Maclura tinctoria, formerly morus tinctoria[1] and 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.[citation needed] This dye contains the flavonoid morin.

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
