A hardy, perennial rush native to coastal and estuarine areas of Australia, Juncus kraussii forms dense clumps of tall, cylindrical green stems. It thrives in saline, waterlogged, or sandy soils and tolerates full sun to partial shade.
 
Salt Marsh Rush is highly valued in revegetation and erosion-control projects for stabilising shorelines and wetlands, providing habitat for wildlife, and enhancing coastal biodiversity.
