Reseda luteola

Reseda luteola is a plant species in the genus Reseda. Common names include dyer's rocket, dyer's weed, weld, woold, and yellow weed.[1] A native of Eurasia, the plant can 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.[2] The yellow could be mixed with the blue from woad (Isatis tinctoria) to produce greens such as Lincoln green.[2] The dye was in use by the first millennium BC, and perhaps earlier than either woad or madder. Use of this dye came to an end at the beginning of the twentieth century, when cheaper synthetic yellow dyes came into use.[3] France exported large quantities of weld.[1]

It prefers waste places. Good weld for dye must have flowers of a beautiful yellow or greenish color, and abound in leaves; that which is small, thin-stemmed, and yellow is better than that which is large, thick-stemmed, and green; that which grows on dry, sandy soils is better than that produced on rich and moist soils. For the greatest production of coloring matter, the plant should be cut before the fruits show much development, otherwise the pigment diminishes. Dye from weld serves equally for linen, wool, and silk, dyeing with proper management all shades of yellow, and producing a bright and beautiful color.[1]
