Abstract

A new and distinct cultivar of Petunia plant named ‘Sunsurf Piusa’, characterized by its compact and mounding plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; long flowering period; small bright red purple-colored flowers; and good garden performance.

Description

Botanical designation: Petunia×hybrida.
Cultivar denomination: ‘SUNSURF PIUSA’.
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 Piusa’.
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 compact, freely branching and freely flowering Petunia plants with mounding habit and attractive flower coloration.
The new Petunia plant originated from a cross-pollination made by the Inventor in January, 2005 in Higashiomi, Shiga, Japan of a proprietary selection of Petunia×hybrida identified as code name Px139-02, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code name BR-01, 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 November, 2007.
Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since November, 2007 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 Piusa’. These characteristics in combination distinguish ‘Sunsurf Piusa’ as a new and distinct Petunia plant:
    • 1. Compact and mounding plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Early and freely flowering habit.
    • 5. Long flowering period.
    • 6. Small bright red purple-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 flower color as plants of the female parent selection have dark red purple-colored flowers.
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 the following characteristics:
    • 1. Plants of the new Petunia are more compact than plants of the male parent selection.
    • 2. Plants of the new Petunia have larger flowers than plants of the male parent selection.
Plants of the new Petunia can also be compared to plants of the Petunia ‘Sunsurfcoparu’, disclosed in U.S. Plant Pat. No. 18,141. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Petunia and ‘Sunsurfcoparu’ differed primarily in the following characteristics:
    • 1. Plants of the new Petunia were taller than plants of ‘Sunsurfcoparu’.
    • 2. Plants of the new Petunia had shorter internodes than plants of ‘Sunsurfcoparu’.
    • 3. Plants of the new Petunia had slightly larger leaves with longer petioles than plants of ‘Sunsurfcoparu’.
    • 4. Plants of the new Petunia had larger flowers than plants of ‘Sunsurfcoparu’.
    • 5. Flowers of plants of the new Petunia were longer lasting than flowers of plants of ‘Sunsurfcoparu’.
    • 6. Petal apices of plants of the new Petunia were mucronate in shape whereas petal apices of plants of ‘Sunsurfcoparu’ were truncate in shape.
    • 7. Plants of the new Petunia and ‘Sunsurfcoparu’ differed in flower color as plants of ‘Sunsurfcoparu’ had pink-colored flowers.
    • 8. Plants of the new Petunia had shorter peduncles than plants of ‘Sunsurfcoparu’.
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 Piusa’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunsurf Piusa’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Petunia production.
