Florida Tickseed (Coreopsis leavenworthii)

Educational Story

The Florida Tickseed, Coreopsis leavenworthii, is in the genus that includes the Florida state wildflower. Bright yellow flowers bloom year round in sun or shade, often tolerating poor soils. It’s a fast growing perennial that re-seeds itself, making it easy to grow and enjoy. Lady Bird Johnson, first lady to the 36th President of the United States Lyndon B. Johnson, saw roadside restoration as an ecological opportunity to bring back the species richness that was once there. In 1965 the Highway Beautification Act was passed and is still upheld today by the Lady Bird Johnson Wildflower Center. Tickseed  is one of the many wildflowers used in roadside restoration projects across the southeastern United States and can be seen blanketing highway roadsides in spectacular yellow blooms, typically in the summer. It is an important food source for pollinators.
