Whether you are a home cook, a chef seeking a new flavour profile, or simply someone who loves a citrus lift in tea or dessert, Lemon Myrtle stands out for its crisp, sweet lemon notes and its clean, resinous aftertaste. In this guide, we explore Lemon Myrtle in depth—its botanicals, practical uses, cultivation tips, and the ways it has become a staple for flavour lovers across the British Isles and beyond.
What is Lemon Myrtle?
Lemon Myrtle, scientifically named Backhousia citriodora, is a evergreen shrub or small tree that belongs to the Myrtle family. The plant is renowned for its lemon-scented leaves, which contain a high concentration of essential oil, giving the herb its characteristic aroma. The leaves can be used fresh or dried, and the oil extracted from them is a potent ingredient in perfumes, cosmetics, and culinary preparations. When you encounter Lemon Myrtle in a recipe or on a spice shelf, you should think of it as a bright, citrus-forward herb with a clean finish and a gentle sweetness that avoids the sharp tang of other lemons.

Aroma and Flavour: Why Lemon Myrtle Delights the Palate
The aroma of Lemon Myrtle is instantly recognisable: a clean, citrus-forward scent with hints of eucalyptus and lime. The flavour mirrors this fragrance but also carries a soft sweetness and a light, almost vanilla-like undertone that makes it exceptionally versatile. Unlike some citrus herbs that can taste sour or bitter when overused, Lemon Myrtle provides a balanced lemony brightness with a smooth finish. This makes it an excellent partner for seafood, poultry, vegetables, and desserts alike.
How the flavour develops in cooking
When Lemon Myrtle is heated, the essential oils release gradually, producing a steady lemon aroma rather than a sharp burst. This allows cooks to build layers of citrus without overwhelming other ingredients. Fresh leaves lend a vibrant intensity, while dried leaves contribute a subtler, more contemplative note. For beverages, Lemon Myrtle can brighten teas, cordials, and cocktails without the astringency that some lemon flavours bring.
Origins and Traditional Uses
Lemon Myrtle has a long history in Indigenous Australian cuisine and medicine. Aboriginal communities have long valued its flavour and scent for food preservation, healing applications, and ceremonial uses. Early European settlers were impressed by its intense aroma and began cultivating the plant, which is now grown in various climates around the world, including temperate regions where growing conditions are cooler. The modern culinary scene has embraced Lemon Myrtle as a distinctive ingredient that can stand up to bold cooking while still letting the lemon character shine through.
Traditional preparation and utilisation
Historically, Lemon Myrtle leaves were dried for later use or pounded to release their essential oils. The plant was sometimes used in teas, infusions, and as a fragrant seasoning for roasted meats and stews. Contemporary enthusiasts continue these traditions, while also experimenting with fresh leaf preparations and modern extraction techniques for essential oils and flavour pastes.
Culinary Uses of Lemon Myrtle
Lemon Myrtle is a versatile herb that can be incorporated into many styles of cooking. Below are practical ideas for bringing the bright flavour of Lemon Myrtle into your kitchen.
Fresh leaves and drying for later use
Fresh Lemon Myrtle leaves offer the most immediate lemon aroma and are ideal for garnishing or infusing at the end of cooking. Drying leaves gently helps preserve essential oils for longer storage. When using dried leaves, crush them lightly to release their aroma before adding to dishes. A little goes a long way; start with a pinch or two and adjust to taste.
Pairings that sing with Lemon Myrtle
The clean citrus notes of Lemon Myrtle pair beautifully with:
- Seafood: prawns, white fish, and scallops
- Poultry: chicken and turkey
- Vegetables: zucchini, green beans, peas, and asparagus
- Sweet dishes: berries, cheesecake, pavlova, and citrus sorbets
- Grains: rice, quinoa, bulgur, and couscous
- Sweeteners: honey and maple syrup
Recipes to try at home
Here are a few approachable ideas to help you begin experimenting with Lemon Myrtle in everyday cooking.
Herbed Lemon Myrtle Crusted Salmon
Coat a fillet with a light mix of breadcrumbs, finely chopped Lemon Myrtle leaves, garlic, and olive oil. Roast until just cooked through, and serve with a fresh herb salad and lemon wedges. The citrus fragrance will intensify as the salmon rests, making this a crowd-pleasing dish with minimal effort.
Lemon Myrtle Tea
Infuse fresh leaves in hot water for five minutes. Add a touch of honey or a slice of lemon for a gentle, fragrant beverage that can be enjoyed hot or iced. A sprig of mint can also complement the flavours beautifully.
Beurre blanc with Lemon Myrtle
Stir a few crushed Lemon Myrtle leaves into a classic beurre blanc to finish delicate white fish or shellfish dishes. The herb’s brightness lifts the dish without overwhelming the other components.
Sweet treats and desserts
Use Lemon Myrtle in dessert recipes that call for citrus but aim for a milder, more refined note. A lemon myrtle syrup on panna cotta or a lemon myrtle-infused curd can bring complexity without bitterness. Balance sweetness with a pinch of salt and a splash of vanilla for depth.
Lemon Myrtle Essential Oil: A Potent Aroma with Broad Applications
The essential oil extracted from Lemon Myrtle is highly valued for its potent citrus character and antimicrobial properties. It is considerably stronger than the leaves themselves, so it is essential to use it sparingly and always diluted when applied to the skin or used in recipes that may rely on a lighter touch.
Uses of Lemon Myrtle essential oil
- In aromatherapy, for uplifting and refreshing scents
- In cosmetics and skincare, as a fragrant additive in soaps, creams, and lotions (always diluted)
- In cooking and confectionery, when a tiny amount is infused into syrups or drinks
Safety and dilution tips
Lemon Myrtle essential oil is highly concentrated. Do not apply undiluted to the skin; dilute in a carrier oil or water-based medium. If using in food, ensure the oil is food-grade and use only a few drops at most per dish. If you are pregnant, nursing, or have a medical condition, consult a healthcare professional before using essential oils in any form.
Health Benefits and Scientific Perspectives
Research on Lemon Myrtle highlights its antimicrobial and anti-inflammatory properties, largely attributed to its high citral and terpenoid content. These compounds contribute to its ability to inhibit certain bacteria and fungi and may offer soothing effects for minor irritations when used topically in diluted form. While Lemon Myrtle is celebrated for its clean flavour and potential health benefits, it is not a substitute for medical treatment. Consumers should use Lemon Myrtle as a flavouring or fragrance, and discuss any health concerns with a medical professional if needed.
What the science suggests about Lemon Myrtle
Studies on Backhousia citriodora indicate antimicrobial activity against a range of microbes, with particular strength in essential oil extracts. The consensus in the scientific community emphasises the importance of concentration and preparation method; culinary use tends to be much safer and more controlled than concentrated essential oil applications in non-food contexts. For those using Lemon Myrtle as a dietary supplement, it is sensible to source high-quality, food-grade products and to follow manufacturer guidelines.
Cultivation and Growing Lemon Myrtle
Growing Lemon Myrtle can be a rewarding project for home gardeners and urban growers alike. The plant prefers warm, humid conditions and rich, well-drained soil with regular moisture. In cooler climates, it benefits from sheltered positions and protection from frost. For container growing, choose a large pot with good drainage and use a potting mix that includes organic compost and perlite to ensure aeration and drainage.
Site selection and soil
- Sunlight: full sun to partial shade
- Soil: well-drained, slightly acidic to neutral
- Water: consistent moisture but avoid waterlogging
Maintenance and harvesting tips
Prune Lemon Myrtle lightly after harvest to maintain a compact shape and promote new growth. Leaves can be harvested as needed; for the most intense aroma, pluck leaves in the morning when the essential oils are at their peak. If growing indoors, provide adequate humidity and regular feeding with a balanced fertiliser during the growing season.
Buying, Storing and Selecting Lemon Myrtle
When purchasing Lemon Myrtle, consumers should decide whether they want fresh leaves, dried leaves, or essential oil. Fresh leaves are ideal for immediate cooking and garnishes, dried leaves are great for pantries and slow cooking, and essential oil is best for small-batch creations or fragrance uses. Storage matters: keep fresh leaves in the refrigerator, wrapped to retain moisture; dried leaves in an airtight container away from light; essential oil in a dark bottle in a cool place, away from heat and sunlight.
Quality indicators
- Fresh leaves: vibrant colour, strong citrus aroma, no signs of browning
- Dried leaves: should be fragrant and not overly crushed or damp
- Essential oil: pure, with no added solvents or diluents; check the label for concentration and recommended uses
Recipes and Inspiring Ideas with Lemon Myrtle
Here are some tested ideas to help you integrate Lemon Myrtle more fully into meals and daily routines.
Fresh herb pesto with Lemon Myrtle
Combine fresh Lemon Myrtle leaves with basil, garlic, pine nuts, parmesan, and olive oil for a vibrant pesto that complements seafood, grilled vegetables, or flatbreads.
Lemon Myrtle-infused vinaigrette
Whisk lemon juice, olive oil, Dijon mustard, salt, and a pinch of finely chopped Lemon Myrtle leaves for a refreshing dressing that brightens salads and grain bowls.
Non-alcoholic and alcoholic beverages
For a refreshing mocktail, steep Lemon Myrtle leaves in hot water, chill, and combine with sparkling water, cucumber ribbons, and a hint of honey. For an adult version, add a splash of gin or vodka and a few ice-cold mint sprigs.
If you don’t have Lemon Myrtle on hand, you can approximate its brightness with a combination of lemon zest or lemon verbena and a touch of lime leaf. However, these substitutes will not replicate the exact aroma and gentle sweetness of Lemon Myrtle, so use them as a last resort when a recipe relies on the unique character of this herb.
Allergies, Safety and Responsible Use
As with any herb or essential oil, some individuals may have sensitivities or allergies. If you are pregnant, nursing, or have a medical condition, consult a professional before using Lemon Myrtle essential oil or introducing large amounts of the herb into your diet. Always ensure that any essential oil used for topical application is adequately diluted and that the product is food-grade if intended for culinary use.
