Lily of the Valley in Perfume: The Silent Flower

Lily of the valley smells fresh, green and dewy, with a clean, slightly lemony sweetness and a soft, almost soapy radiance — a spring morning in a shady garden. In French it is muguet. It is one of the so-called silent flowers: its scent cannot be usefully extracted, so every lily of the valley perfume is a reconstruction built from aroma molecules and other materials. Some of the molecules once central to that reconstruction have recently been banned in the European Union, so modern muguet perfumes are built differently from older ones.

A flower with no extract

Lily of the valley, Convallaria majalis, is a small woodland plant of Europe and Asia, with arching stems of white bell-shaped flowers and a remarkably strong scent for its size. But distillation and solvent extraction give no useful perfume material from it. The same is true of several other fragrant flowers, which perfumers call "silent" or "mute" flowers; see Are Perfume Notes Real Ingredients?.

How perfumers rebuild it

For most of the twentieth century, muguet accords relied on a group of synthetic molecules with fresh, watery-floral, lily-like smells. Two of the best known were later restricted or banned in the European Union:

HICC (sold as Lyral) — cosmetic products containing it could no longer be placed on the EU market from 23 August 2019, nor made available from 23 August 2021, because it was among the fragrance allergens causing the most contact allergies.
Butylphenyl methylpropional (sold as Lilial) — banned in EU cosmetics from 1 March 2022, after being classified as toxic to reproduction.

Perfumers now build muguet from other molecules, often with green notes, rose and citrus. Some find the newer accords lighter or different; others find them just as convincing. This kind of change is one reason perfumes are reformulated; see Why Perfumes Are Reformulated.

What lily of the valley smells like, facet by facet

Green and dewy — fresh leaves and morning damp.
Clean and soapy — a bright, laundered radiance. See What Does "Clean" Mean in Perfume?.
Lemony and fresh — a citrus-like lift.
Soft and floral — a delicate sweetness, with a hint of rose and lilac.

Lily of the valley is the purest proof that a perfume note is an idea, not an ingredient.

How perfumers use it

As a soliflore — a fresh, spring-like perfume built around muguet.
In fresh florals, as a bright, airy heart. See Floral Fragrances.
In clean and soapy perfumes, where its laundered radiance is central.
As a supporting note, to freshen roses and white flowers. See Rose in Perfume.
In chypres, where a classic floral heart often included muguet. See What Is a Chypre Perfume?.

Lily of the valley in culture

In France, sprigs of muguet are traditionally given on 1 May as a token of good luck and spring, and sold on street corners. Its delicate, hopeful character — and its traditional place in bridal bouquets — makes it popular for occasions. See How to Choose a Wedding Perfume.

Wearing lily of the valley

It suits daytime, spring and the office — fresh, gentle and easy to share. See How to Choose a Perfume for the Office.
If you loved an older muguet perfume that now smells different, regulation may be part of the reason. See Why Does My Perfume Smell Different Now?.
Test the whole day. Muguet accords are often bright at first and soften to musk and woods.

Common questions

Is lily of the valley perfume made from the flower?

No. The flower gives no usable extract; the note is always recreated.

Why was Lilial banned?

The EU classified it as toxic to reproduction, and substances with that classification are prohibited in cosmetics. It has been banned in EU cosmetics since March 2022.

What is muguet?

The French name for lily of the valley, commonly used in perfumery.

Is lily of the valley the same as a lily?

No. Despite the name, it is a different plant from true lilies, and smells quite different — fresher and greener.
