Prostanthera violacea is a slender, strongly aromatic shrub that typically grows to a height of 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 long and wide on a petiole long. The flowers are borne singly in leaf axils, each flower with bracteoles long under the sepals. The sepals are long forming a tube long with two lobes, the upper lobe about long. The petals are mauve to bluish, often with white tips, long. Flowering occurs in spring.[1]
Prostanthera violacea was formally described in 1810 by Robert Brown in his treatise Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[2] [3]
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.
