|discussion=<p><i>Reseda luteola</i> is a traditional Old World dye plant, used since Roman times. It contains a high amount of the flavonoid luteolin, which yields one of the most brilliant yellow dyes. When combined with woad (<i>Isatis tinctoria</i>, <i>Brassicaceae</i>), it yields “Saxon Green.” In the nineteenth century <i>R. luteola</i> was widely growing, which favored its spreading through many parts of the world; today, it has fallen into disuse. Its potential as a crop for natural dyeing of textiles is being re-evaluated. It is also grown as an ornamental; the appealing rosettes of yellowish green leaves acquire a reddish blush in cool weather.</p>
