Dianthus plant named ‘KLEDG22394’

Abstract

A new Dianthus plant designated ‘KLEDG22394’ particularly distinguished by single, white flowers with purple patterns with winter hardiness, is disclosed.

Description

Genus and species: Dianthus caryophyllus L.

Variety denomination: ‘KLEDG22394’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Dianthus, botanically known as Dianthus caryophyllus L., and hereinafter referred to by the variety name ‘KLEDG22394’. ‘KLEDG22394’ originated from a cross pollination from the proprietary female parent ‘DSS-2014-1025’ (unpatented) and proprietary male parent ‘DSS-2014-1002’ (unpatented) in 2015 between May and August in Stuttgart, Germany.

A plant line was selected in June 2016 in Stuttgart, Germany, and named ‘KLEDG22394’. In July 2016, ‘KLEDG22394’ was first vegetatively propagated by vegetative stem cuttings in Stuttgart, Germany. ‘KLEDG22394’ was found to reproduce true to type in successive generations of asexual propagation in Stuttgart, Germany via vegetative cuttings.

SUMMARY

The following are the most outstanding and distinguishing characteristics of ‘KLEDG22394’ when grown under normal horticultural practices in Stuttgart, Germany.

• • 1. Single, white flowers with purple patterns; and
  • 2. Winter-hardiness.

DESCRIPTION OF THE PHOTOGRAPH

This new Dianthus plant is illustrated by the accompanying photograph of a 14-week-old plant taken in March 2019 and grown indoors 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 ‘KLEDG22394’ and shows the foliage, buds, and flowers.

DESCRIPTION

The following detailed descriptions set forth the distinctive characteristics of ‘KLEDG22394’. The data which define these characteristics were collected from asexual reproductions carried out in Latina, Italy. Data was collected in March 2023 from 21-week-old plants that were potted in October 2022 and 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).
