  • Origin and Worldwide Distribution: This species is native to Argentina, Bolivia, Chile, Ecuador and Peru, and has been imported to other countries as an ornamental plant. It has escaped into the wild, and become invasive in countries like Australia, South Africa and the United States of America.

  • Potential or Known Impacts: This species forms dense stands that can crowd out native species. This overcrowding can cause problems for many environments as the dense stands create fire hazards.
