The Reseda Luteola, or weld plant.
Weld (Reseda Luteola) is a native Eurasian plant of the genus Reseda, commonly known as dyer’s rocket, dyer’s weed or yellow weed. It is also the name of a yellow dye produced by the leaves of the plant. It is rich in luteolin, a flavonoid that produces a bright yellow dye.
Weld has been used for hundreds of years in Scandinavia, Europe and the Middle East as a source of yellow, often being mixed with woad (Isatis tinctoria) for green and madder (Rubia tinctorum) for orange.
