Smooth Aster

Pinegrass is a hardy, native perennial grass common in forested regions of western North America. It is an important understory species and is typically found beneath conifer canopies. Due to its spreading nature and ability to form dense mats that cover the forest floor, it helps stabilize soils and reduce erosion.

It provides forage for wildlife and livestock, shelter for small animals, and seeds for birds, playing an important ecological role in woodland ecosystems. Pinegrass is well-suited for ecological restoration, soil stabilization, and naturalization projects.

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.
