EUCALYPTUS LEMON SCENTED IRONBARK
- Botanical name
- Eucalyptus staigeriana
- Also known as
- Lemon-scented Ironbark, LSIB, Lemon Ironbark, Eucalyptus Lemon Ironbark
- Main flavour compound
- 1,8-Cineole (~35%)
- Part used
- Dried leaf
- Method of cultivation
- Small ironbark tree of the Myrtaceae family, endemic to a tightly restricted range in the Palmer River area of Cape York Peninsula in far north Queensland — the Maytown–Palmer River–Maitland Downs hill country. The species reaches around 12 metres tall, forms a lignotuber (and so coppices well after cutting), and prefers full sun on well-drained soil. Unusual among eucalypts for combining strong citral content (giving it a clear lemon character) with the more typical cineole eucalypt backbone.
- Commercial preparation
- Leaves are harvested from cultivated plantation or sustainable wild stands, gently dried, and either sold whole for distilling or steam-distilled for essential oil. Fresh leaves yield 2.9–3.4% essential oil — high by eucalypt standards.
- Non-culinary uses
- Essential oil for flavouring, perfumery and aromatherapy; the lemon-and-eucalypt character makes it particularly useful in fragrance work; insect repellent applications.
Eucalyptus Lemon Scented Ironbark — Eucalyptus staigeriana, often abbreviated as LSIB — is a small ironbark tree of the Myrtaceae family, endemic to a remarkably small native range in far north Queensland: the Palmer River, Maytown and Maitland Downs hill country of Cape York Peninsula. [source] The species grows to about 12 metres with a distinctive dark, deeply-furrowed ironbark trunk. What makes LSIB botanically interesting is its essential oil chemistry: unlike most eucalypts, which are dominated by 1,8-cineole, LSIB combines moderate cineole (around 35%) with substantial citral content (neral and geranial together, around 22%) plus geraniol and nerol — giving the oil a distinctly lemon-and-eucalypt character that no other commercial eucalypt matches.

Region of cultivation
Eucalyptus Lemon Scented Ironbark is native to Australia, Australia — Cape York Peninsula, Queensland (Palmer River, Maytown, Maitland Downs), with secondary growing regions in Limited plantation cultivation in northern Queensland. |
Spice Story
LSIB is one of a small handful of native Australian eucalypts that have moved from regional curiosity to commercial essential-oil production in the past few decades. The narrow native range — restricted to one geological pocket of Cape York — means commercial supply depends on small plantation operations, and LSIB remains less widely available than the more widely-distributed blue mallee or blue gum. Its dual character (eucalypt-and-lemon) makes it particularly valuable in fragrance and flavour work, and it has begun to appear in Australian craft gin where distillers want both eucalypt and citrus character from a single botanical.
Gin Creativity
LSIB is one of the most distinctive Australian botanicals available — pushing a gin into clearly lemon-eucalypt territory in a way no other single ingredient can. A full sachet creates an explicitly native lemon-eucalypt gin; a half-sachet adds a quietly complex aromatic that integrates with juniper. Pairs particularly well with lemon myrtle (citral-on-citral, doubled brightness) or with pepperberry and native lemongrass for a bush-spice profile. Avoid pairing with very heavy florals — LSIB's citrus brightness gets buried.

The dual-character chemistry is what distinguishes LSIB from other eucalypts. 1,8-Cineole (about 35%) provides the cool eucalypt backbone. Neral and geranial (together about 22%) — the two isomers of citral — provide the bright lemon character. Alpha-phellandrene (about 9%) adds green-herbaceous depth. Methyl geranate layers a sweet floral lift. [source] The citral is the more heat-sensitive component; cool extraction preserves the lemon brightness, while warm extraction emphasises the cineole and the methyl geranate floral notes.

- Lemon-eucalypt Spritz — LSIB gin, prosecco, soda, lemon zest.
Release The Flavour
- Cool extraction — preserves the bright citral lemon character.
- Crumble gently — exposes the oils without bitterness.
- Source matters — genuine Cape York-origin LSIB has more citral than plantation production.
- Time — short extractions favour the lemon top; longer extractions develop the cineole body.
