Dianthus plant named ‘KLEDP25525’

Abstract

A new Dianthus plant designated ‘KLEDP25525’ particularly distinguished by bicolored flowers with dark red centers and white along the edge of the petals; and tall, upright plants with shorter flower stems on top, is disclosed.

Description

[0001] Genus and species: Dianthus x caryophyllus L. hort.

[0002] Variety denomination: ‘KLEDP25525’.BACKGROUND OF THE NEW PLANT

[0003] The present invention comprises a new and distinct variety of Dianthus, botanically known as Dianthus x caryophyllus L. hort. and hereinafter referred to by the variety name ‘KLEDP25525’. In 2018 a whole plant mutation was identified within a group of Dianthus ‘KLEDP07089’ at a plant production facility in the Netherlands and the plant was subsequently shipped to Stuttgart, Germany. The mutation was evaluated and selected for by the inventor in Stuttgart, Germany and named ‘KLEDP25525’. In May 2018, ‘KLEDP25525’ was first vegetatively propagated by vegetative stem cuttings in Stuttgart, Germany. ‘KLEDP25525’ was found to reproduce true to type in successive generations of asexual propagation in Stuttgart, Germany via vegetative cuttings.SUMMARY

[0004] The following are the most outstanding and distinguishing characteristics of ‘KLEDP25525’ when grown under normal horticultural practices in Stuttgart, Germany.

[0005] 1. Bicolored flowers with dark red centers and white along the edge of the petals; and

[0006] 2. Tall, upright plants with shorter flower stems on top.DESCRIPTION OF THE PHOTOGRAPH

[0007] This new Dianthus plant is illustrated by the accompanying photograph of an 11-week-old plant taken in March 2023 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 photograph of ‘KLEDP25525’ and shows the foliage, buds, and flowers.DESCRIPTION

[0008] The following detailed descriptions set forth the distinctive characteristics of ‘KLEDP25525’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. Data was collected in May 2024 from plants potted in week 41 of 2021 grown in a greenhouse. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5th edition (2007).
