The Dianthus Flower has a very interesting history that landscape gardeners would be interested in. There are many types and varieties of this flower. Sweet William, Carnations and Pinks belong to the genus Dianthus. The ancient Greeks were very keen on flowers and call the carnation the “divine flower”. The Greeks used flowers for landscaping gardens of the noble classes. In Britain, the Elizabethans grew a wide variety of pinks. In Irish landscapers gardens today you will find varieties of the Dianthus flower in rockeries, beds and windows boxes. The flowering period depends of which variety you are using.
