plant named ‘KLEDG19303’

Abstract

A new Dianthus plant named ‘KLEDG19303’ particularly distinguished by single flowers with a magenta flower color with a purple center, a maculated flower pattern and green-grey leaf color, is disclosed.

Description

Genus and species: Dianthus cultivars.

Variety denomination: ‘KLEDG19303’.

BACKGROUND OF VARIETY ‘KLEDG19303’

The present invention comprises a new and distinct variety of Dianthus, botanically known as Dianthus cultivars and hereinafter referred to by the variety name ‘KLEDG19303’. ‘KLEDG19303’ is a selection that resulted from an open pollination of the proprietary female Dianthus line ‘DSU-2011-0033’ (unpatented) and the proprietary male Dianthus line ‘DSS-2011-0047’.

In May of 2014, the proprietary female Dianthus line ‘DSU-2011-0033’ and the proprietary male Dianthus line ‘DSS-2011-0047’ were cross pollinated in Stuttgart, Germany and seeds were obtained. The seeds were sown and plants were grown for evaluation. A plant line was selected in June of 2015 in Stuttgart, Germany, and named ‘KLEDG19303’. In September of 2015, ‘KLEDG19303’ was first vegetatively propagated by vegetative cuttings. ‘KLEDG19303’ was found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings in Stuttgart, Germany and Latina, Italy.

SUMMARY OF VARIETY ‘KLEDG19303’

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Latina, Italy.

• • 1. Single flowers with a magenta flower color with a purple center;
  • 2. A maculated flower pattern; and
  • 3. Green-grey leaf color.
