What are Carnations?

Dianthus (pinks of carnations) belongs in the Caryophyllaceae family; there are around 88 genera and around 300 species in this family have been identified; there are also hundreds of hybrid varieties.

Carnations are all (botanically), the species "Dianthus caryophyllus" - there are of course several hundred species of Dianthus (Sweet William is Dianthus barbatus.) The perpetual flowering carnation originated from Dianthus caryophyllus being bred with other species of Dianthus - at least with Dianthus sinensis. This type is reported to have been bred in Lyons, France around 1830.


This course will be relevant to any of the many species in the genus Dianthus (carnations).
