Genus and species: Petunia hybrida.

Variety denomination: ‘KLEPH17300’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit of European Community Plant Variety Rights application filed on Mar. 13, 2018, File No. 2018/0754, the entire contents of which are incorporated herein by reference for all purposes.

‘KLEPH17008’ has not been made publicly available for more than one year prior to the effective filing date of the present application.

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 ‘KLEPH17300’. ‘KLEPH17300’ originated from a cross-pollination conducted in July 2012 in Latina, Italy between the female Petunia variety, ‘Duesurmar’, also commercially known as SURPRISE ‘Marine’ (U.S. Plant Pat. No. 21,673) and the male Petunia variety VIVA ‘Blue Ocean’ (patent status unknown).

The seeds from the cross were sown and plants were grown in a greenhouse for evaluation, where an individual plant designated ‘KLEPH17300’ was selected from the group of plants in April 2013 in Latina, Italy. In May 2013, ‘KLEPH17300’ was first vegetatively propagated by terminal tip cuttings in Latina, Italy. ‘KLEPH17300’ 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. Large, purple flowers; and
  • 2. A trailing habit.

DESCRIPTION OF THE PHOTOGRAPH

This new Petunia plant is illustrated by the accompanying photograph of a plant grown in a plastic greenhouse in Stuttgart, Germany. The photograph was taken in May 2016 and shows the foliage and flowers of a 12-week-old plant grown in a pot. 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 ‘KLEPH17300’. The data which define these characteristics were collected from asexual reproductions carried out in Latina, Italy. Data was collected on plants grown 16-weeks from cultivation from potting in a plastic greenhouse in Latina, Italy in April 2018. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^th edition (2007).
