Smooth Aster is a native perennial wildflower known for its violet-blue, daisy-like flowers. They bloom later in the season, from late summer to early fall. The flowers attract a variety of pollinators, including bees, butterflies, and other beneficial insects. It also serves as a host plant for the Silvery Checkerspot (Chlosyne nycteis) and Pearl Crescent (Phyciodes tharos) butterflies, further enhancing its ecological value. This easy-to-grow wildflower is well suited for native wildflower gardens, pollinator gardens, and naturalization projects.

The Smooth Aster’s non-aggressive root system allows it to spread slowly, and it is more likely to reproduce by seed, which can be controlled through deadheading. 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.

Bluebunch Wheatgrass is a native perennial bunchgrass common across prairies, foothills, and open woodlands. It has a long life span, unlike many other grasses.
This grass competes well with invasive species, has extensive root systems and is drought tolerant. It provides forage for deer, elk, bighorn sheep, and is extremely palatable by livestock. Its seeds are eaten by birds and small mammals, while its dense clumps offer nesting and shelter.
