Lemon Tea Tree — Lemon-medicinal, Citral-fresh, Tea-tree-clean
Botanical name
Leptospermum petersonii
Also known as
Lemon-scented Teatree, Lemon Scented Tea Tree
Main flavour compound
Citral (70-80%)
Part used
Dried leaf
Method of cultivation
Small evergreen tree or shrub of the Myrtaceae family, endemic to eastern Australia (mostly Queensland and northern NSW). Closely related to the standard tea tree (*Melaleuca alternifolia*) but with very different chemistry — Lemon Tea Tree is citral-dominant rather than terpinen-4-ol-dominant, which gives it a clean lemon character with much less of the medicinal-camphor that defines common tea tree. Commercial plantation cultivation has expanded in the past 30 years.
Commercial preparation
Leaves are harvested by coppicing or selective cutting, gently dried to preserve citral, and either sold whole or steam-distilled for essential oil. The oil is 70–80% citral — one of the highest natural citral concentrations in any Myrtaceae species (second only to Lemon Myrtle).
Non-culinary uses
Essential oil for natural cosmetics, soap and aromatherapy; insect-repellent applications (citral has well-documented antimicrobial activity); natural cleaning products; some traditional Indigenous medicinal use.

Lemon Tea Tree — Leptospermum petersonii — is a small evergreen tree or shrub of the Myrtaceae family, endemic to eastern Australia. Despite the common name including "tea tree," it is a different genus from the common medicinal tea tree (Melaleuca alternifolia) — they are botanical cousins in the same family but with very different essential-oil chemistry. Lemon Tea Tree's leaves contain 70–80% citral, giving them a clean lemon-citral aroma far more pronounced than common tea tree's medicinal-camphor profile. [source]

The standard form — crumble lightly to release the citral.

Region of cultivation

Lemon Tea Tree — growing regions

Lemon Tea Tree is native to Australia, Australia — eastern Australian coastal Queensland and northern NSW, with secondary growing regions in Plantation cultivation expanding across temperate eastern Australia. |

Spice Story

Lemon Tea Tree sits in the citral-rich Myrtaceae family of Australian native botanicals — alongside Lemon Myrtle (Backhousia citriodora) and Honey Myrtle (Melaleuca teretifolia) — three species that together make Australia the world's largest commercial source of natural citral. Lemon Tea Tree has been used by Indigenous Australians for tens of thousands of years across its eastern Australian range, and modern commercial plantation has expanded substantially over the past 30 years to meet international demand for natural lemon-aromatic ingredients. In gin, Lemon Tea Tree provides a cleaner lemon character than imported lemon and a different lemon profile from Lemon Myrtle — useful when layering native citrus botanicals.

Gin Creativity

Lemon Tea Tree brings clean lemon-citral character with a slightly more "green" leafy edge than Lemon Myrtle. A full sachet pushes a gin firmly into native-lemon territory; a half-sachet provides quiet lemon brightness that integrates with juniper. Pair with Lemon Myrtle for layered citral, or with Pepperberry and Native Lemongrass for a bush-spice profile.

Citral (70–80% — neral + geranial) dominates the leaf oil, providing the bright lemon character. Citronellal layers a softer rose-citrus note. Linalool contributes a quiet floral lift. Alpha-pinene adds a faintly resinous backbone that bridges Lemon Tea Tree to juniper. Cool extraction preserves the citral.
