The flowers are arranged in loose groups 20–180 mm (0.79–7.09 in) long, the sepals 0.5–1.2 mm (0.020–0.047 in) long and the petals 2–3 mm (0.079–0.118 in) long. Flowering occurs from September to November and the fruit is oval to more or less spherical, 5–6 mm (0.20–0.24 in) long containing a shiny black seed.[2][3][4]
