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 ‘BBTUN22503’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Bonsall, Calif. 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 double-type flowers and good garden performance.

The new Petunia plant originated from a cross-pollination made by the Inventor on Oct. 16, 2013 in Bonsall, Calif. of Petunia X hybrida ‘USTUNJ2401’, disclosed in U.S. Plant Pat. No. 28,028, as the female, or seed, parent with Petunia X hybrida ‘Sundasiro’, disclosed in U.S. Plant Pat. No. 20,870, 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, Calif. on Jun. 18, 2014.

Asexual reproduction of the new Petunia plant by vegetative terminal cuttings in a controlled greenhouse environment in Bonsall, Calif. since Jun. 27, 2014 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 ‘BBTUN22503’. These characteristics in combination distinguish ‘BBTUN22503’ as a new and distinct Petunia plant:

• • 1. Upright to outwardly spreading and mounding to eventually trailing 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. Double-type flowers that are dark red purple and white in color.
  • 6. Excellent garden performance.

Plants of the new Petunia can be compared to plants of the female parent, ‘USTUNJ2401’. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘USTUNJ2401’ in the following characteristics:

• • 1. Plants of the new Petunia are more vigorous than and not as compact as plants of ‘USTUNJ2401’.
  • 2. Plants of the new Petunia have double-type flowers that are dark red purple and white in color whereas plants of ‘USTUNJ2401’ have single-type flowers that are red purple and white in color.
  • 3. Plants of the new Petunia perform better in the garden than plants of ‘USTUNJ2401’.

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

• • 1. Plants of the new Petunia are more outwardly spreading and not as upright as plants of ‘Sundasiro’.
  • 2. Plants of the new Petunia have double-type flowers that are dark red purple and white in color whereas plants of ‘USTUNJ2401’ have double-type flowers that are white in color.
  • 3. Plants of the new Petunia perform better in the garden than plants of ‘Sundasiro’.

Plants of the new Petunia can be compared to plants of ‘KL 1117’, disclosed in U.S. Plant Pat. No. 25,485. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘KL 1117’ in the following characteristics:

• • 1. Plants of the new Petunia are more outwardly spreading than and not as upright as plants of ‘KL 1117’.
  • 2. Plants of the new Petunia have double-type flowers that are dark red purple and white in color whereas plants of ‘KL 1117’ have single-type flowers that are white in color.
  • 3. Plants of the new Petunia perform better in the garden than plants of ‘KL 1117’.

Plants of the new Petunia can also be compared to plants of ‘Kakegawa S36’, disclosed in U.S. Plant Pat. No. 14,037. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘Kakegawa S36’ in the following characteristics:

• • 1. Plants of the new Petunia are more mounding than plants of ‘Kakegawa S36’.
  • 2. Plants of the new Petunia are more freely branching and denser than plants of ‘Kakegawa S36’.
  • 3. Plants of the new Petunia have double-type flowers that are dark red purple and white in color whereas plants of ‘Kakegawa S36’ have single-type flowers that are magenta in color.
  • 4. Plants of the new Petunia have stronger pathogen tolerance and perform better in the garden than plants of ‘Kakegawa S36’.

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.

At the top of the photographic sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘BBTUN22503’ grown in a container and at the bottom of the photographic sheet is a close-up view of a typical flowering plant of ‘BBTUN22503’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 15.25-cm containers in a polyethylene-covered greenhouse in St. Thomas, Ontario, Canada and under cultural practices typical of commercial Petunia production. During the production of the plants, day temperatures averaged 27° C. and night temperatures averaged 15° C. Plants were pinched three weeks after planting and were ten weeks from planting rooted cuttings when the photographs and description were taken.
