Araucaria heterophylla (Salisb.) Franco
Norfolk pine, Norfolk Island pine
Norfolk Island pine isn’t a pine, but it is from Norfolk Island, and nowhere else. Norfolk Island is between Australia and New Zealand. They are popular as house plants in America.
Plants: In natural settings, trees reach 164–213′ (50–65 m), with a neat conical Christmas-tree shape. See also the similar-appearing monkey-puzzle tree and New Caledonia pine.
Leaves: Needle-shaped, sharp-tipped but soft to the touch, almost like moss. Each needle is ⅜–½″ (1–1.5 cm) in length and about 1/32″ (1 mm) around. On older trees, the needles reach up to ⅜″ (1 cm) and up to ⅛″ (4 mm) around. The thickest leaves are at the top, along with the cones.
Fruits: Cones are cylindrical, 1–3″ (2.5–7.6 cm) long. Female cones are spherical in shape, and 3–5″ (7.6–12 cm) around.
Habitats: Humid subtropical climates, in sandy soils and seacoasts.
