Coreopsis /ˌkɒriːˈɒpsɨs/[4] is a genus of flowering plants in the family Asteraceae. Common names include calliopsis and tickseed, a name shared with various other plants. They range from 46–120 cm (18–47 in) in height. The flat fruits are small and dry and look like bugs. Many of its 35 to 114[5] species are cultivated. 28 species are native to North America and the others come from Central and South America. The flowers are usually yellow with a toothed tip. They have showy flower heads with involucral bracts in two distinct series of eight each, the outer being commonly connate at the base. The name Coreopsis is derived from the Greek words κορις (koris), meaning "bedbug," and ὄψις (opsis), meaning "view," referring to the shape of the achene.[6]
Coreopsis species are used as food plants by the caterpillars of some Lepidoptera species including Coleophora acamtopappi.
Coreopsis is closely related to Bidens. In fact, neither Coreopsis nor Bidens, as defined in the 20th century, is monophyletic. One group which does seem to be monophyletic consists of temperate species from North America, including five sections of Coreopsis, Bidens coronata and Bidens tripartita, and the genus Thelesperma (five species).[2]
All Coreopsis species were designated the state wildflower of Florida in the United States in 1991.[7]
