The Norfolk Island pine (Araucaria heterophylla) is a distinctive evergreen conifer native to Norfolk Island, a small territory in the South Pacific Ocean. Despite its common name and appearance, it is not a true pine; it belongs to the ancient family Araucariaceae and is closely related to the monkey-puzzle tree. Globally celebrated for its perfectly symmetrical, tiered branches, this plant functions as a stately outdoor tree in warm coastal zones and a highly popular "living Christmas tree" houseplant indoors.
