Gymnocladus dioicus L. (Kentucky Coffeetree)
Gymnocladus dioicus L. (Kentucky coffeetree, or coffeenut) is a member of the Leguminosae family. As a native North American species, the tree is completely unrelated to the tropical coffee plant (Coffea arabica, family Rubiacea); however, its common name was acquired because early North American settlers once used its rich brown, bitter seeds as a coffee substitute (Sargent 1965). The heavy, durable lumber from Kentucky coffeetree has limited economic value, but has been used in rough construction (fencing and rails) and also in cabinet construction (Carter 1977).
