Blue Moon Wisteria
Smooth Aster

Blue Moon Wisteria is a striking, flowering vine, and the hardiest of the wisterias. Up to three times in one growing season you can expect showy, fragrant, lavender-blue flowers.

Make sure you plan your site as this vine requires a structure to support its mature weight. Try planting close to a post, trellis, or fence.

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.
