Abstract

A distinct cultivar of Petunia plant named `Wespur`, characterized by its compact plant habit; relatively small leaves; numerous purple flowers; cascading and freely branching growth habit; early flowering; and good weather tolerance, particlarly tolerant to rain, wind and low temperatures.

Description

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 cultivar name `Wespur`.
The new Petunia is a product of a planned breeding program conducted by the Inventor in Sudlohn-Oeding, Germany. The new Petunia originated from a cross made by the Inventor in 1996 in Sudlohn-Oeding, Germany, of a seedling selection of Petunia×hybrida identified as Sylvana 95/304 as the female, or seed, parent with the nonpatented Petunia×hybrida cultivar Sylvana Purple as the male, or pollen parent.
Asexual reproduction of the new cultivar by terminal cuttings taken at Sudlohn-Oeding, Germany, 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 Wespur have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Wespur`. These characteristics in combination distinguish `Wespur` as a new and distinct cultivar:
1. Compact plant habit.
2. Relatively small leaves.
3. Numerous purple flowers.
4. Cascading and freely branching growth habit.
5. Relatively early flowering.
6. Good weather tolerance, particularly tolerant to rain, wind and low temperatures.
Plants of the cultivar Wespur are similar in flower color to plants of the nonpatented `Surfinia Purple`. However in side-by-side comparisons conducted in Sudlohn-Oeding, Germany, plants of the cultivar Wespur differ from plants of the cultivar Surfinia Purple in the following characteristics:
1. Plants of the new Petunia are more compact than of plants of the cultivar Surfinia Purple.
2. Leaves of plants of the new Petunia are smaller than leaves of plants of the cultivar Surfinia Purple.
3. Plants of the new Petunia have more but smaller flowers than plants of the cultivar Surfinia Purple.
4. Plants of the new Petunia flower earlier than plants of the cultivar Surfinia Purple.
5. Plants of the new Petunia exhibit better weather tolerance, particularly to rain, than plants of the cultivar Surfinia Purple.
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.
FIG. 1 comprises a side perspective view of typical flowers of the new Petunia.
FIG. 2 comprises a close-up view of a typical flower of the new Petunia. Flower and foliage colors in the photographs may appear different than the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
