Claims
We claim:
1. A new and distinct variety of Dianthus plant designated
`KLEDG20468` as illustrated and described herein.
Description
Genus and species: Dianthus L.
Variety denomination: `KLEDG20468`.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct variety of
Dianthus, botanically known as Dianthus L., and hereinafter
referred to by the variety name `KLEDG20468`. `KLEDG20468`
originated from a naturally-occurring, whole plant mutation from
the Dianthus parent `KLEDG12163` (U.S. Plant Pat. No. 24,707) in
May 2018 in The Netherlands.
In September 2018, `KLEDG20468` was first vegetatively propagated
by vegetative stem cuttings in Stuttgart, Germany, and subsequently
in Latina, Italy. `KLEDG20468` was found to reproduce true to type
in successive generations of asexual propagation in Stuttgart,
Germany and Latina, Italy via vegetative stem cuttings.
SUMMARY
The following are the most outstanding and distinguishing
characteristics of `KLEDG20468` when grown under normal
horticultural practices in Stuttgart, Germany. 1. Double,
purple-red flowers having a pink border; and 2. Very early
flowering.
DESCRIPTION OF THE PHOTOGRAPH
This new Dianthus plant is illustrated by the accompanying
photograph of plants 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 of a
30-week-old plant taken in May 2019 and is of a whole plant of
`KLEDG20468` showing the foliage, buds, and flowers.
DESCRIPTION
The following detailed descriptions set forth the distinctive
characteristics of `KLEDG20468`. The data which define these
characteristics were collected from asexual reproductions carried
out in Stuttgart, Germany. Data was collected in May 2019 on
7-month old plants grown in a plastic greenhouse. Color references
