Senna didymobotrya is a species of flowering plant in the legume family known by the common names African senna, popcorn senna, candelabra tree, and peanut butter cassia. It is native to Africa, where it can be found across the continent in several types of habitat. It has been introduced to many other parts of the world for use as an ornamental plant, a cover crop and a leguminous green manure. In some places it is now naturalized in the wild, for example, in parts of Indonesia, Australia, Mexico, and the United States in California, Florida, and Hawaii.
