The araucaria araucana tree is indigenous to Central and Southern Chile and grows in the Andean foothills. Called the pewen by the locals and the monkey puzzle tree by others, this evergreen is the country’s national tree. Although it is protected from harvesting, the seed-filled cones are often collected as food. The leaves are tough with sharp edges. This hardy member of the conifer genus can grow up to 150 feet and live beyond a thousand years.
