About Hibiscus sturtii Hook.
Hibiscus sturtii Hook., commonly known as hill hibiscus, is a small understory shrub that grows up to 60 cm (24 in) high, and is occasionally prostrate. Its grey-green leaves are thickly covered in star-shaped hairs, with shapes ranging from egg-shaped to lance-shaped or oblong-lance-shaped. The leaves measure 2–5 cm (0.79–1.97 in) long, have a rounded apex, and grow from a petiole that is 4–18 mm (0.16–0.71 in) long. Its flowers have pink, mauve, or white petals that may bear a dark spot at the base. The corolla of the flower is 1.5–2.5 cm (0.59–0.98 in) long. The calyx lobes are lance-shaped or triangular, and measure 8–13 mm (0.31–0.51 in) long, while the peduncle is 6–33 mm (0.24–1.30 in) long. Flowering occurs from autumn through to spring. The fruit is a densely hairy globular capsule that is 8–10 mm (0.31–0.39 in) long. Hill hibiscus grows in a variety of soils and locations across mainland Australia, with the exception of Victoria.
