It is a deciduous tree that grows to about 15-25 meters in height with a large canopy that spreads equally wide. The leaves are a soft, shiny burgundy in early summer and mature to a glossy, deep green as the season progresses. Small clusters of white, purple, and pink flowers blossom on their branches throughout the year, maturing into brown seed pods. The tree is well suited to intense heat and sunlight and its dense network of lateral roots and its thick, long taproot make it drought tolerant. The dense shade it provides slows the evaporation of surface water and its root structures promote nitrogen fixation, which moves nutrients from the air into the soil. Withstanding temperatures slightly below 0°C to 50°C and annual rainfall of 5–25 dm, the tree grows wild on sandy and rocky soils, including oolitic limestone, but will grow in most soil types, even with its roots in salt water.Known by many names (Indian Beech, Pongam, Honge, Ponge, and Karanj among other) it is a leguminous tree that's well-adapted to arid zones and has many traditional uses. It is often used for landscaping purposes as a windbreak or for shade due to the large canopy and showy fragrant flowers. The bark can be used to make twine or rope and it also yields a black gum that is used to treat wounds caused by poisonous fish. The flowers are used by gardeners as compost for plants requiring rich nutrients. Although all parts of the plant are toxic and will induce nausea and vomiting if eaten, the fruits and sprouts, along with the seeds, are used in many traditional remedies. Juices from the plant, as well as the oil, are antiseptic and resistant to pests. In addition the Pongam tree has the rare property of producing seeds of 25-35% lipid content. The seed oil is an important asset of this tree having been used as lamp oil, in soap making, and as a lubricant for thousands of years. This oil is rapidly gaining popularity as an important source of fuel for diesel engines.
