Description

Botanical designation: Petunia X hybrida.

Cultivar denomination: ‘USTUN2401M’.

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 ‘USTUN2401M’.

The new Petunia plant is a naturally-occurring branch mutation of Petunia X hybrida ‘USTUNJ2401’, disclosed in U.S. Plant Pat. No. 28,028. The new Petunia plant was discovered and selected by the Inventor on a single flowering plant within a population of plants of ‘USTUNJ2401’ in a controlled greenhouse environment in Loudon, N.H. in early January, 2015.

Asexual reproduction of the new Petunia plant by vegetative terminal cuttings in a controlled greenhouse environment in Loudon, N.H. since January, 2015 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 ‘USTUN2401M’. These characteristics in combination distinguish ‘USTUN2401M’ as a new and distinct Petunia plant:

    • 1. Compact, outwardly spreading and mounding to eventually trailing plant habit.
    • 2. Freely branching habit.
    • 3. Vigorous growth habit.
    • 4. Early and freely flowering habit.
    • 5. Hot pink-colored flowers.
    • 6. Good garden performance.

Plants of the new Petunia can be compared to plants of the mutation parent, ‘USTUNJ2401’. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘USTUNJ2401’ in flower color as plants of ‘USTUNJ2401’ have white-colored flowers with a distinct and stable red purple star-shaped color pattern.

Plants of the new Petunia can be compared to plants of ‘USTUN34803’, disclosed in U.S. Plant Pat. No. 22,884. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘USTUN34803’ in the following characteristics:

    • 1. Plants of the new Petunia are more mounding than plants of ‘USTUN34803’.
    • 2. Plants of the new Petunia and ‘USTUN34803’ differ in flower color as plants of ‘USTUN34803’ have red purple-colored flowers.

Plants of the new Petunia can also be compared to plants of ‘USTUN19603’, disclosed in U.S. Plant Pat. No. 21,675. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘USTUN19603’ in the following characteristics:

    • 1. Plants of the new Petunia are more mounding than plants of ‘USTUN19603’.
    • 2. Plants of the new Petunia flower earlier than plants of ‘USTUN19603’.
    • 3. Flowers of plants of the new Petunia are darker pink than flowers of plants of ‘USTUN19603’.

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 at the bottom of the sheet is a side perspective view of a typical flowering plant of ‘USTUN2401M’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘USTUN2401M’.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the early spring in 11.5-cm containers in an acrylic-covered greenhouse in Carleton, Mich. and under cultural practices typical of commercial Petunia production.
