Aspalathus pedunculata flowers grow solitary on the tips of small side-shoots. They may be plentiful in season, which lasts from before midwinter to early summer. The specific name, pedunculata, recognises these longish floral branchlets.
The lobes of the hairy calyces end in narrowly pointed tips. The light-yellow corollas are silky on the outsides of the banner, keel and wing petals. The broad banner is markedly longer than the keel. The flowers are about 1 cm long (Vlok and Schutte-Vlok, 2015; Bond and Goldblatt, 1984; JSTOR; iNaturalist).
