Bolboschoenus caldwellii

Bolboschoenus caldwellii, or Marsh Club-rush, is a robust, rhizomatous sedge native to Australia, commonly found in wetlands, swamps, and along the edges of rivers and lakes. Growing up to 1.5 meters tall, it features erect, triangular stems and clusters of spikelets that form compact, brownish flower heads. Its dense root system and spreading rhizomes make it an effective plant for stabilizing soils and managing erosion in wetland environments.

This species thrives in waterlogged soils and shallow water, tolerating periods of inundation and fluctuating water levels, making it ideal for ecological restoration and constructed wetlands. Marsh Club-rush provides critical habitat and food for aquatic wildlife, including waterbirds and insects, contributing to wetland biodiversity.

Bolboschoenus caldwellii is a practical and visually appealing choice for riparian plantings, wetland rehabilitation, and naturalistic water features, offering ecological benefits while enhancing the aesthetic of water-based landscapes.
