Anthony Waterer Spiraea

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.

Anthony Waterer Spiraea is a low maintenance shrub with a dwarf, rounded form. In spring and summer rosy pink blooms emerge against green foliage. Its tolerance of a variety of well-drained soils makes it an ideal foundation, landscaping, or border plant.

If deer and rabbit are an issue on your property, consider planting Anthony Waterer Spiraea for its deer/rabbit resistance. Due to its compact form, minimal pruning is required.
