Dianthus plant named ‘KLEDA25852’

Abstract

A new Dianthus plant named ‘KLEDA25852’ particularly distinguished by many flower stems per plant, a compact and dense plant base, and a white flower color with burgundy macule, is disclosed.

Description

[0001] Genus and species: Dianthus x allwoodii hort.

[0002] Variety denomination: ‘KLEDA25852’.BACKGROUND OF THE NEW PLANT

[0003] The present invention comprises a new and distinct variety of Dianthus, botanically known as Dianthus x allwoodii hort. and hereinafter referred to by the variety name ‘KLEDA25852’. ‘KLEDA25852’ originated from an open cross pollination between the proprietary female parent ‘PIE.134’ (unpatented) and an unknown male parent between May 2018 and August 2018.

[0004] In June 2019, ‘KLEDA25852’ was selected and in September 2019, ‘KLEDA25852’ was first vegetatively propagated by vegetative cuttings in Ashcombe, Dawlish, United Kingdom. ‘KLEDA25852’ was found to reproduce true to type in successive generations of asexual propagation in Stuttgart, Germany via vegetative cuttings.SUMMARY

[0005] The following are the most outstanding and distinguishing characteristics of ‘KLEDA25852’ when grown under normal horticultural practices in Stuttgart, Germany.

[0006] 1. many flower stems per plant,

[0007] 2. a compact and dense plant base, and

[0008] 3. a white flower color with burgundy maculeDESCRIPTION OF THE PHOTOGRAPH

[0009] This new Dianthus plant is illustrated by the accompanying photograph of a 9-month-old plant taken in June 2023 indoor in Dawlish Devon, United Kingdom. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is a whole plant photo of ‘KLEDA25852’ and shows the foliage, buds, and flowers.DESCRIPTION
