Coreopsis, also known as tickseeds, are annual or perennial flowering plants in the family Asteraceae. They are native to temperate and subtropical regions of the world and are widely cultivated as ornamental plants. The genus includes about 80 species, with a wide range of flower colors including yellow, orange, red, and pink.

Conclusion
Coreopsis is a genus of flowering plants in the sunflower family. They are native to North America, were they are distributed from the Great Plains east to the Atlantic Coast, and south to the Gulf Coast and Mexico. Coreopsis species are annual or perennial herbs, rarely shrubs, growing to 0.5–2 m tall. The leaves are opposite or sometimes whorled, simple, and usually deeply lobed or pinnately divided; the leaf margins are dentate or serrate. The flowers are borne in flower heads with both ray florets and disc florets; the ray florets are often absent in some species. The fruit is an achene.
