Seaside Arrowgrass
Yellow Hedysarum

Seaside Arrowgrass is a native perennial commonly found in wetlands, salt marshes, and moist meadows. It is especially suitable for difficult growing sites. Its dense root system helps stabilize soil, while also providing food, cover, and habitat for small animals within the wetland community.

Seaside Arrowgrass is suitable for shoreline stabilization, wetland restoration, and naturalization projects.

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.
