Cyperus lucidus

Cyperus lucidus, or Leafy Flat-sedge, is a robust, clump-forming perennial sedge in the family Cyperaceae, native to Australia. Commonly found in wetlands, along watercourses, and in moist grasslands, it thrives in swamps and stream banks in areas with higher rainfall. Growing up to 1.5 meters tall, this large tussocking sedge features upright triangular stems and long, glossy, bright green leaves with swollen partitions. The leaves, which can reach up to 40 cm in length, have rough margins and create a bold, architectural presence in wetland landscapes.

From spring to summer, Cyperus lucidus produces spikelets of small brown flowers clustered along elongated stalks. These flowers are surrounded by leaf-like bracts, adding texture and interest to its tubular stems. Its distinctive features include its large stature, leaf-like bracts among the flowers, and sharp-edged leaf blades. These characteristics make it one of the most visually striking sedges in its habitat. While it remains the most widespread Cyperus species in Victoria, particularly in the south, it is now considered rare on the volcanic plains.

Thriving in waterlogged soils and tolerating full sun to partial shade, Leafy Flat-sedge is ideal for wetland restoration, riparian planting, and erosion control.

With its bold foliage, ecological importance, and adaptability to moist environments, Cyperus lucidus is a valuable choice for wetland rehabilitation, water-sensitive landscaping, and biodiversity-focused projects. Its ability to enhance both the functionality and aesthetics of natural and designed landscapes makes it a standout species in wetland ecosystems.
