Chilean Rimu is a species of coniferous tree found mainly in southern Chile and Argentina. It is also known by several other names depending on the region and language. In Spanish, it is called Araucaria araucana or Pehuen, while the Mapuche people call it Pewen or Piñón. In English, it is also known as Monkey Puzzle Tree or Chile Pine. The tree is commonly used for ornamental purposes in gardens and parks as its unique pattern of spiky branches makes it a popular choice. Its edible nuts, known as piñones, are also enjoyed as a traditional food in the Chilean and Argentinian regions where it grows.
