Sesbania punicea is widely used as an ornamental plant for its attractive compound leaves, bright red flowers and persistent winged fruit. As with many invasive ornamentals, rattlebox has found its way out of cultivation and into natural areas. It favors moist, wet environments and is often found along river banks and wetlands. Sesbania punicea is native to South America. All parts of Sesbania are poisonous, particularly the seeds.
