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 groups 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.[2][4][5][6]

Taxonomy

Dianella revoluta was first formally described in 1810 by Robert Brown in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[7][8]

Five varieties of D. revoluta are accepted by the Australian Plant Census:

  • Dianella revoluta var. divaricata (R.Br.) R.J.F.Henderson;[9]
  • Dianella revoluta var. minor R.J.F.Henderson;[10]
  • Dianella revoluta R.Br. var. revoluta R.J.F.Henderson;[11]
  • Dianella revoluta var. tenuis R.J.F.Henderson;[12]
  • Dianella revoluta var. vinosa R.J.F.Henderson.[13]

Distribution and habitat

Blueberry lily is common and widespread in all Australian states and the Australian Capital Territory but not the Northern Territory, growing in a wide range of habitats apart from very wet and very dry habitats.[4]

Uses

The berry of D. revoluta is reported to be edible.[14]

Cultural use

Dianella, Western Australia was named after this plant, which was plentiful in the area prior to the 1960s residential development.[15]
