Overview & Specifications
Swamp She-oak - Casuarina obesa
Where most trees fail, Casuarina obesa performs. A robust Australian native built for wet, saline, and coastal conditions, it delivers sweeping, fine-textured screening and enduring structural presence in the most demanding landscape scenarios.
Why Swamp She-oak
Wet and waterlogged tolerance: One of the few large natives that actively thrives in boggy, poorly drained, and flood-prone sites.
Saline and coastal resilience: Handles salt-laden soils and coastal exposure where conventional species deteriorate.
Distinctive fine foliage: Pendulous branchlets introduce soft movement and refined texture to large-scale plantings.
Proven native adaptability: Naturally conditioned to challenging Australian conditions with minimal intervention.
Long-term structural value: Matures to 8–15 metres, forming a substantial canopy that anchors the landscape for decades.
Ideal Applications
Problem-site resolution: The first-choice species for low-lying, saline, or persistently wet areas on residential and commercial properties.
Coastal screening and shelter: Provides reliable wind protection and privacy buffering in exposed seaside landscapes.
Large-scale revegetation: Well-suited to acreage, infrastructure corridors, and ecological restoration projects.
Native and bushland compositions: Integrates seamlessly into curated native landscapes and waterway plantings.
