Establish large-scale windbreaks, shelterbelts, reforestation projects, or commercial plantings with these River She-Oak (Casuarina cunninghamiana) seeds. This fast-growing evergreen is prized for its soft, pendulous foliage and narrow upright habit, making it ideal for screening, shade, erosion control, and agricultural protection.

Native to Australia, River She-Oak thrives along riverbanks and sandy flats but adapts to a wide range of soils, including sandy, gravelly, alkaline, nutrient-poor, and urban environments. It tolerates heat, drought, salt spray, wind, and seasonal dry conditions, making it an excellent solution for coastal properties and harsh growing sites.

As a nitrogen-fixing tree, it improves soil fertility and supports sustainable land management. It responds well to pruning, pollarding, and coppicing to form dense living fences and protective wind barriers. This extra-large bulk quantity is ideal for farms, ranches, coastal stabilization, large windbreak systems, commercial nursery production, and land restoration projects.
