50 Seeds Maximilian Sunflower Helianthus maximiliani Perennial Wildflower
Maximilian Sunflower is a tall, clump-forming perennial known for its abundant golden-yellow blooms that open late in the season. A North American native prairie species, it brings vertical interest and a naturalistic look to meadows, borders, and wildflower plantings, and its late bloom period extends seasonal color long after many other flowers have finished.
This species is well suited to prairie restorations, pollinator gardens, native plant landscapes, and low-maintenance borders. Its sturdy stems hold numerous blooms and it spreads gradually by rhizomes to form substantial colonies over time. Tolerant of heat and dry conditions once established, it works well massed at the back of a border or naturalized in open ground.
