Maximilian's sunflower is a tall native perennial that produces masses of bright yellow daisy-like flowers from late summer through fall. This prairie wildflower forms upright clumps and can reach up to 7 feet tall, making it an excellent backdrop plant for naturalized areas.
In an HOA neighborhood
Maximilian's Sunflower 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 height appears wild and uncontrolled
- Can spread aggressively through underground rhizomes
- Dies back completely leaving tall brown stalks in winter
Wildlife value
The abundant late-season blooms provide crucial nectar for migrating butterflies and native bees when few other flowers remain. Seeds attract goldfinches and other songbirds through winter.
Native range data from the USDA PLANTS Database and regional native plant society lists. Pollinator and host plant associations compiled from GBIF, iNaturalist, and published ecological literature.
