The flower buds are arranged in leaf axils in groups of three on an unbranched peduncle Шаблон:Cvt long, the individual buds sessile or on very short pedicels. Mature buds are oval to spindle-shaped, glaucous, Шаблон:Cvt long and Шаблон:Cvt wide with a rounded operculum. Flowering occurs in July or November and the flowers are white or yellow.
