Abstract

A new and distinct cultivar of Petunia plant named ‘Wespecawhite’, characterized by its cascading, roughly spherical growth habit; freely branching plant habit; freely flowering habit; small leaves; and single white-colored flowers with violet blush and purple-colored venation.

Description

Botanical classification/cultivar designation: Petunia×hybrida cultivar Wespecawhite.
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 ‘Wespecawhite’.
The new Petunia is a product of a planned breeding program conducted by the Inventor is 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 98K6384-340 with a proprietary Petunia seedling selection, not patented, as the male, or pollen, parent, identified as code number 98P040. 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 Wespecawhite 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 ‘Wespecawhite’. These characteristics in combination distinguish ‘Wespecawhite’ as a new and distinct Petunia cultivar:
1. Cascading and roughly spherical growth habit.
2. Freely branching plant habit.
3. Freely flowering habit.
4. Small leaves.
5. Single white-colored flowers with violet-colored blush and purple-colored venation.
Plants of the new Petunia are more freely branching, have larger flowers, and have flowers of a different color than plants of the female parent. Plants of the new Petunia have smaller leaves, shorter internodes and smaller flowers than plants of the male parent.
Plants of the cultivar Wespecawhite can be compared to plants of the Petunia cultivar Wespemab, disclosed in U.S. Plant Pat. No. 14,165. However in side-by-side comparisons conducted in Südlohn-Oeding, Germany, plants of the new Petunia and the cultivar Wespemab, differed in the following characteristics:
1. Plants of the new Petunia were shorter than plants of the cultivar Wespemab.
2. Plants of the new Petunia had lighter green-colored leaves than plants of the cultivar Wespemab.
3. Plants of the new Petunia had leaves with shorter petioles than plants of the cultivar Wespemab.
4. Plants of the new Petunia had shorter sepals than plants of the cultivar Wespemab.
5. Plants of the new Petunia had longer peduncles than plants of the cultivar Wespemab.
6. Flower color of the new Petunia was different than flower color of the cultivar Wespemab.
Plants of the cultivar Wespecawhite can also be compared to plants of the Petunia cultivar Weswei, disclosed in U.S. Plant Pat. No. 11,595. However in side-by-side comparisons conducted in Südlohn-Oeding, Germany, plants of the new Petunia and the cultivar Weswei differed in the following characteristics:
1. Plants of the new Petunia had smaller leaves than plants of the cultivar Weswei.
2. Plants of the new Petunia had smaller sepals than plants of the cultivar Weswei.
3. Plants of the new Petunia had shorter peduncles than plants of the cultivar Weswei.
4. Flowers of the new Petunia were smaller than flowers of the cultivar Weswei.
5. Anthers of flowers of the new Petunia and the cultivar Weswei differed in coloration.
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.
The photograph at the top of the sheet comprises a side perspective view of a typical plant of ‘Wespecawhite’.
The photograph at the bottom of the sheet comprises a close-up view of a typical flower of ‘Wespecawhite’.
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.
