Description

Dianella revoluta is a tufted, perennial herb with stems less than 15 cm (5.9 in) long and touching or up to 30 cm (12 in) apart. The leaves are folded lengthwise and grass-like, 15–85 cm (5.9–33.5 in) long and 3–23 mm (0.12–0.91 in) wide. The flowers are blue to violet and are arranged in goups of two to nine, each flower 10–20 mm (0.39–0.79 in) wide on a pedicel 5–35 mm (0.20–1.38 in) long. The three sepals are 5.5–10 mm (0.22–0.39 in) long with five to seven veins and the petals 5.2–9.5 mm (0.20–0.37 in) long with five veins. The stamen filaments are 0.6–2.3 mm (0.024–0.091 in) long and bright yellow, the anthers 2.5–4.5 mm (0.098–0.177 in) long and pale brown to almost black. Flowering mainly occurs from spring to early summer and the fruit is a blue to purple berry, 4–10 mm (0.16–0.39 in) long.
