Its a deciduous tree and introduced from Mexico. As it belongs to Pea family, is used for nitrogen fixation and improving quality of soil. It can attain a height up-to 10 m. Tree shades it leaves during February / March. Flowers are bright, pinkish in color and are present in bunch. Ants are often seen feeding on them Its also food plant for many butterflies, specially from the "Blue" category. Its host plant for Pea Blue, common cerulean. During ore-monsoon season, hundreds are Pea-blues are seen near this trees. I am not sure if this tree is also called as उन्दरी in Marathi, as bark is used as rat poison.
