Araucaria heterophylla holds perfectly symmetrical tiers of horizontal branches around a dead-straight central trunk, giving an architectural precision that no other large tree in Australia matches. It is the tree that defines the skyline of Australian coastal towns.
The Norfolk Island Pine is a very large tree, reaching 50 to 65 metres tall and 15 to 20 metres wide over its lifetime at 40 to 70 centimetres per year. It needs genuine space and is best suited to foreshores, parkland, civic landscapes and large properties rather than suburban gardens.
This species is exceptionally tolerant of salt spray, sand and constant onshore wind, which is why it is planted along exposed foreshores where little else survives. It grows in full sun to part shade, tolerates light to moderate frost once established, and needs no ongoing maintenance.
Frequently Asked Questions
About Araucaria heterophylla
How big does Araucaria heterophylla grow?
The Norfolk Island Pine reaches 50 to 65 metres tall and 15 to 20 metres wide at full maturity. It is a very large tree and needs to be sited with that eventual size in mind.
Is the Norfolk Island Pine salt tolerant?
Yes. It is among the most salt and wind tolerant large trees available, which is why it is used along exposed foreshores and beachfront reserves throughout Australia.
How fast does Araucaria heterophylla grow?
It grows at 40 to 70 centimetres per year, which is moderate for a tree of its eventual size. Growth is steady and the symmetrical form develops from a young age.
Is the Norfolk Island Pine suitable for a suburban garden?
Generally no. Its mature size demands parkland scale. On a standard suburban block it will outgrow the space and overwhelm the garden within a few decades.
Can Norfolk Island Pine be grown in a pot?
Young plants are commonly grown in pots and hold their symmetrical form well for several years, but they eventually need to be planted out or replaced as they outgrow container culture.
Is Araucaria heterophylla frost tolerant?
It handles light to moderate frost once established, though it performs best in frost-free coastal conditions. Young plants should be protected in cold inland districts.
How far apart should I plant Norfolk Island Pines?
For an avenue or foreshore row, plant 8 to 10 metres apart. As individual feature trees allow a minimum of 15 metres clear of buildings and services.
