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.

Common Gaillardia is a native perennial wildflower known for its vibrant, daisy-like blooms. Flower petals vary in color from two-tone blooms with an orange-red center and yellow tips to solid yellow. Blooming from early summer to fall, it provides continuous color while attracting bees, butterflies, and other pollinators. The seeds also serve as a food source for birds, adding to its ecological value.

Common Gaillardia is easy to grow and can tolerate heat and drought. If flowering slows in the summer heat, cutting back the plant can encourage a new round of blooms in the fall. It is ideal for pollinator gardens, xeriscaping, naturalization projects, and ornamental plantings.

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.
