipped, the ovary covered in a fleshy disc. The flowers grow in small groups at stem-tips. Flowering may occur at any time throughout the year, profusely in winter and spring (Bond and Goldblatt, 1984; iNaturalist; http://pza.sanbi.org).
