What are the different Varieties or types of Carnations?

Carnation cultivars are mainly divided into 3 categories/groups depending upon flower size and their use. They are Standard carnation, Spray carnation and Micro carnation. Standard carnations have a single large flower on an individual stem of the plant and mostly used as cut flowers. Spray carnation are small and compact and generally a bunch of flowers on short branches of a single stalk. Micro carnations have shorter stems and higher production than spray cultivars. These carnations are mostly used as ornamental pot plants other than using in flower decorations.
