The flowers are fed at by a range of nectarivorous birds: mainly honeyeaters, including the New Holland honeyeater ("Phylidonyris novaehollandiae"), white-cheeked honeyeater ("P. nigra"), brown honeyeater ("Lichmera indistincta"), singing honeyeater ("Lichenostomus virescens"), tawny-crowned honeyeater ("Gliciphila melanops") and red wattlebird ("Anthochaera carunculata"). Lorikeets have also been observed feeding at the flowers, as have insects, including ants, bees, and aphids. Of these, evidence suggests that only birds are effective pollinators. Insects apparently play no role in pollination, since inflorescences do not form follicles when birds are excluded in pollinator exclusion experiments; and pollination by mammals has never been recorded in this species.
