Coreopsis is a genus of flowering plants in the family Asteraceae, which includes about 110 species of annual and perennial herbs, shrubs, and small trees. They are commonly known as tickseed, and are native to North and South America.

Coreopsis plants prefer full sun and well-drained soil, and are relatively easy to grow. They are often grown as perennials, but some species are annual. They can be propagated by seed or cuttings, and are attractive to bees and butterflies. Coreopsis plants are also relatively drought-tolerant and can be grown in containers or in rock gardens. They are often used in borders, meadows, and other naturalistic plantings.
