Dianthus is a genus of about 300 species of flowering plants in the family Caryophyllaceae, native mainly to Europe and Asia, with a few species extending 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 cited by the Greek botanist Theophrastus.
The color pink may actually be named after the flower. The origin of the flower name 'pink' is unknown.
Description edit
The species are mostly perennial herbs, a few are annual or biennial, and some are low subshrubs with woody basal stems. Stems are swollen at the nodes, and contain a clear sap.
The leaves are opposite and simple with entire margins and petioles that wrap around the stem, mostly linear and often strongly glaucous grey-green to blue-green.
The flowers are solitary or in panicles, with leafy bracts beneath and five petals, typically with a frilled or notched margin. In almost all species they are pale to dark pink, but at least one species (D. knappii) has yellow flowers with a purple centre.
Growing conditions edit
Moist, well-drained, not overly rich soils, full sun.
