Flat Topped White Aster
Doellingeria umbellata
Flat-Topped White Aster provides a late-season burst of white flowers. It grows up to an impressive 6 feet tall, producing slender, branching stems topped with flat clusters of small, white blooms with yellow centers. These delicate flowers attract pollinators and add lightness to meadows, borders, and rain gardens. This aster thrives in full sun to partial shade and moist, well-drained soils, making it perfect for naturalistic plantings, wet meadows, and pond edges.

Maintenance Tips
- Deadhead to promote additional blooms and prevent excessive self-seeding.
- Prefers moist, fertile soil but is adaptable to various soil types.
- Divide clumps in early spring every few years to rejuvenate growth and manage plant spread.
- Well-established plants can be cut back to roughly 2/3 or 1/2 their height in early summer to reduce overall height and increase bushiness if this is a consideration for your yard.
