What does geranium smell like? The rosy, minty leaf behind classic colognes

Rub a leaf of a scented geranium between your fingers and your hand will smell of roses, mint and lemon. That leaf is one of perfumery's great workhorses. It is in classic barbershop colognes, rose perfumes, soaps and modern fresh scents for all genders. Geranium rarely takes the spotlight, but once you learn its smell you will find it everywhere.

What does it smell like?

Rosy and green, with a fresh, slightly sharp edge. A good geranium oil can show:

• Rose: a clear rose smell, but greener and less sweet than rose petals
• Mint: a cool, herbal freshness
• Lemon: a bright, citrusy lift
• Green leaves: crushed stems and foliage
• A metallic or peppery edge: a dry, slightly spicy tang in some oils

Geranium sits between flowers and herbs. That makes it a natural link between floral notes like rose and fresh notes like lavender, citrus and mint.

Where it comes from

Here is a surprise. The "geranium" used in perfume is not a true geranium. It comes from pelargoniums, close relatives that many people also call geraniums. The main perfume plants are rose-scented types, often sold as Pelargonium graveolens or rose geranium. Most are hybrids developed in cultivation.

Wild pelargoniums come mainly from South Africa. The rose-scented hybrids used today were developed in Europe from plants brought from there.

In perfume, the scent is in the leaves, not the flowers. Tiny glands on the leaves and stems hold the fragrant oil.

The main producing regions today are:

• China: now the biggest producer by volume
• Egypt: a major source of good-quality oil
• Morocco: another established producer
• Réunion: an island in the Indian Ocean once called Bourbon. "Geranium Bourbon" oil from here is still treated as the quality benchmark, though production is small.

India, Madagascar and other countries also grow it.

How it's made

1. Harvest. The leafy stems are cut, usually several times a year.
2. Distillation. The plant material is steam- or water-distilled. The oil rises with the steam and is collected.
3. Optional extras. Some producers also make a geranium absolute using solvents, which smells richer and more rounded.

The oil's main molecules include citronellol and geraniol, two classic rose molecules. In fact, geraniol was named after geranium. Isomenthone adds the minty touch, and rose oxide adds a sharp, green, metallic rose note. Oils from different regions have slightly different balances. Bourbon oil is often described as rounder and richer, while Chinese oil tends to be more lemony and sharp.

Perfumers also use rhodinol, a rosy material traditionally made from geranium oil.

A short history of geranium

• South Africa: Pelargoniums grew wild there long before they were brought to Europe.
• Europe, 17th–18th centuries: Plant collectors brought pelargoniums to European gardens, where they became popular houseplants and were bred into many scented varieties.
• Grasse, 19th century: Commercial growing for perfume began in the early 19th century around Grasse, the French perfume capital. It continued there until around the Second World War.
• North Africa and Réunion: Growers spread production to Algeria, Morocco and Réunion. Réunion's "Bourbon" oil built a strong reputation.
• Today: China and Egypt now produce most of the world's geranium oil.

Geranium in modern perfume

Geranium has two big jobs:

1. In men's and unisex fragrances. It is a key part of many fougères, a family of fresh, herbal, barbershop-style scents usually built on lavender, coumarin (a hay-like note) and oakmoss. Geranium adds a rosy, minty freshness that ties these notes together.
2. In rose perfumes. Because it shares many molecules with rose, geranium can support or stretch a rose accord. It makes rose greener, brighter and more modern, and it costs far less than rose oil.

It also appears in fresh colognes, green florals and many soaps and cosmetics.

Real vs synthetic geranium

Natural geranium oil is widely available and relatively affordable, so it is commonly used as-is. Perfumers also use its individual molecules, like citronellol and geraniol, to build rosy effects. Some people with sensitive skin react to geraniol and citronellol, which is why you will see them listed among the allergens on EU perfume labels.

What geranium pairs well with

• Lavender: the core of the classic fougère.
• Rose: a natural partner that shares many of the same molecules.
• Mint and herbs: basil, sage and rosemary bring out its green side.
• Citrus: bergamot and lemon add sparkle.
• Spices: clove and pepper make it warmer and drier.
• Woods and moss: vetiver, cedar and oakmoss give depth.

Perfumes to try

• Géranium pour Monsieur by Frédéric Malle: a crisp, minty geranium with a clean, spicy finish. The modern reference.
• Geranium Odorata by Diptyque: fresh, green and peppery.
• English Fern by Penhaligon's: a classic fougère with geranium and lavender.
• Replica At the Barber's by Maison Margiela: a modern barbershop scent with geranium, lavender and herbs.

How to wear geranium

• It works all year, but feels especially good in spring and on fresh, cool days.
• It is ideal for the office. Most geranium scents are clean and polished rather than loud.
• If you think you dislike florals, try geranium. Its herbal side makes it feel fresh rather than flowery.
• Layer a geranium scent with a simple rose or lavender for an easy twist.

Who will love it

Fans of fresh, green and herbal scents. People who like classic barbershop colognes, and rose lovers who want a greener, more modern take. Anyone who prefers something clean and versatile will find geranium a reliable friend.
