Calytrix aurea

Calytrix aurea is a shrub that typically grows to a height of 0.2–1.3 m (7.9 in – 4 ft 3.2 in). Its leaves are elliptic, lance-shaped or linear, 5–12 mm (0.20–0.47 in) long and 1.5–5 mm (0.059–0.197 in) wide on a petiole up to 0.5–2 mm (0.020–0.079 in) long. There is a stipule 0.5 mm (0.020 in) long at the base of the petiole. The flowers are arranged singly in clusters, each flower on a peduncle 0.5–1 mm (0.020–0.039 in) long. The floral tube has 10 to 12 ribs and is 9–13 mm (0.35–0.51 in) long. The sepals are joined at the base, 2.0–2.5 mm (0.079–0.098 in) long with an awn up to 17 mm (0.67 in) long. The petals are yellow, egg-shaped to elliptic, 6.5–10 mm (0.26–0.39 in) long and 3.0–4.5 mm (0.12–0.18 in) wide, and there are about 25 to 55 yellow stamens in 2 or 3 rows. Flowering occurs from October to December or January.

This species of Calytrix grows in heath on sand, often over laterite and occurs between the Arrowsmith River area and Perth, in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.

This plant performs best in a sunny position and requires a well-drained situation, such as a built-up rockery. Plants are readily propagated by cuttings.
