Coreopsis (/ˌkɒriːˈɒpsɪs/[2]) is a genus of flowering plants in the family Asteraceae. Common names include calliopsis and tickseed, a name shared with various other plants.

These plants range from 46–120 centimetres (18–47 inches) in height. The flowers are usually yellow with a toothed tip, but may also be yellow-and-red bicolor.[3] They have showy flower heads with involucral bracts in two distinct series of eight each, the outer being commonly connate at the base.

Distribution and habitat
North American Coreopsis can be found in two habitats in the wild, growing along roadsides and open fields throughout the Eastern United States and Canada. In this environment the plant will self-sow.
Ecology
Coreopsis species are a source of nectar and pollen for insects.[3] The species is known to provide food to caterpillars of some Lepidoptera species, including Coleophora acamtopappi.
Cultivation
Coreopsis can grow in a garden as a border plant, or in a container, preferring well-drained soil. Deadheading the flowers ensures it does not become weedy. Using the
The sunny, summer-blooming, daisy-like flowers are popularly planted in gardens to attract butterflies. Both
Culture
All Coreopsis species were designated the state wildflower of the U.S. state of Florida in 1991.[10] In the language of flowers, Coreopsis means to be always cheerful, while Coreopsis arkansa in particular stands for love at first sight.[11]
