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.

Twinflower is a native, trailing evergreen ground cover known for its delicate flowers that grow in nodding pairs. These pale pink blooms are described as being sweetly fragrant, attracting native bees and other pollinators.
Growing in cool, moist, acidic soils, the trailing stems form roots as they spread and start to form mats across the forest floor. Due to its woody stem, it is technically classified as a shrub and often referred to as a subshrub or dwarf shrub. This species is well-suited for naturalization, restoration, and conservation projects.
Twinflower (Linneae borealis) was named in honour of Carl Linnaeus, who adopted it as his personal emblem.
