  • It can grow to approximately 12 feet (3.7 m) in height. 

  • While native to Peru, it has been introduced in many other countries for its attractive simple yellow flowers, it is now a common weed in swampy areas around the world

  • The weed has spread rapidly on a large scale.

  • It was most likely introduced as an ornamental plant because of its tiny yellow flowers.

  • The rapid spread of the weed has disrupted the balance of perennial foraging grounds.

  • The growth of grass and native plants that elephants and other animals, including gaur, prefer to eat is limited due to the presence of this weed.
