Abstract

A new and distinct cultivar of Petunia plant named ‘Sunsurf Aotatsu’, characterized by its trailing and decumbent plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; long flowering period; large dark violet-colored flowers; and good garden performance.

Description

Botanical designation: Petunia×hybrida.
Cultivar denomination: ‘SUNSURF AOTATSU’.
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 ‘Sunsurf Aotatsu’.
The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new freely branching and freely flowering Petunia plants with a trailing plant habit and large and attractive flowers.
The new Petunia plant originated from a cross-pollination made by the Inventor in July, 2009 in Higashiomi, Shiga, Japan of a proprietary selection of Petunia×hybrida identified as code number Px5077-01, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number Px107-5B, 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 Higashiomi, Shiga, Japan in September, 2010.
Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since September, 2010 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 environmental conditions and cultural conditions. 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 ‘Sunsurf Aotatsu’. These characteristics in combination distinguish ‘Sunsurf Aotatsu’ as a new and distinct Petunia plant:
    • 1. Trailing and decumbent plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Early and freely flowering habit.
    • 5. Long flowering period.
    • 6. Large dark violet-colored flowers.
    • 7. Good garden performance.
Plants of the new Petunia can be compared to plants of the female parent selection. 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 freely branching than plants of the female parent selection.
    • 2. Plants of the new Petunia flower later than plants of the female parent selection.
    • 3. Plants of the new Petunia had larger flowers than plants of the female parent selection.
Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ primarily from plants of the male parent selection in time to flower as plants of the new Petunia flower earlier than plants of the male parent selection.
Plants of the new Petunia can also be compared to plants of the Petunia ‘Sunsurfgigabu’, disclosed in U.S. Plant Pat. No. 17,645. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Petunia and ‘Sunsurfgigabu’ differed primarily in the following characteristics:
    • 1. Plants of the new Petunia were taller and broader than plants of ‘Sunsurfgigabu’.
    • 2. Plants of the new Petunia had shorter internodes than plants of ‘Sunsurfgigabu’.
    • 3. Plants of the new Petunia had smaller leaves than plants of ‘Sunsurfgigabu’.
    • 4. Plants of the new Petunia were more freely flowering than plants of ‘Sunsurfgigabu’.
    • 5. Plants of the new Petunia had smaller flowers than plants of ‘Sunsurfgigabu’.
    • 6. Plants of the new Petunia had longer peduncles than plants of ‘Sunsurfgigabu’.
    • 7. Plants of the new Petunia and ‘Sunsurfgigabu’ differed in flower color as plants of ‘Sunsurfgigabu’ had purple violet-colored flowers.
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 top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunsurf Aotatsu’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunsurf Aotatsu’.
 DETAILED BOTANICAL DESCRIPTION
