Leucaena leucocephala is widely grown as an agroforestry species in tropical regions. In the 1970s and 1980s the tree was very widely planted as a forage tree legume and seen as a solution to many tropical agriculture problems as it was fast growing, nitrogen fixing, fairly drought tolerent and could be used for fodder, shading other crops and as firewood. Its value was recognised by the Spanish colonists of the Americas who spread seeds fo the plant around the tropics. However the species soon became a weed and is now causing many problems by displacing native flora
This mimosoid legume is native to Central America and shows typical features of this group of Fabaceae including the twice pinnate leaves and the ball shaped flower heads. The pods are typical pea-like legumes.

Uses
Leadtree is valued as an excellent protein source for cattle fodder, consumed browsed or harvested, mature or immature, green or dry. The nutritive value is equal to or superior to alfalfa. Leadtree has gained a favorable reputation in land reclamation, erosion control, water conservation, reforestation and soil improvement programs, and is a good cover and green manure crop. The leaves, used as a mulch around other crops, are said to significantly increase their yields. It is said to possess the power of extracting selenium from the soil and concentrating selenium in the seed. This could be used to ameliorate seleniferous soils if the feed were discarded or used for some purpose other than feed. Seeds yield about 25 percent gum worthy of commercial investigation. Seeds after softening are strung as beans into various items of jewelry for tourists in Puerto Rico and the Virgin Islands.
