Tart-green, thin, and faintly floral. The oxalic acid character dominates — a sour, almost citric green that is more taste than smell. The flower contributes a delicate, barely perceptible sweetness. Less strong than violet leaf, less sweet than violet flower, with an acidic sharpness unique to the Oxalis genus.

The Full Story
Violet woodsorrel (Oxalis violacea) is a small perennial with violet-pink flowers, unrelated to true violets despite its name. It belongs to the Oxalidaceae (wood-sorrel family), a group of plants characterized by oxalic acid content that gives them a distinctly tart, sour taste.
The scent of Oxalis flowers is minimal — a faint, thin floral quality with a green-acidic character from the oxalic acid. The leaves and stems have a more pronounced sour-green smell when crushed. The overall olfactory impression is tart, vegetal, and understated — a wildflower that whispers rather than projects.
There is no commercial Oxalis essential oil or absolute. The note is a conceptual reference in perfumery, evoking woodland floors, acidic green freshness, and delicate wildflowers. It is reconstructed using sour-green materials and faint floral accords.
All Oxalis species contain oxalic acid, which gives them their sour taste and their name (from the Greek 'oxys,' sharp/acidic). In high doses, oxalic acid is toxic — it binds calcium in the blood and can cause kidney stones. The small amounts in wood-sorrel are harmless and have been used in folk medicine and as a salad green.
Extraction & Chemistry
Extraction method: No commercial essential oil or absolute exists. The plant produces insufficient volatile compounds for extraction. The note is always reconstructed from sour-green synthetics and faint floral materials.

In Perfumery
Violet woodsorrel is a conceptual note with no commercial extract. Perfumers approximate it using sour-green materials (rhubarb, green-tart synthetics), faint violet-type florals, and acidic modifiers. It provides a woodland-floor freshness — tart, green, and understated. Used in green, forest, and wildflower compositions as a subtle acidic-green accent.
