Distribution and habitat

Leucaena leucocephala is native to southern Mexico and northern Central America, but is now found in many tropical and subtropical regions worldwide. It is often found in disturbed areas, along roadsides, and in abandoned fields. It prefers well-drained soils and can tolerate a wide range of soil types.

Uses
