Native Oregano — Mint-oregano, Citrus-bright, Herb-sharp
Botanical name
Prostanthera rotundifolia
Also known as
Round-leaf Mint Bush, Australian Mint Bush
Main flavour compound
1,8-Cineole
Part used
Dried leaf
Method of cultivation
Aromatic shrub of the Lamiaceae (mint) family, native to south-eastern Australia (Victoria, NSW, Tasmania, ACT). The plant grows 1–2 metres tall, with small rounded aromatic leaves and clusters of small purple flowers in spring. The genus *Prostanthera* is the largest and most chemically diverse of the Australian native mint bushes — over 100 species, with substantial chemotypical variation in their essential oils. "Native Oregano" specifically refers to *P. rotundifolia* in the bushfood trade because of its distinctive oregano-mint-citrus character.
Commercial preparation
Leaves are harvested from cultivated or sustainably wild-collected plants, gently dried, and either sold whole or cracked. Most production is small-scale and artisanal.
Non-culinary uses
Essential oil for natural cosmetics and aromatherapy; ornamental garden plant in temperate Australian gardens; some traditional Indigenous medicinal use.

Native Oregano — Prostanthera rotundifolia, also called Round-leaf Mint Bush — is an aromatic shrub of the mint family, endemic to the temperate woodlands of south-eastern Australia. The plant grows 1–2 metres tall, with small rounded leaves and clusters of small purple flowers in spring. Despite its common name, Native Oregano is not closely related to Mediterranean oregano (Origanum vulgare) — they share a family (Lamiaceae) but are in different genera. The "oregano" name in the bushfood trade comes from the leaf's distinctive flavour profile, which combines oregano-like herbaceous depth with a mint-cool top note and a faint citrus brightness — a combination unique to P. rotundifolia.

Native Oregano is native to Australia, Australia — Victoria, NSW, Tasmania, ACT (temperate forest and woodland), with secondary growing regions in Small plantation cultivation across temperate southern Australia. |

Spice Story

The genus Prostanthera is an entirely Australian native botanical group — over 100 species, all aromatic, all chemically distinct from imported Mediterranean herbs. Native Oregano is one of a small handful of Prostanthera species (alongside Native Thyme, Native Rosemary/Sage and Balm Mint Bush) that have entered the modern Australian bushfood trade as native alternatives to Mediterranean kitchen herbs. The genus has been used by Aboriginal peoples across south-eastern Australia for tens of thousands of years; commercial cultivation is much more recent and remains small-scale. In gin, Native Oregano provides a clearly Australian alternative to imported Mediterranean oregano.

Gin Creativity

Native Oregano brings mint-oregano herbaceous character with a faint citrus brightness. A full sachet pushes a gin firmly into clearly native-herb territory; a half-sachet provides quiet herbaceous depth that integrates with juniper. Pair with Native Thyme and Native Rosemary/Sage for a fully native herb-garden profile, or with Lemon Myrtle for a brighter bush-spice blend.

Pairs well with

1,8-Cineole provides the cool mint-eucalypt edge characteristic of the Prostanthera genus. Linalool adds the soft floral lift familiar from coriander and lavender. Beta-pinene layers a resinous backbone that bridges to juniper. Limonene contributes a citrus brightness. Cool extraction preserves the bright top; warm extraction develops the deeper herbaceous body.
