It is a naturalized species in the eastern United States and in the Pacific states. It is also occasionally planted in southern England. In India, the species is found in the plains and the Himalayas, up to an elevation of 11000 feet (3355 m). The tree is drought resistant, and has become adapted to dry, warm areas.

Shrinkage, Tangential = fairly large Shrinkage, Radial = small Shearing strength (parallel to grain) = very high Modulus of Elasticity (stiffness) = very low Max. crushing strength = medium Hardness (side grain) = hard Bending strength (MOR) = low Toughness-Hammer drop (Impact Strength) = high Shearing strength (parallel to grain) = very low Modulus of Elasticity (stiffness) = low Max. crushing strength = low Max. crushing strength = high Hardness (side grain) = medium Compression strength (parallel to grain) = high Bending strength (MOR) = medium The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Strength in compression parallel to grain is in the high range. Other species in this range include Teak, White oak, and Hard maple. Hardness is rated as medium. It resists denting and marring about as well as white oak or birch. The weight is high. The density is high.
