Maclura tinctoria, known as old fustic and dyer's mulberry,[3] 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.[4] It is dioecious, so both male and female plants are needed to set seed.[5]
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:[3]
