Abstract

A new Petunia plant particularly distinguished by medium brilliant red-purple flowers and a semi-trailing habit, is disclosed.

Description

Genus and species: Petunia hybrida.

Variety denomination: ‘KLEPH17318’.

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 ‘KLEPH17318’. ‘KLEPH17318’ originated from a cross-pollination conducted in July 2012 in Latina, Italy between the female Petunia variety, WHISPERS ‘Star Rose’, also known as ‘PEHY0004’ (U.S. Plant Pat. No. 23,432) and the male Petunia variety POTUNIA ‘Pinkalicious’ (patent status unknown).

The seeds from the cross were sown and plants were grown in a greenhouse for evaluation, where an individual plant designated ‘KLEPH17318’ was selected from the group of plants in April 2013 in Latina, Italy. In May 2013, ‘KLEPH17318’ was first vegetatively propagated by terminal tip cuttings in Latina, Italy. ‘KLEPH17318’ 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 Stuttgart, Germany and Latina, Italy.

- 1. Medium, brilliant red-purple flowers; and
- 2. A semi-trailing habit.

DESCRIPTION OF THE PHOTOGRAPHS

This new Petunia plant is illustrated by the accompanying photographs of a plant grown outdoors in Miami, Fla. The photographs were taken in March 2017 of an 18-week-old plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

FIG. 1 shows the foliage and flowers.

FIG. 2 shows an up close view of a flower.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘KLEPH17318’. The data which define these characteristics were collected from asexual reproductions carried out in Latina, Italy. Data was collected on plants 17-weeks old (about 10 weeks of cultivation in a plactic greenhouse and about 7 weeks outside) Latina, Italy in September 2018. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^thedition (2007).
