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 recognized for its clusters of pale yellow to creamy-white, pea-like blooms. Flowering from late spring into summer, it adds subtle colour to grasslands, roadsides, and open woods while attracting a variety of pollinators, especially bumblebees.

As a nitrogen-fixing plant, Yellow Hedysarum enriches soils and supports the growth of surrounding vegetation. Its deep taproot and extensive root system make it drought-tolerant and effective at stabilizing soil. Grizzly bears are known to dig up and eat the nutritious taproot. Its resilience and ecological value make it well-suited for restoration, naturalization, pollinator gardens, and erosion control projects.
