Rocky Mountain Fescue
Hairy Golden Aster

Rocky Mountain Fescue is a native perennial bunchgrass recognized for its fine-textured clumps and adaptability to harsh environments. It grows well in dry, rocky, and nutrient-poor soils and is highly cold-tolerant, making it well-suited to both prairie and alpine habitats. Its fibrous root system contributes to soil stability and helps reduce erosion on slopes and shallow soils.
Widespread across western and northern North America, Rocky Mountain Fescue is an important component of many prairie and alpine ecosystems. It contributes ground cover and organic matter that support soil function, provides cover for small wildlife, and offers moderate forage for grazing animals. Hardy and versatile, it is used in ecological restoration, naturalization, and habitat enhancement projects, particularly in upland and alpine landscapes.

Hairy Golden Aster is a native perennial wildflower known for its clusters of bright yellow, daisy-like blooms. They bloom from mid-summer into fall, providing late-season colour and a valuable nectar source for pollinators, including a variety of bee species.

Flowers mature into fluffy seed heads and can self-seed readily. Removing spent blooms helps manage their spread, but some people will choose to leave a few seed heads to provide food for birds. Hairy Golden Aster grow in bushy clumps, tolerates poor sandy soils, and once established, are among the most drought-tolerant wildflowers. They are well-suited for pollinator gardens, restoration, naturalization, and xeriscaping projects.

As a perennial, it dies back to the crown each winter, it will regrow from the base in the spring. Avoid disturbing the crown during late winter to ensure healthy growth the following season.
