CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit of U.S. Provisional Application No. 62/973,972, filed on Nov. 4, 2019, the entire contents of which are incorporated herein by reference for all purposes.

Genus and species: Dianthus L.

Variety denominations: ‘KLEDG20461’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Dianthus, botanically known as Dianthus L., and hereinafter referred to by the variety name ‘KLEDG20461’. ‘KLEDG20461’ originated from a naturally-occurring, whole plant mutation from the Dianthus parent ‘KLEDG12163’ (U.S. Plant Pat. No. 24,707) in June 2018 in The Netherlands.

In September 2018, ‘KLEDG20461’ was first vegetatively propagated by vegetative stem cuttings in Stuttgart Germany, and subsequently in Latina, Italy. ‘KLEDG20461’ was found to reproduce true to type in successive generations of asexual propagation in Stuttgart, Germany and Latina, Italy via vegetative stem cuttings.

SUMMARY

The following are the most outstanding and distinguishing characteristics of ‘KLEDG20461’ when grown under normal horticultural practices in Stuttgart, Germany.

• • 1. Double, purple flowers with white borders; and
  • 2. Very early flowering.

DESCRIPTION OF THE PHOTOGRAPH

This new Dianthus plant is illustrated by the accompanying photograph of a 30-week-old plant taken in May 2019 and grown in a greenhouse in Stuttgart, Germany. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

The photograph is a whole plant photo of ‘KLEDG20461’ and shows the foliage, buds, and flowers.

DESCRIPTION

The following detailed descriptions set forth the distinctive characteristics of ‘KLEDG20461’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. Data was collected in May 2019 on 7-month old plants grown in a plastic greenhouse. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^th edition (2007).
