Lemon Myrtle Benefits & Uses

Lemon myrtle has long been valued in Australia for its vivid lemon aroma and useful leaves. In modern herbal and home-fragrance use, it is most often chosen when a clean, bright, citrus-like scent or flavor is wanted without using actual citrus peel.

• Herbal tea: dried or fresh leaves can be steeped for a fragrant lemony infusion.
• Culinary flavoring: the dried leaf is used in cakes, cookies, sauces, marinades, dressings and spice blends.
• Natural home fragrance: dried leaves work beautifully in potpourri, simmer pots, sachets and botanical bowls.
• Botanical crafts: the leaves add a distinct Australian bushland note to handmade gifts and dried herb blends.
• Aromatic blending: lemon myrtle essential oil is used in very small amounts for a strong lemon note in room blends and potpourri refresh oils.

Its main appeal is its unmistakable aroma: sharper and more leaf-like than sweet orange, stronger than lemon balm, and more distinctly herbal than lemon peel.

Lemon myrtle can be used fresh, dried, crushed, powdered or infused. The leaves are highly aromatic, so a small amount is often enough.

How to Use Lemon Myrtle Leaves

• Tea or infusion: steep 1 teaspoon dried crushed lemon myrtle leaf in 1 cup hot water for 5–10 minutes, then strain.
• Culinary seasoning: use a small pinch of finely dried leaf or powder in baked goods, sauces, dressings and spice rubs.
• Potpourri: combine dried lemon myrtle leaves with dried citrus peel, eucalyptus leaves, rosemary, wood chips and flowers.
• Simmer pots: add a few dried leaves to a pot of water with citrus slices, rosemary or eucalyptus and warm gently.
• Sachets: blend dried leaves with lavender, chamomile or dried citrus peel for cupboards or drawers.

Flavor and Aroma Pairings

Lemon myrtle pairs especially well with orange peel, lemon peel, ginger, honey, vanilla, chamomile, rosemary, eucalyptus, lavender, calendula and soft woody notes such as cedarwood or sandalwood.

Using Lemon Myrtle Essential Oil

Lemon myrtle essential oil is much stronger than the dried leaf. For potpourri and room fragrance, start with only a few drops and blend it with softer oils such as sweet orange, lavender, cedarwood or sandalwood so the scent does not become too sharp.

Lemon myrtle is a warm-climate tree that prefers bright light, good drainage and protection from hard frost. In the USA, it is best suited to warm coastal, subtropical or mild frost-free areas, and is often most practical as a container plant in cooler regions.

• USA growing zones: best outdoors in warm regions around USDA Zones 9b–11. In colder zones, grow it in a large pot and bring it indoors or into a protected space during freezing weather.
• Light: full sun to part shade. In very hot, dry areas, afternoon shade can help protect young plants.
• Soil: fertile, well-drained soil with consistent moisture. Avoid waterlogged soil.
• Water: water regularly while young. Established plants tolerate short dry periods better, but the best leaf growth comes from steady moisture.
• Size: in warm climates it can become a small to medium tree. In pots it can be pruned and kept as a large shrub.
• Harvesting: pick leaves as needed once the plant is established, taking only modest amounts at one time so the plant keeps growing strongly.
• Container care: use a large pot, quality potting mix, good drainage and regular pruning to maintain shape.

Because lemon myrtle is frost sensitive when young, USA gardeners outside warm zones should treat it like a patio citrus or bay tree: outdoors in warm months, protected during cold snaps, and moved under cover before hard frost.

Lemon myrtle leaf is commonly used as a culinary herb, but it has a strong flavor and aroma, so start with small amounts. People who are pregnant, nursing, taking medication or managing a health condition should seek professional guidance before using concentrated herbal preparations.

• Essential oil caution: lemon myrtle essential oil is rich in citral and can be irritating or sensitizing if used too strongly. Do not apply it undiluted to the skin.
• Skin use: this page focuses on the herb leaf and home-fragrance uses, not topical treatment. Use properly formulated recipes if applying essential oils to skin.
• Pets and children: keep essential oils, scented potpourri and dried botanical blends away from pets and young children.
• Home fragrance: do not place scented potpourri directly on polished wood, painted surfaces, fabric or plastic, as essential oils may stain or damage finishes.
• Food use: only use food-grade dried lemon myrtle from a trusted source for cooking or tea.

For decorative potpourri, simmer pots and sachets, label blends clearly and do not treat them as edible unless every ingredient is food grade and the recipe is intended for culinary use.
