This tree is native to central and northern South America. It has been introduced in Africa as an ornamental. Cassia spectabilis is tolerant of cool conditions (15-25 C) and therefore suitable for elevations up to 2,000 m. It grows well with a mean annual rainfall of 800-1,000 mm in deep, moist, sandy or loamy soils. It can be evergreen in climates with rain all year round, but can become deciduous in areas with dry seasons. In Uganda it is widely cultivated as a boundary marker and in woodlots, especially in Central and Western Regions. In Kampala, Cassia can be found along Archer road, Haji Musa Kasule road, within Uganda Golf course club, Makerere University among other places.

Fast growing on good sites and slow in dry sites; coppicing, pruning to develop strong structure.
