Petunia plant named ‘Wespequeen’

Abstract

A distinct cultivar of Petunia plant named ‘Wespequeen’, characterized by its cascading growth habit; freely flowering habit; single bicolored flowers that are purple in color with white-colored margins; light bluish violet-colored anthers; and large sepals.

Description

Botanical classification/cultivar designation: Petunia×hybrida cultivar Wespequeen.

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 ‘Wespequeen’.

The new Petunia is a product of a planned breeding program conducted by the Inventor in Südlohn-Oeding, Germany. The new Petunia originated from a cross-pollination made by the Inventor of a proprietary Petunia seedling selection, not patented, as the female, or seed parent, identified as code number 99P078 with a proprietary Petunia seedling selection not patented, as the male, or pollen, parent, identified as code number 99P048. The new Petunia was selected by the Inventor in 2000 in a controlled environment in Südlohn-Oeding, Germany.

Asexual reproduction of the new cultivar by terminal cuttings in Südlohn-Oeding, Germany since 2001, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar ‘Wespequeen’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, 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 ‘Wespequeen’. These characteristics in combination distinguish ‘Wespequeen’ as a new and distinct Petunia cultivar:

1. Cascading growth habit.

2. Freely flowering habit.

3. Single bicolored flowers that are purple in color with white-colored margins.

4. Light bluish violet-colored anthers.

5. Large sepals.

Plants of the new Petunia produce flowers that are larger and darker in color than plants of the female parent, a proprietary selection. Plants of the new Petunia have a more cascading plant habit and have larger and darker colored flowers than plants of the male parent, a proprietary selection.

Plants of the cultivar Wespequeen can be compared to plants of the Petunia cultivar Brevt, described in U.S. Plant Pat. No. 12,679. However in side-by-side comparisons conducted in Südlohn-Oeding, Germany, plants of the new Petunia and the cultivar Brevt, differed in the following characteristics:

1. Plants of the new Petunia had shorter internodes than plants of the cultivar Brevt.

2. Plants of the new Petunia had larger flowers with larger sepals than plants of the cultivar Brevt.

3. Flower color of plants of the new Petunia was different than flower color of plants of the cultivar Brevt.

4. Plants of the new Petunia had longer peduncles than plants of the cultivar Brevt.

5. Flowers of the new Petunia had anthers of a different color than flowers of the cultivar Brevt.

Plants of the cultivar ‘Wespequeen’ can also be compared to plants of the Petunia cultivar Bresh, disclosed in U.S. Plant patent application Ser. No. 09/592,379, now abandoned. However in side-by-side comparisons conducted in Südlohn-Oeding, Germany, plants of the new Petunia and the cultivar Bresh differed in the following characteristics:

1. Plants of the new Petunia had shorter internodes than plants of the cultivar Bresh.

2. Plants of the new Petunia had larger flowers with larger sepals than plants of the cultivar Bresh.

3. Flower color of plants of the new Petunia was more intense than flower color of plants of the cultivar Bresh.

4. Flowers of the new Petunia had anthers of a different color than flowers of the cultivar Bresh.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, 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.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the aformentioned photographs and the following botanical description were grown in 12-cm containers during the spring and summer for about 20 weeks in a glass-covered greenhouse and under conditions that closely approximate commercial production conditions in Südlohn-Oeding, Germany. During the production of the plants, day temperatures were about 20 to 25° C., night temperatures were about 16 to 18° C. and light levels ranged from 3,000 to 50,000 lux.
