The flowers of Adromischus triflorus grow on short pedicels, spaced in the inflorescence on a long erect flower stem that may branch.
Each bisexual flower comprises a short calyx with small, pointed lobes near the base of the long corolla. The bud is maroon on the outside of the corolla and cylindrical but for longitudinal folds that disappear in the open flower. The corolla may become green or yellowish green outside, sometimes speckled or suffused in faint maroon-red.
In the open flower the five lanceolate to triangular corolla lobes spread around the mouth of the 1 cm long tube. They are white on the inside with pink tips, sometimes faintly pink all over. In picture the elongated lobe tips curl slightly, also in the short, hair-like apical protrusion.
There are tiny, club-shaped, fleshy growths visible in the flower throat called trichomes. The yellow anthers are visible in the throat but not exserted (Frandsen, 2017; Vlok and Schutte-Vlok, 2015; iNaturalist; http://llifle.com; http://pza.sanbi.org).
