Additional Information: Stiff Sunflower is a durable prairie wildflower known for its bright yellow sunflower-like blooms that appear late in the growing season. It naturally occurs in prairies, roadsides, and open fields, where it thrives in full sun and tough soil conditions. The plant forms upright stems and can spread gradually to form patches, making it well suited for prairie plantings and naturalized landscapes. Its late-season flowers provide nectar for bees and butterflies, while the seeds later offer food for birds. With its strong stems and drought tolerance, Stiff Sunflower is a reliable choice for sunny native gardens.
