A late-season perennial producing flat-topped clusters of small white flowers with yellow centers, attractive to pollinators. It thrives in moist conditions and adds reliable late-summer color to native plant gardens.
Why grow it
Flat-top white aster flowers later in the season than many native asters, extending pollinator resources into fall when other options diminish. It tolerates wet soils better than many ornamental asters, making it useful for rain gardens or low-lying areas where typical asters would struggle. The distinctive flat flower clusters distinguish it visually from dome-shaped or spike-forming asters of similar bloom time.
Watch out for
This species performs best in consistently moist to wet soils and may decline if subjected to prolonged drought or poor drainage in heavy clay without amendment. In drier settings, monitor plants for reduced vigor and increased susceptibility to powdery mildew, a common issue with stressed asters.
