Leucaena Leucocephala is a versatile tree that tends to be invasive if not managed properly. Leucaena uses an extensive taproot system that grows deep into the soil, transferring water and minerals to the surface. A small raised structure (gland) is usually present on the leaf stalk (petiole), or just below where the lowest pair of branchlets (pinnae) meet.
