Coreopsis grandiflora is a North American species of perennial plants in the sunflower family. The common name is large-flowered tickseed.[4] It is found in eastern Canada (Quebec, Ontario, New Brunswick) and much of the United States, especially the south-central part of the country (Oklahoma, Arkansas, etc.).[5] The species is widely cultivated in China and naturalized there.[6]

Coreopsis grandiflora is a perennial sometimes greater than 60 cm (2 feet) tall. It produces yellow ray and disc flowers.[7]
