About Dianella longifolia R.Br.
Dianella longifolia R.Br. is a rhizomatous, perennial herb that forms tufts reaching around 1.5 m (4 ft 11 in) in height, with stems measuring less than 10 cm (3.9 in) long. Its leaves are folded lengthwise and grass-like, 20–80 cm (7.9–31.5 in) long and 2–25 mm (0.079–0.984 in) wide, with a sheath that ranges from rounded to keeled. The inflorescence of this species is longer than its leaves. The individual flowers are pale blue, white, or greenish, well spaced apart from one another, and each grows on a pedicel 7–16 mm (0.28–0.63 in) long. There are three outer tepals 6–10 mm (0.24–0.39 in) long, and inner tepals 5.5–9 mm (0.22–0.35 in) long; every tepal has five veins. The stamens have filament swellings 1–2.3 mm (0.039–0.091 in) long, and yellow anthers. Flowering takes place in spring and summer, and the fruit produced is a pale blue berry 3–7 mm (0.12–0.28 in) long. This species, commonly called blueberry lily, is widespread and common in non-arid regions of Australia, including the Kimberley region, eastern and southern Australia, and northern Tasmania.
