Sea rush thrives in moist to waterlogged soils and is ideal for pond edges, rain gardens, or coastal plantings. It tolerates salt spray and partial shade, making it a tough, low-maintenance choice for challenging wet spots. Minimal feeding or pruning is required; simply ensure the soil never fully dries out.
