The 'Rain Tree' is widely cultivated as an ornamental and together with the 'Flamboyant' (Delonix regia Raf.) belongs to the most common street trees; both are characterized by a broad umbrella-shaped crown. A good honey plant. Pods used as fodder for cattle, pigs and goats. The wood is used for furniture, general construction, boxes, crates etc., but is not durable.
During the night, and when the sky is overcast during the day, the leaves are hanging loosely down as in most other Mimosoids, hence its popular name Rain Tree. Another explanation for the name is the excretion of sugar-rich juice by extrafloral nectaries, which drops from the trees like rain.
