The flowers of Adromischus triflorus grow on short pedicels, spaced in an 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 and cylindrical but for longitudinal folds that disappear in the open flower, becoming green or yellowish green, sometimes speckled or suffused in faint maroon-red. The bud may curve down near its tip.
The five lanceolate to triangular corolla lobes of the open flower spread at 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.
There are tiny, club-shaped, fleshy growths visible in the 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).
