100 Seeds Flat-Topped Aster Doellingeria umbellata Native Wildflower Pollinator Garden

Flat-Topped Aster (Doellingeria umbellata) is a native perennial wildflower that produces broad, flat clusters of small white blooms atop upright stems in late summer into autumn, bringing a clean, airy texture to naturalistic plantings. Its open flower heads sit like small landing platforms above medium-green foliage, creating a welcoming display through the end of the growing season.

This aster works well in meadow gardens, pollinator plantings, rain gardens, and native wildlife areas, where its late-season flowers are followed by fluffy seed heads that add winter interest. The plants grow best in full sun to part shade and tolerate a range of moisture levels, from average to consistently moist soils, making them a versatile choice for borders and naturalized landscapes.
