Reseda odorata is known primarily as cultivated plants, probably of artificial hybrid origin (S. Martín-Bravo et al. 2007). Probably originating in the southeastern Mediterranean basin (M. S. Abdallah and H. C. D. de Wit 1978), it has been grown in gardens for centuries for its fragrant flowers. The perfume industry has used the essence of the flowers. Now subcosmopolitan, R. odorata escapes from cultivation occasionally but is rarely found naturalized. It is far less common in the flora area than the other species of the genus.
