Bluebell smells like an English wood in April, when blue flowers carpet the ground and the air is still a little damp. Galbanum brings that raw green of a snapped stem, and lavender calms everything that needs calming.

Then rose and jasmine add a quiet sensuality, the kind that knows exactly what it wants. Light it in the bathroom, with the water a little too hot and your phone on silent. The small flame does the rest.
