Reseda luteola
Also called Dyer's rocket, Dyer's weed, Woold, Yellow weed, Dyer's Weld, Wild Mignonette, Dyer's Mignonette
Weld is a biennial dye plant in the mignonette family that forms a leafy rosette in year one and flowers tall in year two. It is grown for the yellow dye luteolin in its leaves and stems, and it self-seeds readily.
Reseda luteola is a flowering plant species in the family Resedaceae. Common names include dyer's rocket, dyer's weed, weld, woold, and yellow weed.
A native of Europe and Western Asia, the plant can also be found in North America as an introduced species and common weed. While other resedas were used for the purpose, this species was the most widely used source of the natural dye known as weld. The plant is rich in luteolin, a flavonoid which produces a bright yellow dye. The yellow could be mixed with the blue from woad (Isatis tinctoria) to produce greens such as Lincoln green.
