Establish large-scale windbreaks, shelterbelts, or restoration 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, and agricultural protection.

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

As a nitrogen-fixing tree, it improves soil quality and supports sustainable land management. It responds well to pruning, pollarding, and coppicing to create dense living fences and wind barriers. This extra-large bulk quantity is ideal for farms, ranches, reforestation efforts, erosion control, coastal stabilization, and nursery production.
