Description
Prostanthera violacea is a slender, strongly aromatic shrub that typically grows to a height of 0.5–2 m and has densely hairy branches. The leaves are more or less round but usually appear egg-shaped because the edges are rolled under. The leaves are 2–6 mm long and wide on a petiole 0.3–1 mm long. The flowers are borne singly in leaf axils, each flower with bracteoles 1.5–2 mm long under the sepals. The sepals are 4–5 mm long forming a tube 1.5–2 mm long with two lobes, the upper lobe about 2 mm long. The petals are mauve to bluish, often with white tips, 7–8 mm long. Flowering occurs in spring.

Taxonomy
Prostanthera violacea was formally described in 1810 by Robert Brown in his treatise Prodromus Florae Novae Hollandiae et Insulae Van Diemen.

Distribution and habitat
Violet mint-bush grows in forest, including rainforest, often in gullies or near watercourses, and is found on the coast and tablelands of south-eastern New South Wales.
