Senna spectabilis

Senna spectabilis is a plant species of the legume family (Fabaceae) in the subfamily Caesalpinioideae native to South and Central America. They are often grown as an ornamental in front yards, parks, gardens, buildings etc. due to their bright yellow flowers that bloom during the summer months. They are also known as golden wonder tree, American cassia, popcorn tree, Cassia excelsa, golden shower tree or Archibald's cassia. The plant has become an invasive alien species in parts of Africa such as Kenya, Malawi, Tanzania and Uganda, and also in South-India, after it was introduced for resources such as firewood as well as to help combat deteriorating ecosystems affected by deforestation and desertification. Currently, S. spectabilis is overtaking native tree species of forestry ecosystems around the world because of its ability to grow quickly. ...read more on Wikipedia.
