Cyperus-like Sedge
Yellow Hedysarum

Cyperus-like Sedge is a native perennial sedge found in wetlands, marshes, swamps, and along shorelines. Classified as an obligate wetland species, it grows in dense clumps that thrive in saturated soils, helping stabilize wet ground and protect shorelines. These colonies also provide cover for wildlife, while the seeds may be eaten by waterfowl and other birds. It is well-suited to wetland restoration, waterside and riparian zone plantings, and naturalization projects.
Its ornamental appeal comes from the contrast between the upright male floral spikes at the top of the stems and the long, drooping female floral spikes that hang below. These seed spikes resemble those of Cyperus species, giving the plant its common name and making it an attractive addition to naturalized plantings.

Yellow Hedysarum is a native perennial wildflower recognised for its clusters of bright yellow pea-like blooms. It adds colour to grasslands, roadsides, and open woods. It is also a nitrogen fixer, which helps improve soil fertility. Because of its deep root system, it contributes to slope and soil stabilisation.

The plant provides forage for wildlife and cover for small animals, especially its roots. Its flowers attract pollinators such as bees.

Yellow Hedysarum plays an important role in prairie and foothill ecosystems. It is well-suited for ecological restoration, naturalisation, pollinator gardens, and erosion control projects.
