Slender Wheatgrass
Yellow Hedysarum

Slender Wheatgrass is a native perennial bunchgrass common across North America. It establishes quickly, making it effective for site recovery.
It produces upright seed heads that provide seasonal interest and seed for wildlife, and favoured for browsing by elk and sheep. Its seeds are eaten by birds and small mammals, and it provides cover for wildlife.
Slender Wheatgrass is among the first native grasses used for reclamation in western Canada and the U.S. It does exceptionally well in saline soils.

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.
