Leucaena: K-6 Peruvian
(Leucaena diversifolia, L. leucocephala, L. pallida X L. leucocephala)

The genus Leucaena includes several multipurpose tree species and interspecific hybrids that can withstand almost any type or frequency of pruning or coppicing. They are native to Mexico and Central America, and now abundant in the Philippines, West Africa, Nepal, Australia and Hawaii. Spanish sailing vessels reportedly introduced Leucaena to Asia four centuries ago. A total of thirteen species of Leucaena, mostly shrub species, are distributed within the New World tropics and subtropics.

A variety of L. leucocephala from Peru that exhibits excessive branching and therefore more foliage. This variety will grow very tall unless pruned or coppiced and is usually used for forage.
