Large-flowered Tickseed

Coreopsis grandiflora

Also known as Largeflower Tickseed, Golden Coreopsis

Bright golden-yellow blooms with deeply notched petal tips make large-flowered tickseed a standout across prairies, roadsides, and sunny gardens. Native bees, hoverflies, and butterflies flock to the prominent central discs throughout summer, while songbirds later feast on the dry, tick-like seeds. This resilient wildflower thrives in nutrient-poor soils and drought-prone spots where many other garden plants struggle.
