Abstract

A new and distinct Petunia plant named ‘WNPETSTPER23’, characterized by its upright to outwardly spreading and mounding to eventually trailing and decumbent plant habit; vigorous growth habit and rapid growth rate; freely branching habit; dense and bushy plant form; early and freely flowering habit; single-type flowers that are dark pink in color with bright yellowish green-colored star-shaped centers; and excellent container and garden performance.

Description

Botanical designation: Petunia X hybrida.

Cultivar denomination: ‘WNPETSTPER23’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia X hybrida and hereinafter referred to by the name ‘WNPETSTPER23’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Bonsall, California. The objective of the breeding program is to create new vigorous, freely-branching and uniformly mounding Petunia plants with early and freely flowering habit, attractive flowers and good garden performance.

The new Petunia plant originated from a cross-pollination made by the Inventor on Nov. 12, 2017 in Bonsall, California of a proprietary selection of Petunia X hybrida identified as code number 17PB319-02, not patented, as the female, or seed, parent with a proprietary selection of Petunia X hybrida identified as code number 15P931-02, not patented, as the male, or pollen, parent. The new Petunia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Bonsall, California on Aug. 22, 2018.

Asexual reproduction of the new Petunia plant by vegetative terminal cuttings in a controlled greenhouse environment in Bonsall, California since Aug. 28, 2018 has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘WNPETSTPER23’. These characteristics in combination distinguish ‘WNPETSTPER23’ as a new and distinct Petunia plant:

- 1. Upright to outwardly spreading and mounding to eventually trailing and decumbent plant habit.
- 2. Vigorous growth habit and rapid growth rate.
- 3. Freely branching habit; dense and bushy plant form.
- 4. Early and freely flowering habit.
- 5. Single-type flowers that are dark pink in color with bright yellowish green-colored star-shaped centers.
- 6. Excellent container and garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Petunia are more vigorous than plants of the female parent selection.
- 2. Plants of the new Petunia flower earlier than plants of the female parent selection.
- 3. Flowers of plants of the new Petunia are dark pink in color with bright yellowish green-colored star-shaped centers whereas flowers of plants of the female parent selection are intense purple in color.

Plants of the new Petunia can be compared to plants of the male parent selection. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Petunia are more upright than and not as trailing as plants of the male parent selection.
- 2. Plants of the new Petunia have larger flowers than plants of the male parent selection.
- 3. Flowers of plants of the new Petunia are dark pink in color with bright yellowish green-colored star-shaped centers whereas flowers of plants of the male parent selection are purple in color.

Plants of the new Petunia can be compared to plants of Petunia sensu wijsman ‘DCAS303’, disclosed in U.S. Plant Pat. No. 26,888. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘DCAS303’ in the following characteristics:

- 1. Plants of the new Petunia are more upright and denser than plants of ‘DCAS303’.
- 2. Flowers of plants of the new Petunia are dark pink in color with bright yellowish green-colored star-shaped centers whereas flowers of plants of ‘DCAS303’ are yellow to blush pink in color.
- 3. Plants of the new Petunia have better container and garden performance than plants of ‘DCAS303’.

Plants of the new Petunia can also be compared to plants of Petunia x hybrida ‘Sanguna® Patio Melon Morn’, not patented. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘Sanguna® Patio Melon Morn’ in the following characteristics:

- 1. Plants of the new Petunia are denser than and not as compact as plants of ‘Sanguna® Patio Melon Morn’.
- 2. Flowers of plants of the new Petunia are dark pink in color with bright yellowish green-colored star-shaped centers whereas flowers of plants of ‘Sanguna® Patio Melon Morn’ are coral in color with white-colored centers.
- 3. Plants of the new Petunia have better container and garden performance than plants of ‘Sanguna® Patio Melon Morn’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Petunia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Petunia plant.

The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical flowering plant of ‘WNPETSTPER23’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical flowering plant of ‘WNPETSTPER23 ’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in 740-ml containers in an acrylic-covered greenhouse in Carlton, Michigan and under cultural practices typical of commercial Petunia production. During the production of the plants, day temperatures ranged from 18 C to 32 C and night temperatures ranged from 18 C to 24 C. Plants were pinched two weeks after planting and were five weeks from planting rooted cuttings when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
