General Information

Weld is a weedy plant that was used in the past as a source for a brilliant yellow dye. It was originally from the Middle East, North Africa, and the Mediterranean area, but has subsequently spread throughout Europe.

Medicinal Uses: Narcotic (mild). In medicine it has been employed as a diaphoretic and diuretic, but it is now used only for dyeing purposes

Other Notes: It is called Base Rocket because its leaves are like a rocket, and from being used as a base in dyeing wool. It was used as a yellow and green dye to color wool and cotton. Dutch pink is also manufactured from it. The dye has also been applied to silk, and for paper, mohair, and linen. Blue cloth is dipped in it to dye it a green color. When the plant is in flower it is plucked up, and used in the fresh and the dried state.

When the dye of Weld is combined with the blue dye of Isatis tinctoria (Woad), the result is a brilliant green dye.

The famous medieval colors, Saxon green and Lincoln green, were produced by over-dying weld yellow with woad blue. If you are interested in reproducing these colors today, it is very easy to do using indigo. Anyone interested in producing authentic colors for living history pageants will want to give this a try.
