Wallflower (Erysimum cheiri, syn. Cheiranthus cheiri) belongs to the Brassicaceae — the cabbage family. That botanical kinship makes its intense fragrance an oddity: most crucifers smell vegetal or sulphurous, not honeyed-spicy. The flower's scent profile, analysed by GC-MS, reveals thymol (28%) and carvacrol (22%) as dominant volatiles, with dodecane providing a faint waxy backdrop. Static headspace analysis of the living flower detects dimethyl trisulfide as the single largest volatile component — a sulphur compound absent from the dried extract, responsible for the green-sulphurous edge noticeable only when smelling the bloom on the plant.

The olfactory impression is warm, phenolic, and spiced rather than conventionally floral. Thymol lends a thyme-oregano bite; carvacrol reinforces it with a drier, more medicinal quality. The effect is closer to a spice poultice than a bouquet. Underneath, traces of benzyl benzoate and nerolidol contribute a faint balsamic sweetness in the dry-down. The scent is often compared to carnation, but wallflower is drier, more herbal, less powdery.

True wallflower absolute is commercially rare. The flower yields very little extractable material — estimated at 0.01–0.06% by steam distillation — making large-scale production uneconomical. In practice, perfumers reconstruct the note using isoeugenol, benzyl salicylate, thymol, and honey accords. The reconstruction leans heavier on the spicy-sweet axis, omitting the sulphurous living-flower character that only headspace capture reveals.
