Senna sulfurea, known as sulfur senna, is a shrub or small tree in the legume family native to tropical Asia and the Pacific, now widely naturalized in tropical regions worldwide. It produces bright sulfur-yellow flowers in large terminal panicles and long cylindrical seed pods, making it conspicuous in disturbed habitats and roadsides. The plant is commonly used in traditional medicine and as an ornamental, and has become invasive in parts of Australia and the Caribbean.
