The white or dull yellow flowers of Wahlenbergia albens grow solitary or slightly clustered from leaf axils. There is a longish rigid pedicel below the calyx that consists of five leaf-like sepals.
The corolla is star-shaped, its five long, narrow petals recurving gracefully in their upper parts. The corolla tube is only about 1 mm long, the petals free to nearly the base. The outsides of the petals have a sparse covering of soft, whitish hairs, visible in the photo. Flower diameter is about 5 mm.
The erect style is tall upon the about globose ovary, the stigma pale blue. The five stamens are short and hard to see (Bond and Goldblatt, 1984; iNaturalist; http://worldfloraonline.org).
