Monkey puzzle tree (Araucaria araucana) in a spread form is a prehistoric evergreen conifer characterized by thick horizontal branching, rigid geometric structure, and densely armored foliage. The trunk is upright and heavily textured, supporting broad, whorled branches that extend outward to form a layered, sculptural canopy. Each branch is covered in stiff, triangular, scale-like leaves that persist for many years, creating an almost reptilian surface texture.

Native to the temperate volcanic slopes of Chile and Argentina, Araucaria araucana is one of the world’s oldest surviving conifer species and is considered a living fossil. The species is biologically notable for extreme longevity, resistance to harsh mountain climates, and large edible seeds. In spread form, the tree emphasizes broad horizontal geometry and monumental structural branching, creating one of the most distinctive and architecturally dramatic evergreen silhouettes among ancient conifers.
