False Sunflower

Heliopsis helianthoides

Also known as Rough Oxeye, Smooth Oxeye, Oxeye Sunflower

False sunflowers illuminate prairies and open meadows across North America with long-lasting, daisy-like bright yellow flower heads. Unlike true sunflowers, both the disk and ray florets produce viable seeds, forming dense seed heads that persist into winter. These hardy perennials thrive in tough soils, providing vital nectar for native bees, butterflies, and beneficial insects.

Responsible observation
  • Sunlight Needs: Plant in full sun to partial shade for the strongest stems and abundant flowers.
  • Garden Care: Deadhead spent blooms in midsummer to prolong the flowering season into autumn.
  • Winter Wildlife: Leave mature seed heads intact over winter to feed overwintering songbirds.
