Flowerheads of Garuleum bipinnatum are carried solitary or in lax corymbs on variably long stalks. The flowerhead has a bell-shaped involucre comprising two or three rows of bracts. It becomes 2,5 cm wide and 6 mm long. The (female) ray florets are mauve, blue or occasionally white. The central disc is yellow.
Flowering usually occurs in spring, although the plant in picture had finished flowering for the season by August (Vlok and Schutte-Vlok, 2010; Shearing and Van Heerden, 2008; www.plantzafrica.com).
