Heart
Sweet, hay-like, vanillic green. Woodruff smells like dried sweet grass soaked in coumarin: the scent of May wine and freshly mown lawns with tonka-bean sweetness.
Sweet, green, coumarin-rich. Fresher than tonka, greener than vanilla, more herbal than hay. If tonka is the dessert version of coumarin, woodruff is the garden version.

The Full Story
Woodruff (Galium odoratum) is a shade-loving European herb whose scent develops upon drying. The fresh plant is nearly odorless, but enzymatic hydrolysis releases coumarin from bound glycosides as it wilts.
The dried herb smells strongly of coumarin with supporting green-herbaceous and faintly vanillic qualities. It is the traditional flavoring for German Maibowle (May wine).
In perfumery, woodruff functions as a natural coumarin source, bridging green-herbaceous and sweet-vanillic families.
Germany limits coumarin in food above 2 mg/kg due to hepatotoxicity concerns. Traditional Maibowle recipes specify strict limits on woodruff steeping time to keep coumarin within legal bounds.
Extraction & Chemistry
