Araucaria heterophylla - Norfolk Island Pine

The Norfolk Island Pine is a very large evergreen conifer, slow growing to 100'. It has a very formal growth habit with a strong pyramidal shape and whorled lateral branches. Lateral branches very symmetrical as well, slightly arching upwards and appearing flat tiered. There is often a large space between the whorls of branches, especially on young trees. Commonly seen as a house plant. I have seen this tree planted in so many wrong spots, right up against a house, a fence or the street.

Leaves evergreen, simple, linear, 1/4 - 1/2" long, triangular in cross section, radiating around the stem, curved in the middle of the leaf and pointing forward. Very soft. Dark shiny green. Leaves on young stems longer, those on the mature portion shorter and more broad while the leaves on fertile branches are much different, more triangular shaped and tightly arranged. (Hence the name heterophylla)

Globose cones on the ends of the branches of mature trees, 3.5 - 5" long and green at maturity.

Male cones 1.5" long, catkin like. One reference suggests that males are only produced on trees 40+ years old. (Norfolk Island Botanical Gardens home page, accessed 1998, now defunct).

Bark is think, smooth, greenish brown.

Misidentification: There is a second species in cultivation that is very similar to this one. References suggest that most plants originated as nursery stock from Hawaii are A. columnaris which has a much thinner spread of lateral branches, and smaller leaves. (Eckenwalder 2009.)
