Rough Fescue is a native perennial bunchgrass valued for its tall, dense clumps and long-lived growth. Adapted to cold climates and nutrient-poor soils, it is a defining species of northern prairie and montane grasslands. In western Canada and the northern Rocky Mountains, Rough Fescue is considered a keystone species because it shapes plant communities, stabilizes soils, and supports ecosystem resilience.

It is a cool-season grass, growing most actively in spring and fall and slowing during the heat of summer. Rough Fescue is highly regarded as forage for wildlife and livestock, with elk, deer, and other grazing animals favoring it. Taller than many other fescue species, it is well-suited to prairie restoration, erosion control, and naturalization projects where it supports both biodiversity and long-term ecosystem health.

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.
