plant named ‘KLEPH19120’

Abstract

A new Petunia plant particularly distinguished by having a violet flower color with a well-defined white border, is disclosed.

Description

Genus and species: Petunia hybrida.

Variety denomination: ‘KLEPH19120’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Petunia, botanically known as Petunia hybrida and hereinafter referred to by the variety name ‘KLEPH19120’. ‘KLEPH19120’ is a selection from a cross-pollination of the proprietary female Petunia line ‘PH-2014-0310’ (unpatented) and the proprietary male Petunia line ‘PH-2014-0316’ (unpatented).

In July of 2014, the proprietary female Petunia line ‘PH-2014-0310’ and the proprietary male Petunia line ‘PH-2014-0316’ were cross pollinated in Latina, Italy and seeds were obtained. The seeds were sown and plants were grown for evaluation. A plant line was selected in April 2015 in Latina, Italy and named ‘KLEPH19120’. In May 2015, ‘KLEPH19120’ was first vegetatively propagated by terminal tip cuttings and tissue culture in Latina, Italy. ‘KLEPH19120’ was found to reproduce true to type in successive generations of asexual propagation via tissue culture and terminal tip cuttings.

SUMMARY

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

• • 1. Violet flower color with well-defined white border.

DESCRIPTION OF THE PHOTOGRAPH

This new Petunia plant is illustrated by the accompanying photograph, which shows a close-up of the flower of the plant. The plant is about 11 weeks old grown in Stuttgart, Germany in June 2019. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘KLEPH19120’. The data which define these characteristics were collected from asexual reproductions carried out in Latina, Italy. Data was collected on fourteen-week-old plants grown indoors in Latina, Italy under greenhouse conditions in March 2020. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^th edition (2007).
