Dianthus is a genus of about 300 species of flowering plants in the family Caryophyllaceae, found mainly in Europe and Asia, with a few species found south to north Africa, and one species (D. repens) in Arctic North America. Common names include carnation (D. caryophyllus), pink (D. plumarius and related species) and sweet william (D. barbatus). The name Dianthus is from the Greek words dios ("god") and anthos ("flower"), and was mentioned by the Greek botanist Theophrastus.
