Prostanthera, commonly known as mintbush or mint bush, is a genus of flowering plants of the family Lamiaceae. There are about 90 species within the genus, all of which are endemic to Australia. The word Prostanthera is derived from the Greek for an appendage. Within the flowers are small spur-like appendages on the anthers.
These plants are bushy, evergreen shrubs, usually with strongly aromatic leaves, and 2-lipped, 5-lobed flowers. They are cultivated as ornamentals and for essential oils and spices. All require varying degrees of winter protection in temperate regions, and are usually grown under glass. Prostanthera species are used as food plants by the larvae of hepialid moths of the genus Aenetus including A. eximia and A. ligniveren.
