The Araucaria heterophylla, commonly known as the Norfolk Island Pine, is a majestic evergreen that adds a stately and exotic touch to any setting. Its symmetrical shape and soft, tiered branches make it a popular choice both as an outdoor landscape feature and as a traditional indoor Christmas tree.
Evergreen or Deciduous: Evergreen
Mature Height (metres): Typically grows to about 15-20 metres in landscape settings, much taller in its native habitat.
Mature Width (metres): Approximately 5-7 metres.
Spacing: Plant at least 6-8 metres apart from other trees or structures to accommodate its expansive spread and ensure proper growth.
Foliage: Features soft, dense, and lush green needles that are arranged in whorled branches, creating a visually pleasing, tiered pattern.
Flowering Period: Does not produce conspicuous flowers; valued mainly for its foliage and architectural form.
Fruit: The tree occasionally produces cones, but they are generally not considered a decorative feature.
Form/Habit: Upright and pyramidal, often with a single straight trunk, perfect for achieving a vertical accent in large garden spaces or parks.
Uses: Widely used as a focal point in large gardens, parks, and coastal areas. Its tolerance to salt makes it suitable for seaside planting. Also commonly used as a potted specimen for indoor or outdoor decoration, especially during the festive season.
Sun: Prefers full sun to partial shade. More sunlight ensures denser foliage.
Maintenance: Low; requires little pruning apart from removing any damaged or diseased branches to maintain health and appearance.

The Araucaria heterophylla is truly a versatile plant that combines robust growth with ornamental appeal, making it a favourite for gardeners and landscapers looking for an imposing yet attractive tree to enhance their green spaces.
