Annual Coreopsis, Calliopsis
Easy-to-grow members of the sunflower family yielding a profusion of yellow, orange, maroon, or reddish flowers. Deadhead for longer bloom; use hedge shears to remove large numbers of spent blooms. Both annual and perennial kinds are easy to propagate—annuals from seed sown in place or in pots, perennials from seed or division. Plants tend to self-sow; seeds attract birds.
The species listed here are from the eastern and southern U.S. unless otherwise noted.Coreopsis tinctoria
