The purpose of the present invention is to provide a breeding method for a plant having a blue flower color with a simpler blue color development controlling technique, without requiring complex mechanisms for blue color development that have been previously presented and techniques reproducing such mechanisms. Delphinidin-based anthocyanins, in which the both 3′ and 5′-positions of the anthocyanin B-ring have been glycosylated, and flavone glycosides or flavonol glycosides as copigment are made to coexist in the cells of flower organ such as petals.

A new Dianthus plant designated ‘KLEDG20463’ particularly distinguished by double pink to white flowers with very early flowering, is disclosed.

A new Dianthus plant designated ‘KLEDG20461’ particularly distinguished by double purple flowers with white borders and very early flowering, is disclosed.

A new Dianthus plant designated ‘KLEDG20468’ particularly distinguished by double purple-red flowers with pink borders and very early flowering, is disclosed.

A new Dianthus plant designated ‘KLEDG20469’ particularly distinguished by double white flowers and very early flowering, is disclosed.
