Umbellate aster is a tall perennial wildflower that produces clusters of small white flowers from summer through fall. This native plant forms clumps and can reach up to 5 feet tall, making it suitable for back borders or naturalized areas. It dies back completely in winter and emerges fresh each spring.
In an HOA neighborhood
Umbellate Aster takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Very tall and can appear weedy
- Dies back completely leaving bare ground in winter
- May spread and look uncontrolled
Wildlife value
The abundant small flowers attract a wide variety of pollinators including native bees, butterflies, and beetles throughout the long blooming season. Seeds provide food for birds in late fall.
