The opening is fresh and lightly citrusy with a clean green quality that gives way quickly to the full floral heart: lily of the valley and orange blossom at the centre, with muguet and neroli nuances running alongside, and a faint sweet, aromatic quality that keeps the whole profile from reading as sharp or strident. It is lighter and fresher in feel than many narcotic white florals, with a transparency and diffusiveness that makes it easy to work with across delicate flower types. The tenacity is the other defining quality: at 64.3 hours on a smelling strip, it outlasts many heavier-seeming materials and anchors a floral composition without adding weight.

Verdantiol works as a fresh floral heart note, white floral modifier, and fixative across fine fragrance and personal care.
