About Halgania cyanea Lindl.
Halgania cyanea is a small, typically dense perennial plant with an upright height of 20 to 40 cm (7.9 to 15.7 in) and a spreading growth habit that can reach up to 2 m (6 ft 7 in) wide. Its leaves are dull green, narrow elliptic or linear in shape, measuring 4–20 mm (0.16–0.79 in) long and 2–4 mm (0.079–0.157 in) wide. The leaves are flattened, have glandular hairs on the upper surface, toothed edges, and are almost sessile. Flowers are bright blue, or rarely white, 10–12 mm (0.39–0.47 in) in diameter. They usually grow singly, or in clusters of up to 3 in a terminal inflorescence on a pedicel 2–10 mm (0.079–0.394 in) long. The calyx is 3–4 mm (0.12–0.16 in) long, with lobes that are narrow-triangular or lance-shaped and equal in size. Flowering occurs mostly in summer, and may also happen sporadically throughout the year. The fruit is a brown drupe that contains one or two seeds. Commonly called rough halgania, this species grows in a wide variety of habitats including sandy loam, sand plains, mallee, and sand dunes across Western Australia, South Australia, Victoria, and the Northern Territory. In New South Wales, it is restricted to mallee communities only.
