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.

Showy Aster is a native perennial wildflower recognized for its tall stems topped with clusters of light purple blooms. Blooming from late summer into autumn, it provides an important late-season source of nectar and pollen for pollinators. It also produces seeds that are eaten by birds, extending its value to wildlife beyond the flowering season.

Drought tolerant once established, Showy Aster grows well in urban, rural, and disturbed sites. With its mix of ecological value and ornamental appeal, it is ideal for pollinator gardens, naturalization projects, and ecological restoration.
