The Norfolk Island Pine (Araucaria heterophylla) is a stunning evergreen tree native to Norfolk Island, a small island in the Pacific Ocean between Australia, New Zealand, and New Caledonia. While its name suggests it may be a pine, the Norfolk Island Pine is actually a member of the Araucariaceae family and is more closely related to other ancient conifer trees, such as the hoop pine and the bunya pine.
Known for its symmetrical, pyramidal shape and elegant appearance, the Norfolk Island Pine is highly valued in landscaping and as a houseplant in many parts of the world. But beyond its beauty, the tree has numerous practical uses and products that have made it significant in various industries. Let’s dive into the uses and products derived from this versatile tree.
