Description

Botanical designation: Petunia x hybrida.

Cultivar denomination: ‘SUNPETU 211’.

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 ‘Sunpetu 211’.

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 upright, mounding and freely-flowering Petunia plants with attractive flower colors and patterns.

The new Petunia plant originated from a cross-pollination made by the Inventor in July, 2014 in Higashiomi, Shiga, Japan of a proprietary selection of Petunia x hybrida identified as code designation SA8294, not patented, as the female, or seed, parent with a proprietary selection of Petunia x hybrida identified as code designation PSRS, 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 July, 2015.

Asexual reproduction of the new Petunia plant by terminal vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since January, 2016 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 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 ‘Sunpetu 211’. These characteristics in combination distinguish ‘Sunpetu 211’ as a new and distinct Petunia plant:

• • 1. Upright and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. Large flowers that are bright purple with a white-colored star pattern.
  • 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 violet-colored flowers with a white-colored star pattern. In addition, flowers of plants of the new Petunia are larger than flowers of 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 flower color as plants of the male parent selection have rose pink-colored flowers with a white-colored star pattern.

Plants of the new Petunia can also be compared to plants of the Petunia hybrid ‘PBLRS38-0’, disclosed in U.S. Plant Pat. No. 25,265. In side-by-side comparisons, plants of the new Petunia and ‘PBLRS38-0’ differ primarily in the following characteristics:

• • 1. Plants of the new Petunia are more upright than and not as outwardly spreading as plants of ‘PBLRS38-0’.
  • 2. Plants of the new Petunia are taller than and not as broad as plants of ‘PBLRS38-0’.
  • 3. Plants of the new Petunia have larger leaves than plants of ‘PBLRS38-0’.
  • 4. Plants of the new Petunia are more freely flowering than plants of ‘PBLRS38-0’.
  • 5. Plants of the new Petunia have larger flowers than plants of ‘PBLRS38-0’.
