Narra Tree Facts

In Asia, most countries have an indigenous reddish hardwood called Narra (Pterocarpus indicus).

As a result of its numerous uses, the Narra was declared by the governor-general as the national tree of the Philippines.

Narra Trees are large, reaching heights of 33 meters, and have trunks with a diameter of two meters. The trunks at the base are typically seven meters in diameter and fluted. The Narra branches are long at first, then arch over and eventually droop at the ends.
