Pearly Everlasting
Smooth Aster

Pearly Everlasting is a native perennial wildflower known for its clusters of white, papery flowers with yellow centres. These long-lasting blooms appear throughout summer, and the silver-grey foliage adds contrast to the landscape. Its nectar supports a variety of pollinators and serves as a host plant for painted lady caterpillars.

Pearly Everlasting is also used in dried flower arrangements. It is well-suited for pollinator gardens, naturalization, ecological restoration, and low-maintenance landscapes.

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.
