The bright yellow flowers of Aspalathus hirta grow scattered on or near the tips of short sideshoots, solitary or in small clusters. The calyces are hairy, their lobes needle-like and sharp-tipped as the leaflets.
The wing and keel petals are of equal length and hairless. The large, recurving and centrally pleated banners are grey-haired on the back, parallel-veined on the front in the photo. The flowers are up to 15 mm long.
Flowering happens in spring and early summer (Curtis-Scott, et al, 2020; Vlok and Schutte-Vlok, 2015; Manning, 2007; Bond and Goldblatt, 1984; iNaturalist).
