White Meadowsweet
Smooth Aster

White Meadowsweet is a woody, deciduous shrub that begins to bloom in early summer with small white and pink flowers. Its foliage turns from a light green into an attractive golden-yellow later in the fall.

The White Meadowsweet, also known as Mead-Wort or Bride-Wort, is favored by birds and butterflies but is largely ignored by deer. They produce small brown berries in the summer, and while they are technically edible, they are not sweet and are more desired by wildlife.

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.
