The genus Coreopsis L. is Florida’s state wildflower; there is a strong interest in commercial production and large-scale planting of Coreopsis seed in Florida, especially the seed of Coreopsis leavenworthi Torr. & A. Gray (COLE) and Coreopsis tinctoria Nutt. (COTI). Both species belong to the same section [Calliopsis (Reichenb.) Nutt.] within Coreopsis and were known…
The objectives of this project are to assess (1) the potential loss of genetic diversity (or genetic shift) during seed production of C. leavenworthii, and (2) potential gene flow from C.tinctoria to C. leavenworthii, two important issues in production and use of C. leavenworthii seeds. We have made excellent progress toward these objectives and have…
Florida tickseed (Coreopsis floridana) is one of 12 Coreopsis species native to Florida. It is endemic to the state and occurs naturally in wet pinelands and prairies, cypress swamp edges and roadside ditches. It typically blooms from late summer into early winter, but may bloom year-round. Its bright sunny flowers attract a variety of pollinators, especially butterflies.
Anne MacKay received the 2019 T. Elizabeth Pate Coreopsis Award during the Florida Wildflower Symposium on April 13 in recognition of her advocacy for Florida’s wildflowers. For 20 years, Anne has steered work for Florida’s wildflowers, first serving on the Florida Wildflower Advisory Council, then on the Florida Wildflower Foundation’s board of directors, on which she served as chair.

The Florida Wildflower Foundation selects retiring Florida Department of Transportation Landscape Architect Jeff Caster to receive the 2020 Coreopsis Award for his lifetime of devotion to Florida’s wildflowers.
by Claudia Larsen Follow this new species' journey from discovery to naming Recently discovered in North Florida's Jackson County, Coreopsis bakeri has gone undetected for years because of its resemblance to our common lanceleaf tickseed (Coreopsis lanceolata). Several years of scientific study finally proved that, indeed, it is has been isolated long enough to have...
Lanceleaf tickseed (Coreopsis lanceolata) has conspicuously sunny flowers that typically bloom in spring. It attracts butterflies and other pollinators, and its seeds are eaten by birds and small wildlife.
Leavenworth’s tickseed (Coreopsis leavenworthii) it is often used as a component of mixed wildflower and butterfly gardens, and is excellent for sunny roadsides, highway medians and powerline easements.
Swamp tickseed (Coreopsis nudata) blooms in spring and is attractive to bees, although butterflies and other pollinators are known to visit them. Birds eat its seeds.
Dr. Walter K. Taylor, University of Central Florida professor emeritus of biology, has received the Florida Wildflower Foundation’s T. Elizabeth Pate Coreopsis Award for his lifetime of contributions to La Florida, “land of flowers.”
A concern was recently raised about planting two species of Tickseed (Coreopsis spp.) near each other in a garden because the two might hybridize. If they were both Florida ecotypes, so what if they did? We share what research has shown us about this intriguing issue.
