About
Dianthus ( dy-AN-thəs) is a genus of about 340 species of flowering plants in the family Caryophyllaceae, native mainly to Europe and Asia, with a few species in northern and southern Africa, and one species (D. repens) in arctic North America. A least two species are introduced in North America: Dianthus armeria and Dianthus deltoides. Common names include carnation (D. caryophyllus), pink (D. plumarius and related species), and sweet william (D. barbatus).
How to grow it
Since 1717, dianthus species have been extensively bred and hybridised to produce many thousands of cultivars for garden use and floristry, in all shades of white, pink, yellow, and red, with a huge variety of flower shapes and markings. They are often divided into the following main groups:
Border carnations – fully hardy, growing to 60 cm (24 in), large blooms
Where it grows
Dianthus species are used as food plants by the larvae of some Lepidoptera species including cabbage moth, double-striped pug, large yellow underwing, and the lychnis. Also three species of Coleophora case-bearers feed exclusively on Dianthus; C. dianthi, C. dianthivora, and C. musculella (which feeds exclusively on D. superbus).
