Smooth Aster

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.

Wood Lily is a native perennial wildflower known for its vibrant, trumpet-shaped blooms in shades of orange to red. Its showy flowers appear mid-summer and are highly visible in meadows and prairies. The upward-facing flowers are an important nectar source for many pollinators, including native bees, butterflies, and hummingbirds.
Unlike most lilies, the Wood Lily’s flowers face upward rather than nodding. It is slow to establish and may take years before flowering, but once mature, it requires little maintenance. It is well-suited for pollinator gardens, naturalisation projects, prairie restoration, and open woodland plantings.
Wood Lily is the provincial flower of Saskatchewan and North America’s most widespread lily. Despite its wide natural range, populations have been declining. Habitat loss, overgrazing by deer, and unsustainable picking have reduced both its abundance and density across many regions. These pressures highlight the importance of protecting and restoring this once-common wildflower.
