They range from 46–120 cm (18–47 in) in height. A Common name for Coreopsis is Tickseed. They have showy flower heads with involucral bracts in two distinct series of eight each, the outer being commonly connate at the base. The flowers are usually yellow with a toothed tip.

The 75 to 80 Coreopsis species are native to North, Central, and South America. 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 κόρις (koris), meaning "bedbug," and ὄψις (opsis), meaning "view," referring to the shape of the achene.
Coreopsis species are used as nector and pollen for insects. The species is known to specifically provide food to caterpillars of some Lepidoptera species including Coleophora acamtopappi. The sunny, summer blooming, daisy-like flowers are popular in gardens to attract butterflies. Both annual and perennials types are grown in the home garden (USDA Hardiness Zone 7a/6b). In this Mid-Atlantic region insects as bees, hover flies, wasps are observed visiting the flowers.
