Lemongrass essential oil smells clean, green and bold: lemony like citrus peel, but grassier and sharper than any fruit. If you are new to it, this guide covers what to expect from the scent, where it sits in a blend and how makers use it.
Quick answer: Lemongrass essential oil is steam-distilled from the leaves of Cymbopogon grasses and is rich in citral, the compound behind its strong lemon character. It smells bright, lemony and grassy with a faintly earthy, tea-like undertone. Lemongrass is usually classed as a top-to-middle note: it opens with a sharp citrus burst but lasts longer than lemon or lime. It blends well with lavender, basil, ginger, cedarwood and lime, and a small amount goes a long way.
What does lemongrass essential oil smell like?
The first sniff is pure lemon-drop brightness, then a grassy, freshly cut stalk note takes over. Underneath sits a soft, slightly earthy warmth that keeps it from reading as purely citrus. Compared with lemon peel, lemongrass is more herbal and longer lasting; compared with citronella, it is cleaner and sweeter.
- Opening: sharp, lemony and sparkling
- Heart: green, grassy and freshly cut
- Drydown: soft, earthy and lightly herbal
Is lemongrass a top note?
Lemongrass is generally listed as a top note, though many perfumers place it on the border between top and middle. Its citral-rich opening evaporates quickly like other citrus scents, but the grassy heart hangs on noticeably longer than lemon, lime or orange. That staying power makes it a useful bridge, carrying a bright opening into the middle of a blend.

How makers use lemongrass
Lemongrass is a favorite in cold-process soap and candles because its scent is strong enough to come through a finished bar or a lit wick. It is also popular in room sprays and diffuser blends whenever a fresh, clean-smelling note is wanted. Try these pairings:
- Lemongrass with lavender for a softer herbal-floral take
- Lemongrass with basil for a green, kitchen-garden blend
- Lemongrass with ginger for warm, spicy brightness
- Lemongrass with cedarwood for a fresh, woody finish
Soap and candle makers should follow their soap base or wax supplier's recommended fragrance load, because lemongrass can easily take over a batch. You will find more ideas in our post on herbal soap scents.
In a diffuser, two drops of lemongrass with three of lavender make an easy, balanced starting point. In a linen or room spray, pair it with lime for a crisp, spa-like scent that still feels warm, or with a drop of ginger for something brighter and spicier. Because the grassy heart lingers, lemongrass also holds up better than lemon in candles, where fleeting citrus notes often disappear once the wax is lit.
Choosing a lemongrass oil
Look for an oil labeled with its botanical name, steam distillation and country of origin. Good lemongrass is pale yellow to amber and smells lively rather than flat. Store it cool, dark and tightly capped; over time it can turn darker and more viscous and lose its sparkle.
