Hairy Golden Aster
Smooth Aster

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.

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.
