Diagnostics:

Gliricidia sepium is a cultivated tree sparingly planted along our roads and parks. The natural form has voluminous and straggling foliage while cultivated ones here normally have their lower branches pruned, resulting in a dense cluster of upward pointing branches. The pinnate leaves are arranged spirally, giving a bushy appearance. Each leaflet is elliptic with pointed tips and a pale green underside. The inflorescences are pink.


Interesting Facts:

The Mexican Lilac was first brought to Philippines by the Spanish in the early 1600s and subsequently to Sri Lanka in the 18th century; and from there to other parts of Asia (World Agroforestry Centre). It used to be a common roadside tree in Singapore, but its popularity has since waned (NParks, 2009).
