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.

The Majestic Magenta is a compact ground cover plant that blooms with small, rich magenta flowers in early to mid spring. In spring expect an abundance of these star-shaped flowers.

The Majestic Magenta attracts the attention of birds and butterflies and this plant is popular for it’s low maintenance and salt-tolerance.
