Derris elliptica, commonly referred to as tuba root or Derris root, is a climbing, woody vine native to tropical rainforests in Southeast Asia and the southwest Pacific islands. It is a member of the legume family, Fabaceae, and is known for its compound leaves, pinnate with 5 to 15 leaflets, and its small, pink to purple flowers that bloom in dense clusters. The plant can reach lengths of up to 10 meters when supported. Derris elliptica is particularly noted for its roots, which contain rotenone, a potent biopesticide and piscicide. The roots are traditionally harvested and crushed to release the rotenone, which is then used in organic insecticides and for fishing practices.

In cultivation, Derris elliptica is not commonly found in gardens due to its toxicity and specialized habitat requirements. However, it is of interest for its potential use in organic pest control. It thrives in moist, well-drained soils and requires a tropical climate with partial to full shade. While it is not typically grown for ornamental purposes, its ability to form dense foliage can make it useful for creating shaded areas in tropical gardens. Care should be taken when handling this plant due to its toxic properties, and it is not recommended for areas accessible to children and pets.CC BY-SA 4.0
