Description

[0001] Genus and species: Dahlia sp.

[0002] Variety denomination: ‘KLEDH24724’.BACKGROUND

[0003] The present invention comprises a new and distinct variety of Dahlia, botanically known as Dahlia sp., and hereinafter referred to by the variety name ‘KLEDH24724’. ‘KLEDH24724’ originated from an open pollination in a field with the female ‘KLEDH18127’ (U.S. Plant Pat. No. 32,750) and an unknown male Dahlia plant in the summer of 2020 in Latina, Italy. In March 2021 a seedling was selected and named ‘KLEDH24724’. ‘KLEDH24724’ was first vegetatively propagated by vegetative cuttings in May 2021 in Stuttgart, Germany. ‘KLEDH24724’ was found to reproduce true to type in successive generations of asexual propagation.SUMMARY

[0004] The following are the most outstanding and distinguishing characteristics of ‘KLEDH24724’ when grown under normal horticultural practices in Latina, Italy.

[0005] 1. Light pink flowers with darker shades of pink at distal quarter of ray florets; and

[0006] 2. Semi-upright plant habit.DESCRIPTION OF THE PHOTOGRAPH

[0007] This new Dahlia plant is illustrated by the accompanying photograph of the plant approximately fourteen weeks old and grown in a greenhouse in Stuttgart, Germany. The photograph shows the whole plant, unless otherwise noted, including the inflorescences and foliage and buds and was taken in May 2024 in Stuttgart, Germany. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.DESCRIPTION OF ‘KLEDH24724’

[0008] The following detailed descriptions set forth the distinctive characteristics of ‘KLEDH24724’. The data which define these characteristics were collected from asexual reproductions carried out in Latina, Italy. Data was collected on 16-week-old plants, with one pinch and 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).
