Maclura tinctoria, commonly known as Old Fustic or Dyer's mulberry[2] is a medium to large tree of the Neotropics, from Mexico to Argentina. It produces a yellow dye called fustic primarily known for coloring khaki fabric for U.S. military apparel during World War I. This dye contains the flavonoid morin.[3]
The leaves can be used to feed silk worms.[4]
Old fustic is not to be confused with Young Fustic (Rhus cotinus) from southern Europe and Asia, which provides a more fugitive colour.
Dyeing
Fustic is a bright yellow dye that is very color-fast when used with mordants. It is frequently combined with other dyestuffs and various mordants to produce a range of yellow and greenish colors:[2]
- With woad or indigo: bright or Saxon greens
- With bichromate of potash: old gold
- With logwood and bichromate of potash: greenish yellows
- With copper sulfate: olive greens
- With ferrous sulfate: dark greens
