Maximilian Sunflower is a tall, robust perennial reaching 3–10 feet, producing masses of bright yellow flowers in late summer and fall. Native to the Great Plains, it spreads by rhizomes to form large, showy colonies that provide spectacular autumn displays. Named for Prince Maximilian of Wied, who observed it during his 1830s expedition up the Missouri River. It is an important late-season nectar source when few other flowers bloom.
