| Abstract: |
A new and distinct cultivar of Pieris plant named `Passion`, characterized by its upright and outwardly spreading plant habit; freely branching habit; large inflorescences with numerous red purple-colored flowers; developing inflorescences upright; and good garden performance. |
| Claim: |
It is claimed:
1. A new and distinct cultivar of Pieris plant named `Passion` as illustrated and described. |
| Description: |
Botanical designation:Pieris japonica.
Cultivar denomination: `Passion`.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Pieris, botanically known as Pieris japonica, and hereinafter referred to by the name `Passion`.
The new Pieris is a product of a planned breeding program conducted by the Inventor in Boskoop, The Netherlands. The objective of the breeding program is to create new Pieris varieties having upright inflorescences and attractive flower color.
The new Pieris originated from a cross-pollination made by the Inventor in March, 1988, in Boskoop, The Netherlands, of an unnamed seedling selection of Pieris japonica, not patented, as the female, or seed, parent with the Pieris japonicacultivar Valley Valentine, not patented, as the male, or pollen, parent. The new Pieris was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Boskoop, TheNetherlands in March 1999.
Asexual reproduction of the new Pieris by cuttings taken in a controlled environment in Boskoop, The Netherlands since 2000 has shown that the unique features of this new Pieris are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The new Pieris has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and/or light intensity without, however, any variance in genotype. Thefollowing traits have been repeatedly observed and are determined to be the unique characteristics of `Passion`. These characteristics in combination distinguish `Passion` as a new and distinct cultivar of Pieris: 1. Upright and outwardly spreadingplant habit. 2. Freely branching habit. 3. Large inflorescences with numerous red purple-colored flowers. 4. Developing inflorescences upright. 5. Good garden performance.
Plants of the new Pieris differ from plants of the female parent selection primarily in flower color as plants of the female parent selection have white-colored flowers.
Plants of the new Pieris differ from plants of the male parent, the cultivar Valley Valentine, in the following characteristics: 1. Plants of the new Pieris develop roots more easily than plants of the cultivar Valley Valentine. 2. Plants ofthe new Pieris are more freely branching than plants of the cultivar Valley Valentine. 3. Inflorescences of plants of the new Pieris are more upright than inflorescences of plants of the cultivar Valley Valentine.
Plants of the new Pieris can be compared to the plants of the Pieris cultivar Rosalinda, not patented. In side-by-side comparisons conducted in Boskoop, The Netherlands, plants of the new Pieris differed from plants of the cultivar Rosalinda inthe following characteristics: 1. Developing leaves of plants of the new Pieris were light green in color whereas developing leaves of plants of the cultivar Rosalinda were brownish red in color. 2. Flowers of plants of the new Pieris were red purplein color whereas flowers of plants of the cultivar Rosalinda were light pink in color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the Pieris. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this describe the colors of the new Pieris.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of `Passion` grown in a container.
The photograph at the top of the second sheet is a close-up view of a typical leaf of `Passion`.
The photograph at the bottom of the second sheet is a close-up view of typical flowering stems of `Passion`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Boskoop, The Netherlands in 17-cm containers, in a glass-covered greenhouse during the winter and under commercial production conditions. Duringthe production of the plants, day temperatures ranged from 7.degree. C. to 16.degree. C. and night temperatures ranged from 2.degree. C. to 10.degree. C. Plants used for the photographs and description were about four years old. In the followingdescription, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
