Title: Petunia Plant Named &#39;G13460&#39;

Description:
Botanical designation:  Petunia×hybrida.    
     Cultivar denomination: ‘G13460’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Petunia  plant, botanically known as  Petunia×hybrida  and hereinafter referred to by the name ‘G13460’. 
     The new  Petunia  plant is a product of a planned breeding program conducted by the Inventor in Bellefonte, Pa. The objective of the breeding program is to create new freely-branching, cascading to trailing  Petunia  plants with early and freely flowering habit, unique attractive flowers and good garden performance. 
     The new  Petunia  plant originated from a cross-pollination made by the Inventor in January, 2013 in Bellefonte, Pa. of a proprietary seedling selection of  Petunia×hybrida  identified as code number 8204-1, not patented, as the female, or seed, parent with a proprietary selection of  Petunia×hybrida  identified as code number 20284-2, 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 Bellefonte, Pa. on Oct. 18, 2013. 
     Asexual reproduction of the new  Petunia  plant by vegetative terminal cuttings in a controlled greenhouse environment in Bellefonte, Pa. since Nov. 13, 2013 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 ‘G13460’. These characteristics in combination distinguish ‘G13460’ as a new and distinct  Petunia  plant:
         1. Outwardly spreading to trailing and mounding plant habit.   2. Vigorous growth habit.   3. Freely branching habit.   4. Early and freely flowering habit; long flowering period.   5. Strong red-colored flowers.   6. Good 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  have smaller leaves than plants of the female parent selection.   2. Plants of the new  Petunia  have smaller flowers than plants of the female parent selection.   3 Throats of flowers of plants of the new  Petunia  are lighter in color than throats of flowers of plants of the female parent selection.       

     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 trailing than and not as prostrate as plants of the male parent selection.   2. Plants of the new  Petunia  are more freely branching than plants of the male parent selection.   3. Plants of the new  Petunia  have larger flowers than plants of the male parent selection.       

     Plants of the new  Petunia  can be compared to plants of ‘USTUNI223’, disclosed in U.S. Plant Pat. No. 14,871. In side-by-side comparisons, plants of the new  Petunia  differ primarily from plants of ‘USTUNI223’ in the following characteristics:
         1. Leaves of plants of the new  Petunia  are narrower than leaves of plants of ‘USTUNI223’.   2. Plants of the new  Petunia  and ‘USTUNI223’ differ in flower color as plants of ‘USTUNI223’ have lighter red-colored flowers with darker-colored throat venation.   3. Plants of the new  Petunia  have longer and more narrow sepals than plants of ‘USTUNI223’.       

     Plants of the new  Petunia  can be compared to plants of ‘Balsuncared’, not patented. In side-by-side comparisons, plants of the new  Petunia  differ primarily from plants of ‘Balsuncared’ in the following characteristics:
         1. Plants of the new  Petunia  are more trailing than and not as upright as plants of ‘Balsuncared’.   2. Plants of the new  Petunia  and ‘Balsuncared’ differ in flower color as plants of ‘Balsuncared’ have darker red-colored flower throats than plants of the new  Petunia.
