Flowering Raspberry
Smooth Aster

The Flowering Raspberry is an ornamental shrubby plant that blooms with fragrant light purple flowers throughout the summer and has a large, decorative foliage of bright green leaves. The flowers resemble that of a wildrose, and the foliage turns a bright yellow in the fall. This cultivar produces small red raspberries, similar to that of a thimbleberry, but the fruit is mostly tasteless.

The Flowering Raspberry, also known as Virginia Raspberry or Purple-Flowered Raspberry, makes a great hedge plant and is a good choice for attracting birds to your yard.

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.
