The Cyphostemma oleraceum inflorescence grows many-flowered in a large, flat-topped panicle on a sturdy peduncle above the leaves.

The small, bisexual flowers are yellow, their four petals falling early and the curving pedicels red. Flowering happens during spring and early summer.

The red fruits are ellipsoid to oblong, containing a high level of oxalic acid that makes them unpalatable (Hardy and Fabian, 1992; Germishuizen and Fabian, 1982; iNaturalist).
