Coreopsis

 

(tickseed), a genus of plants of the family Compositae. They are annual or perennial grasses; less often they are subshrubs or shrubs. The leaves are entire or dissected. The inflorescence is a head, usually with infertile ligulate flowers and bisexual tubular disk-flowers. The achenes have poorly developed awns or are awnless. There are approximately 120 species, distributed primarily in America; less frequently they are found in tropical Africa and on the Hawaiian Islands. Several species are used as ornamentals, including the annuals Coreopsis tinetoria and golden wave (C. basalts, or C. drummondii ) and the perennial C. grandiflora. The forms and varieties of C. tinctoria and golden wave are distinguished by their height (15–100 cm) and by the color of the ligulate flowers (yellow, dark red, reddish brown, or bicolor). C. grandiflora is cultivated particularly for cutflowers.
