About plant names...

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.

Identification: In natural settings, trees reach 164-213' (50-65 m), with a neat conical Christmas-tree shape. Leaves are 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. 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. See also the similar-appearing monkey-puzzle tree.
