Samanea saman
Rain Tree
The Samanea saman, commonly known as the Rain Tree, is a large, fast-growing, and sprawling deciduous or semi-evergreen tree prized for its wide, umbrella-shaped canopy and ability to provide excellent shade. Native to Central and South America, it can grow up to 25 to 30 metres tall with a canopy spreading up to 40 metres in diameter. The tree produces small, pink and white powder-puff-like flowers and long, dark brown seed pods that are often consumed by livestock.
This drought-tolerant and hardy tree is widely planted in tropical and subtropical regions as an ornamental or shade tree for parks, streets, and large gardens.
