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.

Russian Almond is a low maintenance, short, slightly suckering shrub. It is covered with attractive, bright pink flowers in early spring before its foliage emerges.

This hardy species forms dense thickets attracts wildlife. Russian Almond prefers full sun and well-drained soils, but can tolerate moist soils.

The nuts it produces are quite attractive but very small. They are bitter and possibly toxic in large quantities.
