Norfolk Island Pine
Araucaria heterophylla, commonly called the Norfolk Island Pine, is a symmetrical evergreen conifer prized for its perfectly tiered branches and architectural form. Although often sold as an indoor Christmas tree, it is actually a long-lived outdoor feature tree that thrives in mild coastal climates — making it surprisingly suitable for many parts of Melbourne, especially bayside and sheltered suburbs.

Quick Summary
The Norfolk Island Pine is less of a garden filler and more of a living sculpture — ideal where a single elegant tree is needed rather than dense shade. In Melbourne landscapes it performs best as a sunny, sheltered feature tree, particularly near the coast or in open lawns where its perfectly symmetrical structure can be appreciated.
