Araucaria heterophylla (synonym A. excelsa) is a vascular plant in the ancient and now disjointly distributed conifer family Araucariaceae. As its vernacular name Norfolk Island pine (or Norfolk pine) implies, the tree is endemic to Norfolk Island, a small island in the Pacific Ocean between New Zealand and New Caledonia, about 1440km east of Sydney, Australia.

The genus Araucaria occurs across the South Pacific, especially concentrated in New Caledonia (about 700 km due north of Norfolk Island) where 13 closely related and similar-appearing species are found. It is sometimes called a star pine, Polynesian pine, triangle tree or living Christmas tree, due to its symmetrical shape as a sapling, although it is not a true pine. It is a slow growing tree, reaching a height of 50–65 m, with straight vertical trunks and symmetrical branches, even in the face of incessant onshore winds that can contort most other species. From the straight trunk, it emits its branches almost horizontal or slightly oblique, in number of five, forming floors; the plane of each floor is a perfect pentagon. If kept indoors, the tree remains smaller. The gray-brown bark falls off in fine scales. At the more or less horizontal to sometimes hanging branches, the branches are four to seven in regular whorls.

The young leaves are soft and awl-shaped, 1–1.5 cm long, about 1 mm thick at the base on young trees, and incurved, 5–10 mm long and variably 2–4 mm broad on older trees. The thickest, scale-like leaves on coning branches are in the upper crown. The cones are squat globose, 10–12 cm long and 12–14 cm diameter, and take about 18 months to mature. 

They disintegrate at maturity to release the nut-like edible seeds.

The seeds have a length of 2.5 to 3 cm and a diameter of about 1.2 cm with wide wings. There are four cotyledons present. It is a dioecious tree (male and female flowers in different plants), although it can also be monoecious.

The scientific name heterophylla ("different leaves") derives from the variation in the leaves between young and adult plants. 

The distinctive appearance of this tree, with its widely spaced branches and symmetrical, triangular outline, has made it a popular cultivated species, either as a single tree or in avenues. When the tree reaches maturity, the shape may become less symmetrical. Despite the endemic implication of the species name Norfolk Island pine, the species is widely planted as an ornamental tree for its exotic, pleasing appearance and fairly broad climatic adaptability, and now occurs throughout the world in regions with suitable Mediterranean and humid subtropical climate. It grows well in deep sand, as long as it receives reliable water when young. This, and its tolerance of salt and wind, make it ideal for coastal situations. Indoors, the plant needs a bright, cool location for good growth. In summer it must not be exposed to the blazing sun; the temperature should not exceed 18 degrees Celsius. In winter, the plant needs a bright room that should be at least between 5 and 10 degrees Celsius.

Many of the "Norfolk Island pines" that grow in Hawaii, including their descendants used as potted ornamentals on the U.S. mainland, are actually Cook pines, the two species having been confused when introduced.

Young trees are often grown as houseplants in areas where the winters are too cold for them to grow outside (they will not, for example, survive outdoors in most of North America or Europe), and are sometimes used as Christmas trees. It will not survive in areas subject to prolonged cold. However, there are a few specimens growing outdoors in the subtropical gardens of Tresco Abbey Gardens on the Isles of Scilly, in the United Kingdom. What is probably the most northerly specimen growing outdoors is a young tree on Valentia Island on the southwest coast of Ireland. The tendency for potted saplings to develop a barren appearance can be helped by growing them in clumps. In northern climates they can be left outdoors during summer to promote fuller growth.

Large numbers of Norfolk Island pines are produced in south Florida for the houseplant industry. The bulk of these are shipped to grocery stores, discount retailers and garden centres during November. Many of these are sprayed with a light coating of green paint prior to sale to increase their eye appeal, although this may weaken or even kill the plant if it cannot photosynthesize adequately.

Some areas in the southern USA deserts and subtropical Florida prohibit the planting of Norfolk Island Pine due to the fact they can be struck by lightning and fall”. Information retrieved from Wikipaedia 2019

TO GROW:

Seed germinates fairly rapidly (10-15 days).
Seed should be placed flat on the germination medium without covering and lightly misted or fogged until the tap root emerges and top growth is initiated.
At that time, seedlings can be irrigated as needed to keep the medium moist.
Suggested light level for propagation is 50% shade.
Often about 5% albino seedlings will germinate and these will die or can be discarded when potting seedlings.
