Araucaria heterophylla
Family: Araucariaceae
Araucaria heterophylla (synonym A. excelsa) is a species of conifer.. It is sometimes called a star pine, Polynesian pine, triangle tree or living Christmas tree, monkey’s puzzle plant due to its symmetrical shape as a sapling.
Young trees are often grown as houseplants in areas where the winters are too cold for them to grow outside, and are sometimes used as Christmas trees. It will not survive in areas subject to prolonged cold. However, there are a few specimens growing outdoors in the subtropical gardens.. The tendency for potted saplings to develop a barren appearance can be helped by growing them in clumps. In northern climates they can be left outdoors during summer or placed under grow lights to promote fuller growth.
