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 to 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.
Specimen & Installation
Spacing (screening/hedge): 3 to 5m
Spacing (feature/avenue): 6 to 10m
Best Planting Season: Autumn to spring
Soil & Drainage: Tolerates a wide range of soils including heavy clay, saline and waterlogged conditions; highly adaptable to poorly drained sites
Establishment Care: Water regularly for the first 1 to 2 summers until established, then reduce to occasional deep watering during extended dry periods. Mulch around the base to retain moisture and suppress weeds during establishment.
